Distributed CBWFQ with LLQ

[avasko]

I'm trying to implement CBWFQ (w/LLQ) on a 7507 series router. According to Cisco's documentation, I need to run in distributed mode on the VIP instead of the RSP after IOS version 12.1(5)T. I am not familar with the distributed configuration for WFQ on the VIPs. Most examples deals with FR and I have point to point T1s. Does anyone know of any links or have examples implementing distributed CBWFQ (wLLQ) for P2P?

I'm about to implement this myself. Have a look at the following links:

Thanks for the links, but I can't seem to access them. Do these links require partners & resellers accounts?

Here is a config example I did for VoIP on IOS 12.1(20) running on a 7513 with RSP-4 & VIP2-4:

class-map voice-traffic

match access-group 102

class-map voice-signaling

match access-group 103

policy-map voice-policy

class voice-traffic

priority 56

class voice-signaling

bandwidth 8

class class-default

fair-queue

interface Multilink 1

service-policy output voice-policy

access-list 102 permit udp any any range 16384 32767

access-list 103 permit tcp any eq 1720 any

access-list 103 permit tcp any any eq 1720

The commands change slightly in IOS 12.2.

Thanks for the example! It looks similar to mine. Ours did work. We were getting very few hits on our access lists. What type of router did you use?
