Monitoring tunnel interface traffic

[david.williams]

We've integrated WLSM with IDSM-2 and want to monitor wireless traffic terminating on tunnel interfaces. Can't find a way to configure SPAN or VACL on IOS 6500 to capture traffic. Any suggestions?

Doesn't help on tunnel interfaces; the traffic is encapsulated and you can't get to it until it routes out the interface. So monitoring the VLAN is out.

And the gateway for the tunnel interfaces is on another device.
