Problem Description
We are trying to deploy COS in our network..
The network diagram looks like the one below.
There is multiple types of traffic being generated by the media gateway including voice
Voice control and voice signaling configured in different subnets.
To identify this traffic on M10 I ingress fe-0/3/0 interface we have deployed firewall filters and have assigned this traffic different PLP and forwarding classes according to the proposed COS model by the customer.
The COS model can be seen below and the appropriate configuration for Abbottabad M10i router is attached with problem description.
COS Model
Class / Output Ques / Packet Marking / RED Profile / DescriptionQue # / Priority / Rate / Size / PLP / DSCP / EXP
NC / 3 / Medium High / 4% / Rest / Low / CS6 / 6 / Tail drop / Network Control(Routing,RSVP etc)
EF / 1 / High / 70% / 10 ms / Low / EF / 5 / Tail drop / Real time voice/video
AF4 / 4 / High / 20% / 30 ms / Low / AF41 / 4 / Tail drop / Signaling(Sigtran,Urgent O&M)
AF1 / 2 / Medium-low / 4% / 100 ms / Low
high / AF11
AF12 / 1
2 / PLP low
PLP high / O&M,Intranet low drop
Intranet high drop
BE / 0 / Low / Rest / Rest / High / BE / 0 / PLP-high / Best Effort Traffic
The issue is that we can not see any traffic in expedited forwarding class at ingress interface expedited forwarding queue and egress interface lsq-1/2/0 expedited forwarding queue.
The out put for both ingress and egress interface queue counters can be seen below
