Hi Group,
I am hoping someone might be able to shed some light on the above subject. You use the aggregate policing or microflow policing methods on a 6500. Can you use the aggregate policing method at the same time with PFC/DFC QoS commands like the commands below
Interface Gigabit2/8
wrr-queue bandwidth percent 5 55 40 0 0 0 0
priority-queue queue-limit 30
wrr-queue queue-limit 5 25 40 0 0 0 0
wrr-queue threshold 1 100 100 100 100 100 100 100 100
wrr-queue threshold 2 80 100 100 100 100 100 100 100
wrr-queue threshold 3 90 100 100 100 100 100 100 100
wrr-queue cos-map 1 1 4
wrr-queue cos-map 2 1 0 1
wrr-queue cos-map 3 1 2 3 6 7
so after the last command, I will add
'service-policy output voip_policy' to police voice traffic to a certain bandwidth.
This are the commands used to match the voice traffic
mls qos
mls qos aggregate-policer voip_1mbps 1000000 2000 conform-action
transmit exceed-action drop
class-map match-any voice_qos
match ip dscp ef
policy-map voip_policy
class voice_qos
police aggregate voip_1mbps
The idea is to use the aggregate policer command to police voice traffic to a certain bandwidth on egress interface since voice is in the priority queue and priority queue will always get sent first.
Any comments will be greatly appreciated. Thanks
Deji
