policy-map priority drops

[dm]

Hello!

I run cisco 3845 with 12.4.24T3.

I have following :

policy-map ZAB
class TELNET
    bandwidth percent 10
class MAIL
    bandwidth percent 10
class ICMP
    bandwidth percent 10
class NOTES
    bandwidth percent 10
class WTS
    bandwidth percent 20
class voice
    priority percent 30
class class-default
    fair-queue

policy-map tunnel_zab_gre_oil
class class-default
    shape average 1000000
  service-policy ZAB

and I have this on gre tunnel interface.

Users complains about voip quality and sometimes I see drops in voip class.

And they are marked as b/w exceed drops.

But, as I see, reserved bandwidth is always higher than real bandwidth.

What can it be?

Thank you!

Hi,

can you post output of show class-map voice.

Regards.

Alain.

yes, shure:

p100-cr3845-1#show class-map voice
Class Map match-all voice (id 13)
   Match ip  rtp 16384 16383

btw, channel can be considered as internet- this is leased channel with 1 Mbit declared bandwidth.

Is it possible that router drops packets in priority queue if there are problems with channel?

your policy map is not applied on a tunnel interface?  ---> show policy-map interface

p100-cr3845-1#sh policy-map interface tunnel 7
Tunnel7

  Service-policy output: tunnel_zab_gre_oil

I'm not newbie :-)

btw, how do you think I see b/w drops if police is not applied?

I'm not newbie :-)

I never said that

I wanted to be sure it was a tunnel interface.

Can you post the output you saw when there was drops.

Regards.

Alain.

I'll post output as soon as I'll get drops again.

thank you!
