Hi,
I have a cisco 6832 in production and there is a need for me to capture on the downlink, which is a trunk port. Now, packets capture works like a charm on routed port but when I try on VLAN of for that matter on the interface, it captures nothing. In fact, it complains that no capture session is in place.
monitor capture buffer BUF size 2048 max-size 1518 circular
1.
ip access-list extended FILTER
permit ip any any
permit ip any any
monitor capture buffer BUF filter access-list FILTER
2.
monitor capture point ip cef POINT vlan 1111 both

Attach the buffer to the capture point:
monitor capture point associate POINT BUF
4.
Start the capture:
monitor capture point start POINT
