Checking on QoS

[billmatthews]

We have a router that does bandwidth limiting outbound:

....

class TAG-AF22

  set dscp af22

  bandwidth remaining percent 15

...

And inbound policing...

...

class QOS-TEST

  set dscp a11

  police cir 768000

   conform-action transmit

   exceed-action drop

...

Is there a way to show if these thresholds are ever being hit?  For example of QOS-TEST or TAG-AF22 were ever throttled?

Thanks

Bill

Thanks, +5, that's what I was looking for.  From the output I can see the CIR restrictions...

      police:

          cir 768000 bps, bc 24000 bytes

        conformed 43034439 packets, 21546043234 bytes; actions:

          transmit

        exceeded 1303684 packets, 1848827178 bytes; actions:

          drop

But for congestion on the class TAG-AF22 where would I look?  Is it the total drops?

    Class-map: TAG-AF22 (match-any)

      56393724 packets, 39300308195 bytes

      5 minute offered rate 0 bps, drop rate 0 bps

      Queueing

      queue limit 64 packets

      (queue depth/total drops/no-buffer drops) 0/163818/0

      (pkts output/bytes output) 56229899/39112431711

      QoS Set

        dscp af22

          Packets marked 56393724

      bandwidth remaining 15% (264 kbps)

Thanks,

Bill

Depends on how you define congestion.  Total drops records the number of times the queue overflowed; a result of congestion.

Queue depth shows packets currently queued, and when count is more than zero, you have congestion.

Thank you both!
