Port Monitor on 6513

I am troubleshooting a vlan spanning issue on a 6513 switch and am looking for any suggestions. Here are the particulers:

Version 12.2(18)SXD3

monitor session 1 source vlan 69

monitor session 1 destination int g6/35

Show monitor returns:

Type Local Session

Source VLANS

Both 69

Destin Ports Gi6/35

The traffic happens to be routed between vlan 60 and vlan 69, both on the switch. When I capture the traffic, it looks as though I am only receiving half of the conversation(from vlan 69-->vlan60). I don't see the other half of the conversation.

The strange part is, I have a half dozen ports on a connected 3750 switch in vlan 69 that I see all of their traffic. So I am looking to the 6513 for issues/problems.

Anybody have some suggestions?

Re: Port Monitor on 6513

Hmm...its been a while since I worked on this, but are there ports where you are seeing half of the traffic set to half-duplex vs full-duplex for the ones showing all traffic?
