SNMP Queries - MIB(s) to get IP address of connected devices
11/4/09 6:59 PM
The following questions is related to SNMP queries on a Cisco 2950 ethernet switch.
 
What MIB or combination of MIBs can we use to get IP addresses of all  devices connected to a particular data switch, and what Software version supports this MIB, MIBs.
 
Also, if we know MAC addresses of all devices connected to a data switch, is it possible to get their IP addresses.

Hi Debra,
 
I'm sorry, the CUAE developer forum is probably not the best place for your question.
Please contact the Cisco 2950 switch support team for help in resolving your issue.
 
Thanks,
Neha

thanks for getting back to me.  Is there a forum for the 2950 data switch team or do I need to open a ticket?

I'd suggest subscribing to the Cisco-NSP mailing list: http://puck.nether.net/mailman/listinfo/cisco-nsp] - you'll find all the answers you need. I'd recommend searching the archives first.
 
OT response: Bear in mind that because the 2950 is a L2 switch you'll find it quite difficult to get the IP addresses of connected devices unless they have recently pinged (or been pinged or otherwise connected in some way) by/to the switch - in which case they'll be in the ARP table. Unlikely, but possible. You may want to consider another solution or explain (on the NSP list) what it is you're trying to achieve.
 
We now return you to your regularly schedule program. ;-)
