I just added a Catalyst switch with snmp v.3 configured. The cpu and memory monitors were set ok. But there's no interface at interface tab. I tried to rediscover them, but nothing happens. 

At Actions / Configure Ports menu, i see the interface list. All of them is there. But still nothing at interface tab.

I went to the MIB browser and tried to get the information. It was list with sucess.

Any help? I got 10 more switches to add, but i'll only do that if i can monitor all the interfaces.

Thanks.

Antonio.
