I have been reading the postings on this site trying to retrieve the MAC address for the client devices (computers, printers) attached to our switches. We have approximately 500 switches and I need to map the mac address to the switch. It appears the OID information is for SNMP v2. We are restricted to using only SNMP v3. I have tried using the Cisco SNMP Object Navigator without any success. Any assistance would be greatly appreciated.
Found it! For anyone else looking for the OID here it is:
SNMPv2-SMI::enterprises.9.9.315.1.2.1.1.10
This lists the MAC address associated with the switch port. I have only test this on a 3750. If you have an IP Phone connected to the same port with a computer, only the computers MAC address is listed.
