Step 7 Click Return to Logs to specify another log to view.

Ping

Ping is the way ISC monitors the VPN connectivity, that is verify the connectivity among various edge devices comprising the VPN. To achieve this, you can perform a series of pings among these devices. Ping has the following benefits:

•Ping is service independent and therefore can be used for functional auditing of MPLS applications.

•Ping can establish whether a service is working without doing a functional audit for that service.

•Ping can be used to verify IPv4 connectivity among CPEs prior to VPN or Firewall- This feature is NOT SUPPORTED in this release. - service deployment.

•Ping fits well with Firewall service in conjunction with a VPN service for ensuring the firewall service did not break the VPN service.- This feature is NOT SUPPORTED in this release. -

However, Ping does not do the following:

•Ping does not work in environments where ICMP traffic is blocked, for example, in an Cisco IOS router with an access-list denying all ICMP traffic or a PIX firewall which by default does not permit ICMP.

•Ping can only inform you that there is a connectivity problem. It does not offer any service-specific information. The connectivity problem can be due to many reasons, such as device failure, misconfiguration, and so on, which ping cannot distinguish.

•Only the immediate subnet behind the router's customer-facing (also, inside or nonsecured) interface is supported. Campus subnets cannot be supported.

The Ping GUI supports all possible pings for MPLS service requests.

This section explains how to ping MPLS service requests.

After you navigate Monitoring > Ping, you receive a window as shown in.Figure 7-11, "Services."

Figure 7-11 Services

From here you can use the Show Services with drop-down menu to select:

•Job ID

•Customer Name

•VPN Name

•State

•Description

Then for matching, enter the beginning characters of the names you want to match followed by *.

Then before clicking Find, from of type select MPLS or IPsec (This feature is NOT SUPPORTED in this release). -and proceed as follows:

•MPLS explains the flow after choosing the type MPLS.

•IPsec explains the flow after choosing the type IPsec.- This feature is NOT SUPPORTED in this release. -

Note At the bottom of many windows, you can change the number of rows shown on this window in Rows per page. Click the drop-down menu and you can select 5, 10, 20, 30, 40, or All.

Note At the bottom of many windows you can click the Auto Refresh button to automatically refresh after n seconds, where n is the refresh rate set in DCPL, or you can unclick this button and not automatically refresh.

MPLS

After you navigate Monitoring > Ping and select MPLS as the type, follow these steps:

Step 1 Select the check box next to each row for which you want to configure ping parameters or select the check box in the heading row to select all the rows.

Step 2 Click the Configure Ping Parameters button which becomes enabled. A window as shown in Figure 7-12, "MPLS Parameters," appears.

Figure 7-12 MPLS Parameters

Fill in the following and then click Start Ping:

•Ping Type—Do PE to CE When this radio button is chosen, a VRF ping occurs for all PE CE pairs that form an MPLS VPN link. The IP addresses taken for this ping are the link end-point addresses. For example, assume that an MPLS service request has two linked PE1<>CE1 and PE2<>CE2. Then this selection initiates four VRF pings: (PE1, CE1), (PE2, CE2), (PE1, CE2), and (PE2, CE1). When this selection is chosen, then after you click Start MPLS Ping, you go directly to Step 6 and receive a result page.

•Ping Type—Do CE to CE ping When this radio button is chosen, a ping occurs between all CEs that make the end-point in the service request. When this selection is chosen, then after you click Start MPLS Ping, proceed to Step 3.

•Two-way Ping (default: unavailable and deselected) This check box is only available when you select Do CE to CE ping. When a ping occurs from device1 to device2 and this check box is selected, then a ping from device2 to device1 also occurs.

•Packet Repeat count (valid values: 5 - 1000) (default: 5) This value indicates how many ICMP packets to use for a ping.

•Datagram size (valid values: 36-18024) (default: 100) This value is the packet size of ICMP used for pinging.

Step 3 For Do CE to CE ping, you proceed to a window as shown in Figure 7-13, "MPLS CE Selection."

Figure 7-13 MPLS CE Selection

Step 4 Select the check box next to each row for which you want to select a CE or select the check box in the heading row to select all the rows.

Step 5 Click the Start MPLS CE Ping button which becomes enabled.

Step 6 You receive a results window as shown in Figure 7-14, "MPLS Ping Test Results.

Step 7 The buttons at the bottom of the window are as follows:

•Redo Ping When you click this button, you restart all the pings. The parameters used are the same as those specified in the last request.

•View Job Logs When you click this button, you receive logs of all the ISC jobs created for doing ping. The ping application creates one job per selected service request.

•Auto Refresh If this check box is selected, a result refreshes every n seconds, where n is defined in DCPL as the refresh rate.

•Refresh To selectively refresh, turn off the Auto Refresh button and click this button whenever you want to update the results.

•Close Click this button to close the current ping request. You return to the Monitoring page.

Note Any column heading in blue indicates that by clicking that column header, you can sort on that column.

Step 8 Click Close and you are finished with this Ping session.

IPsec

- This feature is NOT SUPPORTED in this release. -

After you navigate Monitoring > Ping and select IPsec as the type, follow these steps:

Step 1 Select the check box next to each row for which you want to configure ping parameters or select the check box in the heading row to select all the rows.

Step 2 Click the Configure Ping Parameters button which becomes enabled. A window as shown in Figure 7-15, "IPsec Parameters," appears.

Figure 7-15 IPsec Parameters

Fill in the following and then click Start Ping. If you select Select subset of devices to ping, you proceed to Step 3. If not, you proceed to Step 6.

•Using IPsec tunnels (required) (default: Ping inside IPsec tunnels) If you select the Ping inside IPsec tunnels radio button, you use nonsecure interfaces for ping. If you select the Ping outside IPsec tunnels radio button, you use secure interfaces for the ping.

•Mirror Ping (default: deselected) When a ping occurs from device1 to device2 and this check box is selected, then a ping from device2 to device1 also occurs.

•Full mesh ping (default: deselected) In a scenario like DMVPN, where spokes of a hub and spoke service request can talk to each other without going through the hub, you might be required to do a full-mesh ping, that is ping as though the service request is full-mesh. In this case, select this check box.

•Select subset of devices to ping (default: deselected) When this check box is selected, you receive the ability to select the pings you require rather than pinging all the choices.

Note Full mesh ping and Select subset of devices to ping can be used in conjunction to verify that the DMVPN is working. For example, for a hub and spoke service request with three spokes, if spoke1 and spoke2 are connected, you are interested in following pings: (hub, spoke1), (hub, spoke2), (hub, spoke3), and (spoke1,spoke2). You can select both check boxes Full mesh ping and Select subset of devices to ping. Then on the CE selection page you receive all possible ping combinations between a hub and four spokes. You can select the four required pings and view the result.

•Packet repeat count (valid values: 5 - 1000) (default: 5) This value indicates how many ICMP packets to use for a ping.

•Datagram size (valid values: 36-18024) (default: 100) This value is the packet size of ICMP used for pinging.

Step 3 If you selected Select subset of devices to ping, you receive a window as shown in Figure 7-16, "IPsec CE Selection."

Step 4 Select the check box next to each row for which you want to select a CE or select the check box in the heading row to select all the rows.

Step 5 Click the Start IPsec CE Ping button which becomes enabled.

Step 6 You receive a results window as shown in Figure 7-17, "IPsec Ping Test Results.

Figure 7-17 IPsec Ping Test Results

Step 7 The buttons at the bottom of the window are as follows:

•Redo Ping When you click this button, you restart all the pings. The parameters used are the same as those specified in the last request.

•View Job Logs When you click this button, you receive logs of all the ISC jobs created for doing ping. The ping application creates one job per selected service request.

•Auto Refresh If this check box is selected, a result refreshes every n seconds, where n is defined in DCPL as the refresh rate.

•Refresh To selectively refresh, turn off the Auto Refresh button and click this button whenever you want to update the results.

•Close Click this button to close the current ping request. You return to the Monitoring page.

Note Any column heading in blue indicates that by clicking that column header, you can sort on that column.

Step 8 Click Close and you are finished with this Ping session.

SLA

A service-level agreement (SLA) defines a level of service provided by a service provider to any customer. Performance is monitored through the SLA server. ISC monitors the service-related performance criteria by provisioning, collecting, and monitoring SLAs on Cisco IOS routers that support the Service Assurance Agent (SA Agent) devices. To provision the SLAs and to collect statistics for each SLA, the data collection task requires minimal user input.

The SLA collection task collects the relevant performance data, stores it persistently, aggregates it, and presents useful reports. The SLA collection task collects from the SA Agent MIB on devices. ISC leverages the SA Agent MIB to monitor SLA performance on a 24 x 7 basis. Using the MIB, you can monitor network traffic for the popular protocols: Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), File Transfer Protocol (FTP), Hyper text Transfer Protocol (HTTP), Internet Control Message Protocol Echo (ICMP Echo), Jitter (voice jitter), Transmission Control Protocol Connect (TCP Connect), and User Datagram Protocol Echo (UDP Echo).

Note SLA uses the embedded Sybase database, independent of whether you choose Oracle as your database.

Note The SLA operations Create, Delete, Enable Probes, Disable Probes, Enable Traps, and Disable Traps automatically result in the creation of a task, which executes the actual operation. You can view the status of the task by navigating Monitoring > Task Manager > Logs.

This section explains how to configure SLA probes, collect SLA data, and view SLA reports about these SLA probes.

Before you navigate Monitoring > SLA, implement the setup procedures in the "Setup Prior to Using SLA" section."

Then navigate Monitoring > SLA and you can select one of the following:

•Probes is the default selection.

•Reports

Setup Prior to Using SLA

SLA is an SNMP activity. Be sure SNMP is enabled and the SNMP settings on the router match the settings in the repository.

When creating an SLA From MPLS CPE, From MPLS PE, or From IPsec CPE (This feature is NOT SUPPORTED in this release.), the service requests associated with the devices must be in the Deployed state.

Probes

When you navigate Monitoring > SLA > Probes, you receive a window as shown in Figure 7-18, "SLA Probes."

Figure 7-18 SLA Probes

The default button that is enabled is Create and from the Create drop-down menu, you can choose to create SLA probes From Any SA Agent Device(s); From MPLS CPE; From MPLS PE; or From IPsec CPE (This feature is NOT SUPPORTED in this release.). However, if you select one or more existing probes by clicking the row(s) of existing probe(s), to select the specific probe(s), or you click the box in the header row, to select all the probes, then you have access to the other buttons, Details, Delete, Enable, and Disable. For Enable and Disable, the drop-down menu contains options to enable or disable SLA Probes and SLA Traps.

At the top of this window, for Show Probes with Source Device Name matching you can enter the beginning characters of the names you want to match followed by *; then for of Type, you can keep the default of *, which searches for all the protocol types, or you can select the drop-down menu to select a specific protocol type; and then click Find.

At the bottom of the window, you can change the number of rows shown on this window in Rows per page. Click the drop-down menu and you can select 5, 10, 20, 30, 40, or All.

The explanations of the buttons and subsequent drop-down menus is given as follows:

•Create From Any SA Agent Device(s) This section explains how to create probes from any SA Agent device(s).

•Create from MPLS CPE This section explains how to create probes from an MPLS CPE.

•Create From MPLS PE or MVRF-CE This section explains how to create probes from an MPLS PE.

•Create from IPsec CPE - This feature is NOT SUPPORTED in this release. -

•Protocols This section is common Probes information for each of the Create paths.

•Details This section gives details about a specified probe or all the probes.

•Delete This section explains how to delete a probe.

•Enable Probes This section explains how to enable the Status and move it from Created to Active.

•Enable Traps This section explains how to enable traps.

•Disable Probes This section explains how to disable the Status and move it from Active to Created.

•Disable Traps This sections explains how to disable traps.

Create From Any SA Agent Device(s)

When you navigate Monitoring > SLA > Probes, the default is the Probes page with only the Create button enabled. From the Create drop-down menu, you can select From Any SA Agent Device(s), as shown in Figure 7-19, "SLA Probes > Create > From Any SA Agent Device(s)."

Note IP connectivity must be available between the SA Agent devices.

Figure 7-19 SLA Probes > Create > From Any SA Agent Device(s)

You then proceed through the following steps:

Step 1 The first window to appear is as shown in Figure 7-20, "SLA Common Parameters."

Figure 7-20 SLA Common Parameters

Accept the defaults or change the information in the fields of the common SLA parameters, as follows, and then click Next:

•SLA Life (required) is the number of seconds that the probe is active (with the maximum value of a 32-bit integer in seconds). If the value is set to -1, the typical and default value, the probe is active forever.

•Threshold (required) is an integer that defines the threshold limit in milliseconds. When this threshold is exceeded and traps are enabled, a trap is sent. The maximum value is the maximum value of a 32-bit integer. If the SA Agent operation time exceeds this limit, the threshold violation is recorded by the SA Agent. The value for Threshold must not exceed the value for Timeout. The default value is 5000.

•Timeout (required) is the duration in milliseconds to wait for an SA Agent operation completion. The value for Timeout must be less than or equal to the value for Frequency and greater than or equal to the value for Threshold. The default value is 5000

•Frequency (0 - 604800) (required) is the duration in seconds between initiating each SA Agent operation. The value for Frequency must be greater than or equal to the value for Timeout. The default value is 60.

•TOS Category (default: Precedence) If you select the Precedence radio button for TOS Category, you have one set of type of service (TOS) values. If you select the DSCP radio button for TOS Category, you have a different set of TOS values.

•TOS (required) is an integer. The range and meanings of the values depend on whether the radio button in the TOS Category is set to Precedence (values: 0 to 7) or DSCP (values: 0 to 63).

–When the TOS Category is set to Precedence, the valid values are 0 to 7. These values represent the three most significant bits of the ToS field in an IP header. The default value is 0. The meanings of the Precedence values are specified in Table 7-1, "Meanings of Precedence Values."

Note Type of Service does not apply to the DNS and DHCP types of SLA probes. ISC ignores any ToS value set for these two types of SLA probes. For example, if you first select a ToS value of 5, then select the DNS, DHCP, and ICMP Echo protocols for an SLA probe, ISC applies the selected ToS value to the ICMP Echo probe only.

–When the TOS Category is set to DSCP, the valid values are 0 to 63. These values represent the six most significant bits of this ToS field in an IP header. The default value is 0. The interpretation of these TOS values is user specified.

Note ISC maps the 0 - 7 PRECEDENCE values to the three most significant ToS bits by left-shifting the value by five positions. Similarly, the 0 - 63 DSCP values are left-shifted by two positions.

•Keep History (default: deselected) If you select the Keep History check box, you indicate to keep the recent History Table on the router. Specifically, it is kept in the SA Agent MIB that keeps the raw round-trip time (RTT) SLA measurement. This selection also enables you to indicate the Number of Buckets of raw history data to keep. If you leave the default of a deselected check box for Keep History, no raw history data is kept. Keep History is not supported for HTTP and Jitter.

•Number of Buckets (1 - 60) (required) The default is 15 when the Keep History box is selected. The range is 1 to 60 and indicates the number of most recent raw data entries to be kept in the raw history data. When the specified Number of Buckets is surpassed, removal of buckets starts with the oldest bucket to keep only the number of raw data entries specified.

•Enable Traps (default: deselected, which means No) If you select the Enable Traps box, the created SLA is configured to send three types of traps. This selection also enables you to indicate the Falling Threshold. If you leave the Enable Traps box deselected, the traps are disabled on the SLAs created in this task.

•Falling Threshold (1 - Threshold) (required) The default is 3000 in milliseconds when the Enable Traps box is selected. The range is 1 to the Threshold value in milliseconds. When traps are enabled and the delay meets the specified number of milliseconds, a trap is sent.

Step 2 The next window to appear is as shown in Figure 7-21, "SLA Source Devices."

You then proceed through the following steps:

Step 1 The first window to appear is as shown in Figure 7-25, "SLA Common Parameters."

Figure 7-25 SLA Common Parameters

Accept the defaults or change the information in the fields of the common SLA parameters, as follows, and then click Next:

•SLA Life (required) is the number of seconds that the probe is active (with the maximum value of a 32-bit integer in seconds). If the value is set to -1, the typical and default value, the probe is active forever.

•Threshold (required) is an integer that defines the threshold limit in milliseconds. When this threshold is exceeded and traps are enabled, a trap is sent. The maximum value is the maximum value of a 32-bit integer. If the SA Agent operation time exceeds this limit, the threshold violation is recorded by the SA Agent. The value for Threshold must not exceed the value for Timeout. The default value is 5000.

•Timeout (required) is the duration in milliseconds to wait for an SA Agent operation completion. The value for Timeout must be less than or equal to the value for Frequency and greater than or equal to the value for Threshold. The default value is 5000

•Frequency (0 - 604800) (required) is the duration in seconds between initiating each SA Agent operation. The value for Frequency must be greater than or equal to the value for Timeout. The default value is 60.

•TOS Category (default: Precedence) If you select the Precedence radio button for TOS Category, you have one set of type of service (TOS) values. If you select the DSCP radio button for TOS Category, you have a different set of TOS values.

•TOS (required) is an integer. The range and meanings of the values depend on whether the radio button in the TOS Category is set to Precedence (values: 0 to 7) or DSCP (values: 0 to 63).

–When the TOS Category is set to Precedence, the valid values are 0 to 7. These values represent the three most significant bits of the ToS field in an IP header. The default value is 0. The meanings of the Precedence values are specified in Table 7-2, "Meanings of Precedence Values."

Note Type of Service does not apply to the DNS and DHCP types of SLA probes. ISC ignores any ToS value set for these two types of SLA probes. For example, if you first select a ToS value of 5, then select the DNS, DHCP, and ICMP Echo protocols for an SLA probe, ISC applies the selected ToS value to the ICMP Echo probe only.

Figure 7-34 SLA Common Parameters

Accept the defaults or change the information in the fields of the common SLA parameters, as follows, and then click Next:

•SLA Life (required) is the number of seconds that the probe is active (with the maximum value of a 32-bit integer in seconds). If the value is set to -1, the typical and default value, the probe is active forever.

•Threshold (required) is an integer that defines the threshold limit in milliseconds. When this threshold is exceeded and traps are enabled, a trap is sent. The maximum value is the maximum value of a 32-bit integer. If the SA Agent operation time exceeds this limit, the threshold violation is recorded by the SA Agent. The value for Threshold must not exceed the value for Timeout. The default value is 5000.

•Timeout (required) is the duration in milliseconds to wait for an SA Agent operation completion. The value for Timeout must be less than or equal to the value for Frequency and greater than or equal to the value for Threshold. The default value is 5000

•Frequency (0 - 604800) (required) is the duration in seconds between initiating each SA Agent operation. The value for Frequency must be greater than or equal to the value for Timeout. The default value is 60.

•TOS Category (default: Precedence) If you select the Precedence radio button for TOS Category, you have one set of type of service (TOS) values. If you select the DSCP radio button for TOS Category, you have a different set of TOS values.

•TOS (required) is an integer. The range and meanings of the values depend on whether the radio button in the TOS Category is set to Precedence (values: 0 to 7) or DSCP (values: 0 to 63).

–When the TOS Category is set to Precedence, the valid values are 0 to 7. These values represent the three most significant bits of the ToS field in an IP header. The default value is 0. The meanings of the Precedence values are specified in Table 7-3, "Meanings of Precedence Values."

Note Type of Service does not apply to the DNS and DHCP types of SLA probes. ISC ignores any ToS value set for these two types of SLA probes. For example, if you first select a ToS value of 5, then select the DNS, DHCP, and ICMP Echo protocols for an SLA probe, ISC applies the selected ToS value to the ICMP Echo probe only.

Step 8 From Step 2, if you chose DNS, you receive a window as shown in Figure 7-54, "Protocol DNS."

Figure 7-54 Protocol DNS

Enter the required information as follows, click OK, and then proceed to Step 11.

•Name Server (required) is the string that specifies the IP address of the name server. The address is in dotted IP address format.

•Name to be Resolved (required) is a string that is either the name or the IP address that is to be resolved by the DNS server. If the string is a name, the length is 255 characters. If the string is an IP address, it is in dotted IP address format.

•Request Size (0 - 16384) (required) is a number that represents the number of octets (in bytes) to be placed into the data portion of the packet. The default is 1.

Step 9 From Step 2, if you chose HTTP, you receive a window as shown in Figure 7-55, "Protocol HTTP."

Figure 7-55 Protocol HTTP

Enter the optional and required information as follows, click OK, and then proceed to Step 11.

•Version (default: 1.0) is a string that specifies the version of the HTTP server. Do not change this. ISC only supports version 1.0.

•URL (required) is a string that represents the URL to which an HTTP probe should communicate, HTTPServerName[/directory]/filename or HTTPServerAddress[/directory]/filename (for example: http://www.cisco.com/index.html or http://209.165.201.22/index.html). If you specify the HTTPServerName, the Name Server is required. If you specify the HTTPServerAddress, the Name Server is not required.

•Cache (default: selected, which means Yes) For a deselected check box, the HTTP request should not download cached pages. For a selected check box, the HTTP request downloads cached pages if available, otherwise the request is forwarded to the HTTP server.

•Proxy Server (optional) is a string that represents the proxy server information (with a maximum of 255 characters). The default is the null string.

•Name Server (optional, dependent on the URL setting) is the string that specifies the IP address of the name server. The address is in dotted IP address format.

•Operation (default: HTTPGet) If you want HTTPRaw, which represents the HTTP request with user defined payload, instead of the default HTTPGet which represents the HTTP get request, use the drop-down menu and make that choice.

•Raw Request (required if the Operation is HTTPRaw; not available if the Operation is HTTPGet) is a string that is only needed if the Operation is HTTPRaw. It allows you to invoke other types of HTTP operations other than the simple GET operation.

•Request Size (1 - 16384) (required) is a number that represents the number of octets (in bytes) to be placed into the data portion of the packet. The default is 28.

Step 10 From Step 2, if you chose DHCP, you have no information to add. Proceed to Step 11.

Step 11 You return to Figure 7-48 and additional columns of information now appear based on the Protocol information you provided.

•Precedence (default: All) Click the drop-down menu to select the other Precedence TOS choices, 0 to 7. These values represent the three most significant bits of the ToS field in an IP header. The meanings of the Precedence values are specified in Table 7-1, "Meanings of Precedence Values."

Note ISC maps the 0 - 7 PRECEDENCE values to the three most significant ToS bits by left-shifting the value by five positions.

Note Type of Service does not apply to the DNS and DHCP types of SLA probes. ISC ignores any ToS value set for these two types of SLA probes. For example, if you first select a ToS value of 5, then select the DNS, DHCP, and ICMP Echo protocols for an SLA probe, ISC applies the selected ToS value to the ICMP Echo probe only.

•DSCP (default: All) Click the drop-down menu to select the other DSCP TOS choices, 0 to 63. These values represent the six most significant bits of this ToS field in an IP header. The interpretation of these TOS values is user specified.

Note ISC maps the 0 - 63 DSCP values to the six most significant ToS bits by left-shifting the values by two positions.

Note Type of Service does not apply to the DNS and DHCP types of SLA probes. ISC ignores any TOS value set for these two types of SLA probes. For example, if you first select a TOS value of 5, then select the DNS, DHCP, and ICMP Echo protocols for an SLA probe, ISC applies the selected ToS value to the ICMP Echo probe only.

•Probe Type (default: All) Click the drop-down menu to select from the following types of probes: ICMP Echo; UDP Echo; TCP Connect; HTTP; DNS; Jitter; DHCP; FTP.

Note These probe types are explained in detail in the "Protocols" section.
