We have a DPT ring with 10 10720 routers on it. The ring is connected to an OC-48 SRP interface on each router.
Voice traffic enters and leaves the 10720 on a Fast Ethernet interface; incoming voice has DSCP46 marking on it, and a strict-priority queue is set up outbound on the Fast Ethernet interface.
Is it possible to apply some form of priority queueing on the SRP1/1 interface on the 10720? I have been trying to find something definite about this but so far I have failed.
Router# conf t
Router(config)# interface srp 2/0
Router(config-if)# srp priority-map transmit 5
Please check this configuration guide, this should help you do the priority or other tasks with the SRP interface.
