Configuring Port Mirroring for VPLS Traffic
You can configure port mirroring for VPLS traffic on the M7, M10i, M120, M320, and the MX Series routers. VPLS port mirroring is supported only M7i and M0i routers with the Enhanced Compact Forwarding Engine Board (CFEB-E). In addition, on M320 routers, VPLS port mirroring is supported only on Enhanced III Flexible PIC Concentrators (FPCs).
To configure port mirroring for VPLS include the port-mirroring statement at the [edit forwarding-options] hierarchy level. For more information about configuring port mirroring for VPLS for all platforms supported, see Routing Policies, Firewall Filters, and Traffic Policers User Guide.
