Configure Autogenerated CFM on C-VLANs

Use this procedure to configure the autogenerated CFM MEP and MIP level for every C-VLAN on the chassis.

To configure autogenerated CFM on SPBM B-VLANs, see Configure Autogenerated CFM on SPBM B-VLANs.

Note

Note

For C-VLANs, you can only use autogenerated CFM MEPs.

Important

Important

CFM supports one MEP or MIP on each C-VLAN. Only autogenerated CFM provides support for configuring MEP and MIPs on C-VLANs. You cannot explicitly configure C-VLANs.

About this task

When you enable this feature, you create a global MD (named cmac) for all the customer MAC (C-MAC) MEPs. This MD has a default maintenance level of 4, which you can change with the level attribute. The autogenerated CFM commands also create an MA for each C-VLAN, a MEP for each C-VLAN, and associate the MEP with the corresponding C-VLAN and a MIP with the C-VLAN.

All the MEPs that the device creates use the MEP ID configured under the global context, which has a default value of 1. The device automatically associates the MEPs with the C-VLANs configured. The MIP level maps to the global level. The device automatically associates the MIP level with the C-VLANs configured when you enable the feature.

The feature is disabled by default.

CFM Global Field Descriptions

Use the data in the following table to configure the global MEP and MIP parameters.

Name

Description

SpbmAdminState

Enables or disables autogenerated CFM for B-VLANs. The default is disable.

SpbmLevel

Specifies the global SPBM CFM maintenance level for the chassis within the range of 0 to 7. The default is 4.

Only configure global CFM at one MD level for each chassis for each VLAN type.

SpbmMepId

Specifies the global MEP ID within the range of 1 to 8191. Select a unique ID for each switch to ensure that the MEPs are unique across the network. The default is 1.

CmacAdminState

Enables or disables autogenerated CFM for C-VLANs. The default is disable.
