My guess is that this would work, though I don't really know the ASR
platform or what PW-SPAN actually is. I'm assuming the PW-SPAN
destination interface is a plain physical interface on the 7600 side.

We've previously used something similar with ERSPAN instead of PW-SPAN.

You could also use an ERSPAN session on the 7600 toward the wireshark
machine if you have IP reachability between them.
