SNMP-OID for the MAC of the connected Device
Hello Community,
i am working on a script, which is collecting data from the switches via SNMP.
My problem is, that i need to know the OID which can be used to find the MAC of a Client directly connected to a port of the switch.
May someone had the same problem and can help me :-)
Kind regards,
Robin
I've found the solution:
if the request returns iso.3.6.1.2.1.17.7.1.2.2.1.2.1.0.34.100.189.60.156 = INTEGER: 7, the integer-value represents the port of the MAC-address and the last 6 numbers of the OID represent the MAC-address in decimal format, in this example it means that the MAC-address connected to port 7 is 00:22:64:BD:3C:9C.
Thank you for your help :-)

Hi robinchristes,
Welcome to the community! :)
I suggest you to use the NMS300 ProSAFE Network Management System to monitor the GS724Tv3 switch/es via SNMP. You can download the latest version of NMS300 here.
Also, kindly download the GS724Tv3 MIB file on this link as it might help you with the OID. The link will expire within 2-3 days.
Check the article below as well:
Let us know how it goes.

Hi DaneA,
I have to say, that I am not able to find the mac-address of the clients with the given documents. I have scanned all OIDs of the switch with snmpwalk, and i got some of the macs of connected clients, but not all (which are shown under the section switching-->address-table) although they are online.
For example, the client connected to port 7 is showed as iso.0.8802.1.1.2.1.4.1.1.5.18524162.7.7 = Hex-STRING: 00 22 64 BD XX XX, but the client connected to port 11 doesn't appear.
Is there probably another way to get the other addresses on an indirect way?
Regards,
Robin
I inquired your concern to the higher tier of NETGEAR Support. As per the higher tier of NETGEAR Support, kindly use this SNMP’s OID: 1.3.6.1.2.1.17.7.1.2. E.g: “snmpwalk -v 2c -c public 10.130.181.156 1.3.6.1.2.1.17.7.1.2”.

Since the MAC Addresses is present on the web-GUI of the GS724Tv3 switch, what are these devices? Are these devices connected directly to the GS724Tv3 switch? What is the specific type of device wherein you are not able to locate via OID?

the devices (mostly computers) are directly connected to the switch, for example in the image you can see the MAC of a Elitegroup Mainboard on g9
