Priority Queue Question

I've added the following config to the ASA at one of my remote sites:

class-map Voice

match dscp ef

match tunnel-group X.X.X.X

policy-map Voice-Priority

class Voice


policy-map Traffic-Shaping

class class-default

  shape average 800000

  service-policy Voice-Priority

priority-queue outside

service-policy Traffic-Shaping interface outside

But it doesn't seem like anything is getting into the priority queue:

Interface outside:

  Service-policy: Traffic-Shaping

    Class-map: class-default

      shape (average) cir 800000, bc 3200

      (pkts output/bytes output) 388107/257765342

      (total drops/no-buffer drops) 2847/0

      Service-policy: Voice-Priority

        Class-map: Voice



          queue limit 64 packets

          (queue depth/total drops/no-buffer drops) 0/0/0

          (pkts output/bytes output) 0/0

        Class-map: class-default

          Default Queueing

          queue limit 64 packets

          (queue depth/total drops/no-buffer drops) 54/2847/0

          (pkts output/bytes output) 388238/257909374

It's only been a few hours or so and not too many calls are made from that site, but I wanted to be sure I was on the right track.  My fear is that the web filter device that is inline withe the ASA is stripping the tag off my voice packets.

Everyone's tags (4)

Priority Queue Question

Hi Bro

Maybe the incoming voice packets into your FW isn't marked with ef. For this reason, you don't see anything at all. I hope the QOS isn't tied to a subinterface, as QOS is only supported on the main interface itself. What you're doing here is QoS Configuration based on DSCP. You could refer to this URL for troubleshooting purposes.

Did you marked on the Cisco Catalyst switchports, which ports are ef?
