[c-nsp] QoS help on Cisco 1841 from Covad

[Darryl Dunkin]

What host is xxx.xxx.xxx.xxx? Is that your VOIP gateway?

You are matching both protocol and the destination IP address
(match-all). If this is not the destination of your packets, they won't
match and go to the class-default.

Hello folks,

I'm having some trouble getting my QoS policies for VoIP to work on a
Covad
supplied T1 router. It looks like it's a Frame Relay interface. I have
applied the rules as I normally do on our Point-to-Point circuits, but I
don't see the rules catching any traffic. Can someone loan me another
set of
eyes to see what I'm doing wrong here?

I didn't do the config for the Frame Interface. That's from Covad so I
can't
really mess with that much. I'm only allowed to implement the QoS
policies.

Thanks very much:
