Anyone have any connections into an MPLS network that is running VoIP that has to have traffic shaping on their WAN links?

Andy,

I am using putting all my traffic shaping and QoS together and was wondering if you ran into any issues with large WAN links over-running smaller WAN links. My issue is between my OC-3 and my T-1 connected branches. I've got a config worked out I was just wondering if I could scrub it against someones config that was being used in production. I'm interested in just the policy-map and the class-map statements. Do you mind?

We only have a very small 256K connection over the MPLS with 4 voip channels, but here are the bits you asked for.

class-map match-all voip
match access-group 100
class-map match-all eigrp
match access-group 101
class-map match-all bgp
match access-group 102

policy-map voip
class voip
priority 128
set ip precedence 5
class bgp
bandwidth 8
class class-default
set ip precedence 3
policy-map LLQ
class voip
priority 1400
class eigrp
bandwidth 8

map-class frame-relay fr-shaping
no frame-relay adaptive-shaping
frame-relay cir 256000
frame-relay bc 2560
frame-relay mincir 256000
service-policy output voip

If I have missed anything out the let me know.

Andy, thanks for posting that information. Looks like we have similar commands, but my issue is that I have an OC-3 that has to feed about 80 T-1 sites right now. Here is what I have so far (work in progress. I'm just wondering if it will work as I expect it too. (Really need that OC-3 in the lab)

Heh, it is at this point I start to wish I had never aswered your original question and hide under a rock until someone with more letters after their name comes along!

Andy,

Don't worry about it. I just wanted some real comparisons to look at is all. Examples on Cisco's website are not the best to go after. I appreciate your posting. Earned you a star. Thanks again.

Carl
