enable vman cep egress filtering ports

enable vman cep egress filtering ports {port_list | all}


Enables the egress filtering of frames based on their CVIDs on ports configured as CEPs.

Syntax Description

port_list Specifies a list of ports.
all Specifies all switch ports.


Egress CVID filtering is disabled.

Usage Guidelines

For a given VMAN and a port configured as a CEP for that VMAN, only frames with CVIDs that have been mapped from the CEP to the VMAN are forwarded from the VMAN and out the CEP.

To view the configuration setting for the egress CVID filtering feature, use the show ports information command.



CVID egress filtering is available only on switches that support this feature, and when this feature is enabled, it reduces the maximum number of CVIDs supported on a port. The control of CVID egress filtering applies to fast-path forwarding. When frames are forwarded through software, CVID egress filtering is always enabled.


The following command enables egress CVID filtering on port 1:

enable vman cep egress filtering port 1


This command was first available in ExtremeXOS 12.6.
