Frame-Relay broadcast queue

francisco_1 · ‎09-30-2010

when it comes to frame-relay traffic shaping, routing packets will not use the per-VC queue if they are broadcasts or multicast and instead they will go to the broadcast queue instead of the per-VC.

What i would like to know is if possible to see the statistics for that hidden broadcast queue?

Ok. The good thing i can answer my own question

The frame-relay broadcast queue is a special interface-level priority queue used to store and send psedo-broadcast packets.

The "frame-relay broadcast-queue" command can be used to rate limit the depth, bit per second or packet per second rate of broadcast sent out the link.

to view the stats,

Serial1/0 is up, line protocol is up

Broadcast queue 0/64, broadcasts sent/dropped 1083/0, interface broadcasts 259

to rate limit the queue

int serial1/0

frame-relay broadcast-queue 16 16000 10
