Drops in LLQ with compress header ip rtp

[patcbr600]

Hello,

I have a cisco 7200 with 12.3(12) with LLQ configured and compress header ip rtp in the class,(ppp link)

policy-map QPM_GC2WAN

description gestao congstao nos int WAN core com CRTP

class QPM_FGCVoice

priority 370

compress header ip rtp

class QPM_FGCBusi2

bandwidth percent 50

queue-limit 128

class class-default

fair-queue

From the show policy-map I see that the router discard all the packets for the class QPM_GC2WAN

and increments erros on the rtp statistis, causing bad quality in the voice traffic, if I remove de compress header ip rtp

from the policy the problem disapear.

WFQ: dropping a packet from the priority queue 39

Thua any one know if is some problem in the configs or some bus in the IOS

IOS: c7200-js-mz.123-12.bin

Did you configure header compression on both ends of the network? You need it on both routers!

Hello,

I have configured on both sides, the same policy-map on the two routers and the output is:

(total drops/bytes drops) 1893/112310

with an 30 second offered rate 60000 bps when the limit is 370k.

Thanks
