Customer-Edge Device Configuration
This example shows the commands necessary to configure E-LMI on the CE device. Beginning with
Cisco IOS Release 12.2(37)SE, the switch can be configured as the CE device.
This example enables E-LMI globally, but you can also enable it only on a specific interface. However,
if you do not enter the ethernet lmi ce global configuration command, the interface will be in PE mode
by default.
Switch# config t
Switch(config)# ethernet lmi global
Switch(config)# ethernet lmi ce
Switch(config)# exit
Note For E-LMI to work, any VLANs used on the PE device must also be created on the CE device. Create a
VLAN by entering the vlan vlan-id global configuration command on the CE device, where the vlan-ids
match those on the PE device and configure these VLANs as allowed VLANs by entering the switchport
trunk allowed vlan vlan-ids interface configuration command. Allowed VLANs can receive and send
traffic on the interface in tagged format when in trunking mode.
Displaying E-LMI and OAM Manager Information
You can use the privileged EXEC commands in Table 39-4 to display E-LMI or OAM manager
information.
