Cisco Nexus 9K - Show MAC addresses from connected stuff

General
1

Hi guys.
Is there a way to show the MAC address of the stuff connected to a switch? i can only see the MAC address of the switch interface per se.

I know this was discussed on 2014. Any update since?
I’ve found this: Checkmk Exchange

But, i installed it… and i cannot yet see what im looking for.

Thank you!!!

This is not so easy. For instance on your Cisco you must first collect all defined VLAN id’s and then you use these id’s as context in your SNMP request.

I have build a MAC inventory for some of our devices.
If you want, you can try this mkp. It is possible that you need to modify the code for your needs. You can say for every manufacturer you need a different approach.
This mkp was build with 1.6 i think. It will not work with 2.0
