Configure Autogenerated CFM on SPBM B-VLANs

Use this procedure to configure the autogenerated CFM MEP and MIP level for every SPBM B-VLAN on the chassis. This configuration eliminates the need to explicitly configure an MD, MA, and MEP ID and to associate the MEP and MIP level to the SPBM B-VLAN.

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

About this task

When you enable this feature, the device creates a global MD (named spbm) for all the SPBM Nodal MEPs. This MD has a default maintenance level of 4, which you can change with the level attribute. All the MEPs that the device creates use the MEP ID configured under the global context, which has a default value of 1. The nodal MEPs are automatically associated with the SPBM B-VLANs configured. The MIP level maps to the global level. When you enable the feature, the device automatically associates the MIP level with the SPBM B-VLANs configured. The feature is disabled by default.

Important

Important

CFM supports one MEP or MIP for each SPBM B-VLAN only. This means that if you want to use these autogenerated MEPs, you cannot use your existing CFM configuration. You must first remove the existing MEP or MIP on the SPBM B-VLAN. If you want to continue configuring MEPs manually, skip this procedure.

Procedure

  1. In the navigation pane, expand Configuration > Edit > Diagnostics.
  2. Click CFM.
  3. Click the Global tab.
  4. Select enable next to SpbmAdminState.
  5. Click Apply.
  6. To verify the values assigned to MA, MD, and MEP, perform the following steps:
    1. Click the MD tab.
    2. Select SPBM, and then check the MA and MEP values.

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.

This field does not apply for all hardware platforms.

CmacLevel

Specifies the global C-MAC 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.

This field does not apply for all hardware platforms.

CmacMepId

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.

This field does not apply for all hardware platforms.

Bmac
