HP/3Com switches only show VLAN interface

I'm not sure whats going on: only my HP/3Com switches do this on Switch Port Mapper - it just discovers 2 ports. One is the bridge aggregation, and the other is a VLAN interface which gives me all MACs that have passed through this switch. I want it to give me all the ports and MACs going through them.

All other switches work great for this app.

It's hard to tell outright. It's probably either that the switches do not expose this information via SNMP, or they do so in a format that the app didn't understand.

We may be able to see what's happening there with a tool called snmpwalk, which dumps the entire SNMP tree. If you could run the snmpwalk tool against your switch and send us the output via a support ticket, we may be able to tell why this is happening and whether it can be fixed. Please also attach a XML file generated by the Port Mapper app against this switch.

Snmpwalk can be downloaded here.

Thanks for getting back. I created a support ticket, with snmpwalk results provided.
