Previously with PIX version 6.3 you could debug packets in realtime. i.e with the debug packet command.
Looking through the ASA 7.2(2) commands the debug packet command no longer exists. Though the packet-tracer command exists this is not in realtime.
Does anyone know how you debug packets with the ver 7.2(2).
Create an ACL identifying the traffic you want to debug. Create a capture specifying the ACL and interface the traffic is entering.
access-list capture permit ip host x.x.x.x y.y.y.y
capture mycapture access-list capture interface inside
show capture mycapture detail dump
