QoS on ISR 1941

Hello all,

I have a problem with the behaviour of the QoS configuration on 1941 router, below is the configuration:

class-map match-all critical_trafic

match access-group 101

policy-map traffic-outbound

class critical_trafic

  set dscp af31

    bandwidth 2000

access-list 101 permit ip host 192.168.11.161 host 192.168.21.156

I have 10Mbps bandwith between the two sites where the two servers reside, and as you can see, I have dedicated 2Mbps bandwith between the two servers. the monitoring of this Qos display:

""Class-map:critical_trafic (match-all)

      373522514 packets, 11549418 bytes

      5 minute offered rate 1000 bps, drop rate 0 bps

      Match: access-group 101

      Queueing

      queue limit 64 packets

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

      (pkts output/bytes output) 84895713/43844002502

      QoS Set

        dscp af31

          Packets marked 1694101

      bandwidth 2000 kbps ""

as you can see, the bandwith offered is 1000bps and this is what the router display all the time meanwhile we have big data to transfer between the two servers.

Please can anybody tell me If I am missing something?

Thank You

QoS on ISR 1941

Hi,

The bandwidth guarantee will only come into play when the link is congested and it is the minimum bandwidth this traffic can use.

I don't see any sign of congestion so it seems this traffic is only consuming 1000 kbs.

Can you provide the entire running config.

Regards

Alain
