Mirroring can be refined with a MAC filter policy so that only specific MAC addresses, (source or destination), are mirrored. MAC filter policies are defined in the config>filter>mac-filter context. See the 7705 SAR Router Configuration Guide, ‟Filter Command Reference” for configuration information.
A MAC filter can be applied to the ingress or egress traffic on a VPLS SAP based on the source or destination MAC address. The filter can then be used as the source of mirrored traffic using the debug>mirror-source>mac-filter command. Service packets from matching MAC addresses can be mirrored to a local SAP or a remote router.
Mirrored traffic only includes packets as they would appear on the wire. For example, discarded packets in egress queues during congestion are not mirrored.
