SNMP to get number of devices connected to a switch port

[julianelizondo]

I have a Catalyst 2955... is there an OID that could give me the number of devices connected to a switch port???

Exist one link from Cisco to get info OID. I start to use one software much better.

MG-SOFT MIB Browser Professional Edition.

With this one are you available to browse all OID numbers.

Another excellent software from Cisco.

Cisco Network Assistant.

A few choices.

From a raw SNMP perspective you could grab MAC addresses from the switch's CAM tables via SNMP. Method would be similar to the online docs here:

An easier method, if you have CiscoWorks LMS, is to use the Campus Manager/User Tracking tool
