CBWFQ conversation limit

[ramonalvarez]

Hi,

I just configured qos in our network, but i have to increase limit of available conversations for priority traffic, i am using priority for our voip traffic, how can i do that without disable CBWFQ? take a look of the output:

Conversations 240/257/256 (active/max active/max total)

Hello,

could you give a little more information on what you configured and where you got this output?

LLQ will only use one queue per class and only 256 classes are supported per policy-map.

So what do you mean with "increase limit of available conversations for priority traffic"

because with CBWFQ and LLQ there is no per-flow concept, but only a class based approach to QoS.

I configured a service policy with their class-map to give priority of the traffic but in some cases when the link is overloaded i see packet drops for my pririty traffic, and i see on the interface that is a limit of conversations is :

Conversations 2/258/256 (active/max active/max total)

Class-map: FID (match-all)

7154995 packets, 3728431477 bytes

5 minute offered rate 915000 bps, drop rate 0 bps

Match: access-group name PRIORITY_FID

Queueing

Strict Priority

Output Queue: Conversation 264

Bandwidth 1152 (kbps) Burst 8000 (Bytes)

(pkts matched/bytes matched) 210/131074

(total drops/bytes drops) 0/0

thanks,
