get mac address

[amisu]

Hi,

is there a OID that can show me the mac-address of the attached device to the port on cat4506 or 2950 (IOS)?

i think that ciscoworks do it

thanks

"sh ip arp" shows all mac address the switch has, but there is no info on which particular port the host is connected to.

Hi,

Have a look at

Using SNMP to Find a Port Number from a MAC Address on a Catalyst Switch

http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a00801c9199.shtml

and

How To Get Dynamic CAM Entries (CAM Table) for Catalyst Switches Using SNMP

http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a9b.shtml

The CAM table contains what you are looking for, namely MAC address to port information.

This should solve your problem.

Hope this helps
