Using Ethernet Local Management Interface Commands

---

Ethernet Operations, Administration, and Maintenance (E-OAM) consists of three main feature sets:

•IEEE 802.1ag and ITU-T Y.1731 Connectivity Fault Management (CFM).

•IEEE 802.3ah Ethernet OAM discovery, link monitoring, remote fault detection, and remote loopback.

•Ethernet Local Management Interface (Ethernet LMI), which allows a customer edge (CE) network element to obtain user network interface (UNI) and Ethernet virtual circuit (EVC) status and service attribute information from the service provider edge.

Ethernet LMI is a protocol between the CE network element and the provider edge (PE) network element. It runs only on the PE-CE UNI link and notifies the CE of connectivity status and configuration parameters of Ethernet services available on the CE port. Ethernet LMI interoperates with an OAM protocol, such as CFM, that runs within the provider network to collect OAM status. CFM runs at the provider maintenance level. Ethernet LMI relies on the OAM Ethernet Infrastructure (EI) to work with CFM for end-to-end status of EVCs across CFM domains.

The IOS OAM manager streamlines interaction between OAM protocols, and handles the interaction between CFM and Ethernet LMI. Ethernet LMI interaction with the OAM manager is unidirectional, running only from the OAM manager to Ethernet LMI on the U-PE side of the switch. Information is exchanged either as a result of a request from Ethernet LMI or triggered by the OAM manager when it receives notification of a change from the OAM protocol. The following type of information is relayed:

•EVC name and availability status

•Remote UNI name and status

•Remote UNI counts

Ethernet LMI is typically disabled by default.

Supported Network Elements

You can run the Ethernet LMI commands on the following network elements:

•Cisco 7600 Series Routers

•Cisco Catalyst 3750 Metro Series Switches

•Cisco Catalyst 6500 Series (IOS) Switches

•Cisco ME 3400 Series Ethernet Access Switches

•Cisco MWR 2941 Mobile Wireless Routers

See Part 1—Cisco VNEs for details on the software versions Cisco ANA supports for these network elements. To run the Ethernet LMI commands, the software on the network element must support the Ethernet LMI technology.

Configuring Ethernet LMI Components

The following sections explain how to configure Ethernet LMI components:

•Enabling Ethernet LMI Globally

•Configuring Multipoint-to-Multipoint or Point-to-Point Ethernet Virtual Connection

•Configuring UNI on an Interface

•Enabling Ethernet LMI on an Interface

•Configuring the Service Instance VLAN ID on an Interface

Note In the GUI, parameters that are displayed in bold text are mandatory.

---

Enabling Ethernet LMI Globally

Use the Enable E-LMI Global command to globally enable Ethernet LMI on all interfaces.

---

Step 1 In the inventory window, expand the Logical Inventory tree.

Step 2 Right-click the Ethernet LMI node and choose Commands > Enable > Global E-LMI. The Global Ethernet LMI dialog box opens.

The command enables Ethernet LMI on all interfaces and does not require any input parameters.

Step 3 To run the command, click Execute.

Any errors are displayed in the Result tab.

Step 4 To close the dialog box, click Close.

---

Configuring Multipoint-to-Multipoint or Point-to-Point Ethernet Virtual Connection

Use the Configure MultiPoint To MultiPoint or Point To Point EVC command to configure multipoint-to-multipoint or point-to-point Ethernet virtual connection (EVC).

---

Step 1 In the inventory window, expand the Logical Inventory tree.

Step 2 Right-click the Ethernet LMI node and choose Commands > Configure MultiPoint To MultiPoint or Point To Point EVC. The Configure MultiPoint To MultiPoint or Point To Point EVC dialog box opens.

Step 3 By default, the General tab is selected. Enter values for the following parameters.

Input Parameter	Description
Evc Name	Name of the Ethernet virtual connection.
Uni Count No	Unified network interface (UNI) range, from 2 to 1024. The default is 2.
Vlans to apply cross check to ([1-4094])	VLAN ID range from 1 to 4094.
Domain Name	Name of the domain.

Step 4 To see the commands that will be applied on the device, click Preview.

You can view the commands in the Result tab. You can go back and make any required changes to the input parameters.

Step 5 To run the commands, click Execute.

Any errors are displayed in the Result tab.

Step 6 To close the dialog box, click Close.

---

Configuring UNI on an Interface

Use the Configure UNI in an Interface command to configure UNI on an interface.

---

Step 1 In the inventory window, expand the Logical Inventory tree.

Step 2 Right-click the Ethernet LMI node and choose Commands > Configure UNI in an Interface. The Configure UNI in an Interface dialog box opens.

Step 3 By default, the General tab is selected. Enter values for the following parameters.

Input Parameter	Description
Interface Name	Name of the interface.
Uni Id	Unified network interface identifier.

Step 4 To see the commands that will be applied on the device, click Preview.

You can view the commands in the Result tab. You can go back and make any required changes to the input parameters.

Step 5 To run the commands, click Execute.

Any errors are displayed in the Result tab.

Step 6 To close the dialog box, click Close.

---

Enabling Ethernet LMI on an Interface

Use the Enable On Interface command to configure Ethernet LMI on the interface. If Ethernet LMI is disabled globally, you can use this command to enable it on specific interfaces.

---

Step 1 In the inventory window, expand the Logical Inventory tree.

Step 2 Right-click the Ethernet LMI node and choose Commands > Enable On Interface. The Enable On Interface dialog box opens.

Step 3 By default, the General tab is selected. Enter a value for the following parameter.

Input Parameter	Description
Interface Name	Name of the interface.

Step 4 To see the commands that will be applied on the device, click Preview.

You can view the commands in the Result tab. You can go back and make any required changes to the input parameters.

Step 5 To run the commands, click Execute.

Any errors are displayed in the Result tab.

Step 6 To close the dialog box, click Close.

---

Configuring the Service Instance VLAN ID on an Interface

Use the Configure Service Instance Vlan Id on Interface command to configure an Ethernet service instance on the interface.

---

Step 1 In the inventory window, expand the Logical Inventory tree.

Step 2 Right-click the Ethernet LMI node and choose Commands > Configure Service Instance Vlan Id on Interface. The Configure Service Instance Vlan Id on Interface dialog box opens.

Step 3 By default, the General tab is selected. Enter values for the following parameters.

Input Parameter	Description
Interface Name	Name of the interface.
Service Instance Id	Per-interface Ethernet service instance identifier that does not map to a VLAN. The identifier is from 1 to 8000.
