Hi Tim,

Unfortunately, not necessarily. The 3550 will only show process switched packets (mostly),
which are either locally generated packets or packets arriving into the receive adjacency
queue for processing by the CPU (in other words, locally destined packets).

Transit packets are ASIC-forwarded (CEF), and 3550 has the tradition of not keeping checks
and balances of what it moves at layer3 level, when things are hardware forwarded.

HTH,
