Hi Rodney,
Thanks for the response.

The c7200 interface exhibiting the problem (Fa0/0) is configured with
two dot1q subints and is doing traffic interception/redirection with
WCCP (for WAAS). This means it's handling pre-optimised ingress
traffic, GRE encapsulating and forwarding to the WAE back out via the
same interface, then dealing with the post-optimised, GRE-encapsulated
traffic again on ingress.

I know it's far from ideal, but am I likely to see an improvement if I
move away from the dot1q subint and provide connectivity to the WAEs
via a dedicated c7200 interface? The router would still be handling
the same amount of traffic, but it wouldn't all be on the same
interface. I'm not familiar enough with c7200 architecture to know
what impact, if any, this would have.
If that doesn't work, I'm going to have to try and shift WCCP. I think
we're asking these NPE-400s to do a bit too much work.
Fa0/0, in this case, is nailed up at 100-full. It connects to a
10/100/1000 switchport on a WS-X6148-GE-TX line card (c6509-SUP2) but
that's nailed up at 100-full too.
