cfm vlan-table

Use this command to configure a logical grouping of multiple service IDs to a primary service.

Syntax

Parameters

Defaults

If enable or disable are not specified, the specified VLAN table configuration is configured but not active (the configured selector list is not associated with the primary selector).

When using the “no” option, if no option is specified, all configured VLAN tables are deleted. If a primary selector is specified, the VLAN table for that primary selector is deleted. If both the primary selector and the selector list are specified, the selector list for that primary selector is deleted.

Mode

Global configuration command.

Usage

The current CFM implementation only supports VLAN services. When configuring a CFM service, the configured ID for the service is checked against configured VLAN tables. The primary selector defines the ID of the service being modified. If a VLAN table with a primary selector exists matching the CFM service ID being configured, the VLAN table selector list is applied to that service ID. For example: if the configured service is VLAN 10 and a VLAN table configuration for primary selector 10 is configured and enabled, the selector list associated with primary selector 10 is applied to the CFM service.

One or more service IDs may be provided in the selector list. IDs specified in the selector list are associated with the primary service. Specifying the enable command option activates the association between the IDs in the selector list and the CFM service. Specifying the disable command option disables the association of the IDs in the selector list with the CFM service. The VLAN table remains configured, but is not active.

Maintenance points (MIP or MEP) associated with a CFM service will be able to receive CFM PDUs on any of the active IDs defined in the VLAN table selector list. MEPs may be configured with a Primary VID, which must be included within the list of selectors defined by the enabled VLAN table, otherwise there is a one-to-one relationship between the VID and the service. With a primary VID defined, the MEP can transmit tagged PDUs using that primary service. If no primary VID is defined by the maintenance point, the primary selector of the service, as defined in the MA configuration, will be used by the maintenance point to tag its transmitted PDUs.

The “no” form of this command removes all VLAN tables, a specific primary selector VLAN table or the selector list for a specified primary selector as specified in the Defaults section above. A lack of entries in the VLAN table provides a one to one relationship between a service ID and the service.
