User Roles Required to Work with Carrier Ethernet Services

This topic identifies the roles that are required to work with to Carrier Ethernet services in Prime Network Vision. Prime Network determines whether you are authorized to perform a task as follows:

For GUI-based tasks (tasks that do not affect elements), authorization is based on the default permission that is assigned to your user account.

For element-based tasks (tasks that do affect elements), authorization is based on the default permission that is assigned to your account. That is, whether the element is in one of your assigned scopes and whether you meet the minimum security level for that scope.

For more information on user authorization, see the Cisco Prime Network 3.10 Administrator Guide.

The following tables identify the tasks that you can perform:

Table 13-1 identifies the tasks that you can perform if a selected element is not in one of your assigned scopes.

Table 13-2 identifies the tasks that you can perform if a selected element is in one of your assigned scopes.

By default, users with the Administrator role have access to all managed elements. To change the Administrator user scope, see the topic on device scopes in the Cisco Prime Network 3.10 Administrator Guide.

Viewing Resilient Ethernet Protocol Properties

Cisco Resilient Ethernet Protocol (REP) technology is implemented on Cisco Carrier Ethernet switches and intelligent service edge routers. REP is a segment protocol, and a REP segment is a chain of ports connected to each other and configured with the same segment identifier. Each end of a segment terminates on an edge switch. The port where the segment terminates is called the edge port.

Cisco Prime Network discovers and displays REP Segments (identified by a REP segment identifier that is locally configured on the network element) along with Global REP configuration details.

You can also view the REP port roles (open, alternate, and failed) in the Cisco Prime Network Vision map. The REP port role is displayed as a tool-tip between the REP enabled trunk ports in the Ethernet links. Using the Cisco Prime Network Vision map, you can identify if the segment is open or closed.

The map displays the forwarding direction (REP port roles) along the Physical links within VLAN overlays. It also displays the forwarding direction along the VLAN links among the switching elements within the VLAN logical domain topology.

REP implementation supports the following faults:

A REP Port Role change to Failed service event will be generated when a REP port role is change from Alternate or Open to Failed.

A REP Port Role change to OK clearing service event will be generated when a REP port role is change from Failed to Alternate or Open.

Correlation to these service events to physical layer events (for example Link down or Port down) is also performed.

You can view REP properties in logical inventory.


Step 1 In Prime Network Vision, double-click the device configured for REP.

Step 2 In the inventory window, choose Logical Inventory > Resilient Ethernet Protocol.

Figure 13-4 shows an example of REP in logical inventory.

Configured Load Balancing Blocked VLANs

List of VLANs configured to be blocked at this port for REP VLAN load balancing.

Preemptive Timer

Amount of time, in seconds, that REP waits before triggering preemption after the segment is complete. The entry can range from 0 to 300, or be Disabled.

The value Disabled indicates that no time delay is configured, and that the preemption occurs manually.

This property applies only to REP primary edge ports.

LSL Ageout Timer

Using the Link Status Layer (LSL) age-out timer, the amount of time, in milliseconds, that the REP interface remains up without receiving a hello from a neighbor.

Remote Device MAC

MAC address of the neighbor bridge that this port is connected to on this segment. This value can be null.



The following topics describe how to view REP properties related to VLANs:

VLAN domain views and overlays—See Viewing REP Information in VLAN Domain Views and VLAN Overlays.

VLAN service link properties—See Viewing REP Properties for VLAN Service Links.

Viewing HSRP Properties

Hot Standby Router Protocol (HSRP) is a protocol that provides backup to a router in case of failure. Using HSRP, several routers are connected to the same Ethernet network segment and work together to present the appearance of a single virtual router. The routers share the same IP and MAC addresses; therefore in the event of failure of one router, the hosts on the LAN will be able to continue forwarding packets to a consistent IP and MAC address.

HSRP groups are configured on IP interfaces. An IP interface is modeled by the VNE through the IPInterface DC. The IPInterface DC maintains the HSRP related information by the use of HSRP group entries. Ethernet DCs, which are used to model Ethernet ports, maintain MAC addresses of the HSRP groups.

To view HSRP properties:


Step 1 Double-click the required element in Prime Network Vision.

Step 2 In logical inventory, choose Logical Inventory > Routing Entities > Routing Entity.

Step 3 In the IP Interfaces tab, double-click the required interface to view the IP interface properties. If HSRP is configured on the IP interface, the HSRP Group tab is displayed as shown in Figure 13-6.

State

State of the HSRP group: Active or Standby.

Virtual IP Address

Virtual IP address assigned to the active router.

Virtual MAC Address

Virtual MAC address assigned to the active router.



Viewing Access Gateway Properties

In an access network, an access gateway configuration ensures loop-free connectivity in the event of various failures by sending statically configured bridge protocol data units (BPDUs) toward the access network. Using statically configured BPDUs enables the gateway device to act appropriately when notified of the following topology changes:

Failure of a link in the access network.

Failure of a link between the access network and the gateway device.

Failure of an access device.

Failure of a gateway device.

To view access gateway properties:


Step 1 Double-click the element configured for access gateway.

Step 2 In the inventory window, choose Logical Inventory > Access Gateway > access-gateway. The group name is appended by either MSTAG or REPAG, indicating the group type Multiple Spanning Tree Access Gateway or Resilient Ethernet Protocol Access Gateway.

Working with Ethernet Link Aggregation Groups   

Ethernet link aggregation groups (LAGs) provide the ability to treat multiple switch ports as one switch port. The port groups act as a single logical port for high-bandwidth connections between two network elements. A single link aggregation group balances the traffic load across the links in the channel.

LAG links are discovered automatically for devices that support LAG technology and use VNEs that model Link Aggregation Control Protocol (LACP) attributes.

You can create static links between Ethernet LAGs by choosing a LAG and the desired port channel for the A or Z side as described in Adding Static Links.

If a physical link within the link aggregation group fails, the following actions occur:

Traffic that was previously carried over the failed link is moved to the remaining links.

Most protocols operate over single ports or aggregated switch ports and do not recognize the physical ports within the port group.

An aggregation service alarm is generated.

The aggregation service alarm indicates the percentage of links within the aggregation that have failed. For example, if an Ethernet link aggregation group contains four Ethernet links and one fails, the aggregation service alarm indicates that 25% of the links are down.

Viewing Ethernet LAG Properties


Note Cisco CRS devices must be configured to receive SNMP traps in order to view Ethernet LAG properties. For more information on required SNMP settings, see the Cisco Prime Network 3.10 Administrator Guide.

If the VLAN EFP element represents a configuration, such as a service instance on a Cisco 7600 device or an enhanced port on a Cisco ASR 9000 device, and is associated directly with a network VLAN or a bridge domain switching entity, the severity and ticket badges are based on the underlying service instance or enhanced port configuration.

Figure 13-16 shows an example of a ticket badge based on a service instance.

Figure 13-16 EFP Severity and Ticket Badges Based on Underlying Service Instance

If the Ethernet flow point element represents a VLAN interface for a regular switch port, the severity and ticket badges are based on the corresponding port, as shown in Figure 13-17.

Figure 13-17 EFP Severity and Ticket Badges Based on Corresponding Port

Viewing EVC Service Properties

Certain EVC service properties are configured as port attributes. These attributes determine the degree of service transparency and protect the service provider's network from protocol control traffic. Prime Network Vision discovers these key EVC service properties and displays this information in physical inventory for the following devices:

Cisco ME3400- and Cisco ME3400E-series devices running Cisco IOS versions 12.2(52)SE to 12.2(54)SE.

Cisco 3750 Metro devices running Cisco IOS versions 12.2(52)SE to 12.2(54)SE.

Shared Switching Entities and EVC Service View

Some switching entities that Prime Network Vision discovers are concurrently part of a network VLAN and VPLS/EoMPLS instance. These switching entities are referred to as shared switching entities.

Prime Network Vision displays the switching entity information for shared switching entities only under the VPLS instances in the EVC service view.

To view EVC port-related properties for the supported devices and software versions:


Step 1 In Prime Network Vision, double-click the required device.

Step 2 In the inventory window, choose Physical Inventory > Chassis > module > port.

Viewing and Renaming Ethernet Flow Domains

An Ethernet flow domain represents an Ethernet access domain. The Ethernet flow domain holds all network elements between the CE (inclusive, if managed by the SP), up to the SP core (exclusive). This includes CE, access, aggregation, and distribution network elements.

An Ethernet flow domain can have no N-PEs (flat VLAN) or one or more N-PEs (N-PE redundancy configuration). The Ethernet flow domain is defined using physical connectivity at the port level, and not at the network element level. STP is used to mark the root bridge, root or blocked ports, and blocked VLAN links.

To view Ethernet flow domains:


Step 1 In Prime Network Vision, choose Network Inventory > Ethernet Flow Domains.

The Ethernet Flow Domain List window is displayed with the domain name, the system-defined domain name, and a brief description for each Ethernet flow domain as shown in Figure 13-19.

Figure 13-19 Ethernet Flow Domain List Properties Window

Understanding VLAN and EFD Discovery

When you start the Prime Network gateway the first time, Prime Network Vision waits for two topology cycles to complete before discovering new VLANs, VLAN associations, and EFDs. The default configured time for two topology cycles to complete is one hour, but might be configured for longer periods of time on large setups. This delay allows the system to stabilize, and provides the time needed to model devices and discover links.

During this delay, Prime Network Vision does not add VNEs or apply updates to existing VLANs or EFDs.

After the initial delay has passed, Prime Network Vision discovers new VLANs, VLAN associations, and EFDs, applies updates to existing VLANs, VLAN associations, and EFDs, and updates the database accordingly.

When you restart the gateway, Prime Network Vision uses the persisted topology information instead of waiting two topology cycles, thus improving the discovery time for new VLANs, VLAN associations, and EFDs.

Understanding VLAN Elements

The following concepts are important to understand when working with the representation of edge EFPs inside VLANs:

VLANs

Prime Network Vision discovers and allows you to display maps with a network-level view of VLANs.

In Prime Network, a VLAN entity consists of one or more switching entities and the corresponding EFP elements.

A network VLAN represents the virtual LAN. The network VLAN holds its contained switching entities and can be associated to a customer. The network VLAN also holds the Ethernet flow points that are part of the network VLAN but not part of any switching entity. For example, a port that tags ingress flows after which the flow moves to a different VLAN.

Switching Entities

A switching entity represents a device-level Layer 2 forwarding entity (such as a VLAN or bridge domain) that participates in a network VLAN. A switching entity is associated to a network VLAN according to its relationship to the same Ethernet Flow Domain (EFD) and the VLAN identifier.

If you right-click a switching entity in Prime Network Vision and then choose Inventory, the inventory window is displayed with the corresponding bridge selected in Logical Inventory.

A switching entity typically contains EFP elements.

Ethernet Flow Points

An Ethernet flow point (EFP) can represent a port that is configured for participation in a specific VLAN.

If you right-click an EFP in Prime Network Vision and then choose Inventory, the inventory window is displayed with the corresponding port selected in Physical Inventory.

EFPs that are located in a switching entity represent Ethernet ports that are configured as switch ports (in either Access, Trunk, or Dot1Q tunnel mode).

Figure 13-21 shows an example of EFPs configured as switch ports in Prime Network Vision.

Figure 13-21 EFPs Configured as Switch Ports

EFPs that are located directly inside a VLAN represent one of the following:

Termination point EFPs—Ethernet ports that are at the edge of a Layer 2 domain flow, such as a VLAN, on which traffic enters a Layer 3 domain or a different Layer 2 domain, such as EoMPLS. These ports are found on such devices as the Cisco 7600 series, Cisco GSR, and Cisco ASR 9000 series devices.

These EFPs are typically connected to a switching entity inside the VLAN by a VLAN link, as shown in Figure 13-22.

Figure 13-22 Termination Point EFP Inside a VLAN

Edge EFPs—A subset of EFPs that exist inside a switching entity but that are not connected to other EFPs and that represent edge EFPs in the context of the VLAN.

In Prime Network Vision, edge EFPs are displayed directly under the VLAN at the same level as their switching entities and are connected to their corresponding switching entities by a dotted link, as shown in Figure 13-23.

Figure 13-23 Edge EFP Inside a VLAN

An edge EFP can be displayed both inside and outside of its switching entity, as shown (highlighted with a red outline) in Figure 13-24:

Figure 13-24 Edge EFPs Displayed Inside and Outside of Switching Entities

You can delete EFPs and switching entities that have a reconciliation icon by right-clicking them and choosing Delete. After all switching entities and EFPs are deleted from a network VLAN, the empty network VLAN is automatically deleted from Prime Network Vision after a few minutes.

Switching Entities Containing Termination Points

For some devices, such as Cisco 7600 series, Cisco GSR, and Cisco ASR 9000 series devices, the related switching entities can contain Ethernet flow point elements that serve as termination points on different network VLANs. If a single map contains both the switching entities and the network VLANs, a link is displayed between them.

Adding VLANs to a Map

You can add VLANs to a map if the VLANs were previously discovered by Prime Network Vision and are not currently displayed in the map.


Note Adding VLANs affects other users if they are working with the same map.


To add VLANs to a map:


Step 1 In Prime Network Vision, display the map to which you want to add the VLANs.

Step 2 Choose File > Add to Map > VLAN. The Add VLAN to map dialog box is displayed as shown in Figure 13-25.

Figure 13-25 Add VLAN Dialog Box

Step 3 In the Add VLAN dialog box, do either of the following:

Choose a search category, enter a search string, then click Go to narrow the VLAN display to a range of VLANs or a specific VLAN.

The search condition is "contains." Search strings are case-insensitive. For example, if you choose the Name category and enter "net," Prime Network Vision displays VLANs that have "net" anywhere in their names. The string "net" can be at the beginning, the middle, or end of the name, such as Ethernet.

Choose Show All to display all the VLANs.

Step 4 Select the VLANs that you want to add to the map.


Tip Press Shift or Ctrl to choose multiple adjoining or nonconsecutive VLANs.


Step 5 Click OK.

The VLANs are displayed in the Prime Network Vision content pane as shown in Figure 13-26.

Any tickets that apply to the VLANs are displayed in the ticket pane.

Removing VLANs from a Map

You can remove one or more VLANs from the current map. This change does not affect other maps. Removing a VLAN from a map does not remove it from the Prime Network database. You can add the VLAN to the map at any time.

When removing VLANs from maps, keep the following in mind:

Removing a VLAN affects other users who are working with the same map view.

This option does not change the business configuration or database.

You cannot remove virtual routers or sites from the map without removing the VLAN.

To remove a VLAN, in the Prime Network Vision navigation pane or map view, right-click the VLAN and choose Remove from Map.

The VLAN is removed from the navigation pane and map view along with all VLAN elements such as connected CE devices. Remote VLANs (extranets) are not removed.

Viewing VLAN Mappings

VLAN mapping, or VLAN ID translation, is used to map customer VLANs to service provider VLANs. VLAN mapping is configured on the ports that are connected to the service provider network. VLAN mapping acts as a filter on these ports without affecting the internal operation of the switch or the customer VLANs.

If a customer wants to use a VLAN number in a reserved range, VLAN mapping can be used to overlap customer VLANs by encapsulating the customer traffic in IEEE 802.1Q tunnels.

To view VLAN mappings:


Step 1 In Prime Network Vision, double-click the device with VLAN mappings configured.

Step 2 In the inventory window, choose Physical Inventory > Chassis > slot port.

Step 3 Click VLAN Mappings next to the Subinterfaces tab in the lower portion of the content pane.

The VLAN Mappings tab is displayed as shown in Figure 13-27.

Viewing Associated Network VLAN Service Links and VLAN Mapping Properties

After you add an associated network VLAN, you can:

View the associated network VLAN service links in Prime Network Vision in the thumbnail view.

View VLAN mapping properties in the Link Properties window.

To view associated network VLAN service links and VLAN mapping properties:


Step 1 Select the required network VLAN in the map view.

Step 2 Right-click the VLAN, then choose Show Thumbnail.

Figure 13-29 shows an example of a network VLAN in a thumbnail.

The VLAN service links are displayed as lines between the associated network VLANs. The links represent the connections between the Ethernet flow points that are part of each network VLAN.

Step 3 To view additional information, right-click a link, and choose Properties.

The Link Properties window is displayed as shown in Figure 13-30.

If VLAN tag manipulation is configured on the link, the VLAN Mapping Properties area in the Link Properties window displays the relevant information. For example, in Figure 13-30, the VLAN Mapping Properties area shows that a one-to-one VLAN mapping for VLAN tag 1709 to VLAN tag 709 is configured on GigabitEthernet1/1/1 on c7-sw8 on the egress direction.

Figure 13-30 VLAN Mapping Properties in Link Properties Window

Viewing REP Properties for VLAN Service Links

Viewing STP Properties for VLAN Service Links

Viewing VLAN Links Between VLAN Elements and Devices

If a Prime Network Vision map contains a VLAN and the network element on which the VLAN is configured, along with EFPs, switching entities, or network VLANs, you might see what appear to be multiple associations between the logical and physical entities. Actually, however, you are seeing other views of the original VLAN link.

For example, assume that you have the following situation, as shown in Figure 13-31 and described in the following paragraphs.

Figure 13-31 VLAN Elements and Devices in Prime Network Vision

The elements are configured as follows:

Port GigabitEthernet1/1/2 on element c7-sw10 is connected to port GigabitEthernet1/1/2 on element c7-sw8 by an Ethernet topology link.

Port GigabitEthernet1/1/2 on element c7-sw10 is a trunk port associated with VLAN-1704 which is configured on element c7-sw10.

Port GigabitEthernet1/1/2 on element c7-sw8 is a trunk port associated with VLAN-704 which is configured on element c7-sw8.

Port GigabitEthernet1/1/2 on element c7-sw8 has a VLAN mapping to tunnel VLAN-1704 (C-VLAN) in VLAN-704 (SP-VLAN).

In this example, VLAN discovery identified two network VLANs: VLAN-1704 and VLAN-704. Each of these network VLANs contains a switching entity and an EFP that represent the connected ports, GigabitEthernet1/1/2@c7-sw10 and GigabitEthernet1/1/2@c7-sw8, respectively.

The four links in the map are identified in Figure 13-32 and described in the following table.

Figure 13-32 Links Between VLAN Elements and Devices

1

The Ethernet topological link between port GigabitEthernet1/1/2 on VNE c7-sw10 and GigabitEthernet1/1/2 on VNE c7-sw8.

2

The VLAN link between GigabitEthernet1/1/2@c7-sw10 EFP and GigabitEthernet1/1/2@c7-sw8 EFP.

3

Another view of the VLAN link (link 2), shown as a link between GigabitEthernet1/1/2@c7-sw10 EFP and GigabitEthernet1/1/2@c7-sw8 EFP.

4

Another view of the VLAN link (link 2), shown as a link between GigabitEthernet1/1/2@c7-sw10 EFP and GigabitEthernet1/1/2@c7-sw8 EFP.


The key point is that a link between a VNE and EFP, switching entity, or network VLAN does not represent an association between the VNE and the logical element. Such a link is simply another view of the VLAN link.

If the thumbnail view is closed, instead of a link between the VNE and EFP, you will see a link between the VNE and the switching entity or network VLAN.

Applying VLAN Overlays

You can create an overlay of a specific VLAN on top of the physical network elements displayed in a map view. The overlay highlights the network elements and links that the selected VLAN and its associated VLANs traverse. Network elements and links that are not part of the VLAN are dimmed in the map view.

The VLAN overlay is a snapshot of the network to help you visualize the network elements and links connected to a VLAN. The overlay displays STP and REP link and port information.

If you select a network VLAN that is associated with other VLANs, the associated VLANs are included in the overlay.

The VLAN service overlay allows you to isolate the parts of a network that are being used by a particular service. This information can then be used for troubleshooting. For example, the overlay can highlight configuration or design problems when bottlenecks occur and all site interconnections use the same link.

To add a VLAN overlay:


Step 1 Display the network map for which you want to create an overlay in Prime Network Vision.

Step 2 In the toolbar, choose Choose Overlay Type > VLAN.

Step 3 In the Select VLAN Overlay dialog box, do either of the following:

Choose a search category, enter a search string, then click Go to narrow the selection to a set of overlays or a specific overlay.

The search condition is "contains." Search strings are case-insensitive. For example, if you choose the Name category and enter "net," Prime Network Vision displays overlays that have "net" in their names. The string "net" can be at the beginning, middle, or end of the name, such as Ethernet.

Choose Show All to view all overlays.

Step 4 Select an overlay, then click OK.

The network elements and physical links used by the selected VLAN overlay are highlighted in the network map. All other network elements and links are dimmed. The VLAN name is displayed in the title of the window. See Figure 13-33.

Figure 13-33 VLAN Overlay Example



Note The overlay is a snapshot taken at a specific point in time. As a result, the information in the overlay might become stale. To update the overlay, click Refresh the Last Selected Overlay in the toolbar.


Displaying or Hiding VLAN Overlays

After you create a VLAN overlay, you can hide it by clicking Hide Overlay in the toolbar. All previously dimmed network elements and links are displayed. To display the overlay, click Show Overlay.


Note The Overlay icon toggles between Show Overlay and Hide Overlay. When selected, the VLAN overlay is displayed and the Hide Overlay tool is active. When deselected, the VLAN overlay is hidden and the Show Overlay tool is active.


Removing a VLAN Overlay

To remove a VLAN overlay from a map, choose Choose Overlay Type > None in the toolbar. The overlay is removed from the map, and the Show Overlay/Hide Overlay icon is dimmed.

Viewing VLAN Trunk Group Properties

VTP is a Layer 2 multicast messaging protocol that manages the addition, deletion, and renaming of VLANs on a switched network-wide basis.

Prime Network Vision displays VTP information in the logical inventory. VTP information is shown only for Cisco devices that support VTP, and support is provided only for VTP Version 1 and 2. Support for Version 3 is limited to the additional attributes that are supported by the version, such as primary and secondary server. No support is provided for the display of VTP information at the port (trunk) level.

Prime Network Vision shows all VTP modes: Server, Client, Transparent, and Off. For each mode, Prime Network Vision displays the relevant mode information such as VTP domain, VTP mode, VTP version, VLAN trunks, and the trunk encapsulation. Prime Network Vision also displays VTP domain information in a view that includes a list of all switches that are related to these domains, their roles (server, client, and so on), and their VTP properties.

To view VTP properties:


Step 1 In Prime Network Vision, choose Network Inventory > VTP Domains.

Understanding Unassociated Bridges

Some switching entities might not belong to a flow domain, such as a network VLAN, a VPLS instance, or a network pseudowire. These switching entities are referred to as unassociated bridges.

In addition, a switching entity that belongs to a network VLAN is considered an unassociated bridge if it meets both of the following criteria:

The network VLAN contains a null Ethernet flow domain (EFD).

The switching entity contains no switch ports.

Unassociated bridge switching entities can hold Ethernet flow points that serve as termination points on different network VLANs. If these switching entities are added to a map with the relevant VLANs, the links are displayed in the Prime Network Vision map.

Adding Unassociated Bridges

Prime Network Vision enables you to add unassociated bridges to maps and to view their properties.

To add an unassociated bridge to a map:


Step 1 In Prime Network Vision, select the required map or domain.

Step 2 Open the Add Unassociated Bridge dialog box in one of the following ways:

Choose File Add to Map > Unassociated Bridge.

In the toolbar, click Add to Map and choose Unassociated Bridge.

Figure 13-39 shows an example of the Add Unassociated Bridge dialog box.

Figure 13-39 Add Unassociated Bridge Dialog Box

Step 3 In the Add Unassigned Bridge to domain dialog box, select the required bridge and click OK.

The map is refreshed and displays the newly added bridge as shown in Figure 13-40.

Figure 13-40 Unassociated Bridge in Prime Network Vision


Working with Ethernet Flow Point Cross-Connects

Prime Network Vision automatically discovers Ethernet flow point (EFP) cross-connects, also known as locally switched EFPs. Prime Network Vision also identifies changes in already identified EFP cross-connects, such as cross-connect deletions or changes. Cross-connect changes can occur when one side of the cross-connect is removed or replaced.

Prime Network Vision also associates the VLANs that contain the EFPs that are part of the cross-connects. If the cross-connect contains a range EFP, which represents a range of VLANs, and you add the related VLANs to a map, Prime Network Vision displays the links between them and the cross-connect as well.

Prime Network Vision enables you to add EFP cross-connects to maps and to view their properties in inventory, as described in the following topics:

Adding EFP Cross-Connects

Working with VPLS and H-VPLS Instances

Virtual Private LAN Service (VPLS) is a Layer 2 VPN technology that provides Ethernet-based multipoint-to-multipoint communication over MPLS networks. VPLS allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires. The network emulates a LAN switch or bridge by connecting customer LAN segments to create a single bridged Ethernet LAN.

Hierarchical VPLS (H-VPLS) partitions the network into several edge domains that are interconnected using an MPLS core. The edge devices learn only of their local N-PE devices and therefore do not need large routing table support. The H-VPLS architecture provides a flexible architectural model that enables Ethernet multipoint and point-to-point Layer 2 VPN services, as well as Ethernet access to Layer 3 VPN services, enabling service providers to offer multiple services across a single high-speed architecture.

Prime Network Vision discovers the following VPLS-related information from the network and constructs VPLS instances:

VSIs

Pseudowires

EFPs

Switching entities

Working with VPLS and H-VPLS in Prime Network Vision 

Prime Network Vision enables you to:

Monitoring the Pseudowire Headend

A pseudowire (PW) is an emulation of a point-to-point connection over a packet-switching network (PSN). It operates over a uniform packet-based access/aggregation network. The composite L2 AC and the PW segment together form a point-to-point virtual CE-PE link that functions like a traditional CE-PE link technology.

Figure 13-63 displays a typical pseudowrie deployment over core network and Figure 13-64 displays a pseduowire deployment over access network.

Figure 13-63 Pseudowire Deployment Over Core Network

Figure 13-64 Pseudowire Deployment Over Access Network

A pseudowire headend (PW-HE) virtual interface originates as a PW on an access node and terminates on a Layer 3 service instance on the service provider router. For example, a PWHE can originate on the Layer 2 PW feeder node and terminate on a VRF instance on the Cisco CRS Router. You can configure all ingress and egress QoS function on the PW-HE interface, including policing, shaping, queuing, and hierarchical policies.

In other words, the PW-HE is a technology that allows termination of access or aggregation pseduowires into an L2 or L3 domain. It allows us to replace a 2-node solution with a 1-node solution. Without a PW-HE, a L2 PE node must terminate a PW and then handoff the data to a S-PE via an Access Circuit.

The following figure displays the PW-HE interface:

Figure 13-65 PW-HE Interface

The PW-HE interface is treated like any existing L3 interface and operates on one of the following nodes:

Bridged interworking (VC type 5 or 4) node—PW will carry customer Ethernet frames with IP payload. The S-PE device must perform ARP resolution for customer IP addresses learnt over PW-HE, which acts as a broadcast interface.

IP interworking node (VC type 11)—The PW-HE acts as a point-to-point interface. Hence, there will be two types of PW-HE interface-PW-Ether and PW-IW. These PW's can terminate into a VRF or the IP global table on SP-E.

Viewing the PW-HE configuration

To view the PW-HE configuration:


Step 1 Right-click the required device in Prime Network Vision and choose Inventory.

Step 2 In the logical inventory window, choose Logical Inventory > PW-HE. The list of PW-HE interfaces configured in Prime Network are displayed in the content pane.

Working with Ethernet Services

Ethernet services are created when the following business elements are linked to one another:

Network VLAN and bridge domain are linked through a shared EFP.

Network VLAN and VPLS instance are linked through either of the following:

A shared, standalone EFP.

A shared switching entity.

Network VLAN and network pseudowire (single or multi-segment) are linked through either of the following:

A shared, standalone EFP.

A shared switching entity.

VPLS-EoMPLS connected via a shared access pseudowire endpoint.

Network VLAN and cross-connect are connected by a shared EFP.

Network VLAN and service link are connected by a shared EFP.

If a VPLS, network pseudowire, cross-connect, or network VLAN object is not connected to another business element, it resides alone in an Ethernet service.

In releases prior to Prime Network Vision 3.8, EVC multiplex was discovered by means of Ethernet flow point associations. Beginning with Prime Network Vision 3.8, multiplex capabilities were enhanced to distinguish multiplexed services based on the Customer VLAN ID; that is, Prime Network Vision 3.9 is Inner Tag-aware.

As a result, in environments in which service providers have customers with multiplexed services, an EVC can distinguish each service and create its own EVC representation.

Prime Network Vision discovers Ethernet services and enables you to add them to maps, apply overlays, and view their properties. See the following topics for more information:

Viewing IP SLA Responder Service Properties

Cisco IOS Service Level Agreements (SLAs) software allows you to analyze IP service levels for IP applications and services by using active traffic monitoring to measure network performance.

The IP SLA responder is a component embedded in the destination Cisco device that allows the system to anticipate and respond to IP SLAs request packets. The responder provides accurate measurements without requiring dedicated probes. The responder uses the Cisco IOS IP SLAs Control Protocol to provide a mechanism through which it can be notified on which port it should listen and respond.

Two-Way Active Measurement Protocol (TWAMP) defines a standard for measuring round-trip network performance between any two devices that support the protocol.

Prime Network Vision supports IP SLA Responder service on the following devices:

Cisco 3400ME and 3750ME devices running Cisco IOS 12.2(52)SE.

Cisco MWR2941 devices running Cisco CSR 3.2.

To view IP SLA Responder service properties:


Step 1 In Prime Network Vision, double-click the device configured for IP SLA Responder service.

Viewing IS-IS Properties

Intermediate System-to-Intermediate System (IS-IS) protocol is a routing protocol developed by the ISO. It is a link-state protocol where IS routers exchange routing information based on a single metric to determine network topology. It behaves in a manner similar to OSPF in the TCP/IP network.

IS-IS networks contain end systems, intermediate systems, areas, and domains. End systems are user devices. Intermediate systems are routers. Routers are organized into local groups called areas, and areas are grouped into a domain. For configuring IS-IS, see Configuring IS-IS.

To view IS-IS properties:


Step 1 In Prime Network Vision, double-click the device configured for IS-IS.

Step 2 In the inventory window, choose Logical Inventory > IS-IS > System.

Configuring IS-IS

In order to enable IS-IS for IP on a Cisco router and have it exchange routing information with other IS-IS enabled routers, you must perform these two tasks:

Enable the IS-IS process and assign area

Enable IS-IS for IP routing on an interface

You can configure the router to act as a Level 1 (intra-area) router, as Level 1-2 (both a Level 1 router and a Level 2 router), or as Level 2 (an inter-area router only).

The IS-IS commands helps you to configure the IS-IS on a Cisco router. These commands can be launched from the logical inventory. Before executing any commands, you can preview them and view the results. If desired, you can also schedule the commands.

The table below lists the IS-IS configuration commands and the ISIS supported network elements.
