Is there a way to use SNMPWALK to get entire MAC addr table instead of per VLAN?

Hi experts,

I have a dilemma here that I need to use snmpwalk and get the entire MAC address table from the switch. I'm aware that I need to use <snmp string>@<VLAN id> as the string to get the MAC address table for that VLAN.

e.g. to get MAC address table of vlan 1101 I do this:

snmpwalk -v2c -c public@1101 172.17.254.1 1.3.6.1.2.1.17.4.3.1.1

However I do need to get the entire MAC address table of all the VLANs on the switch. How do I do it??

thanks!!

You cannot do it.  You need to use community string indexing to pull the MAC address table from each VLAN.  Even using SNMPv3, you cannot get all of the VLANs' MAC address tables with one request.

That's what I figured... Thanks for confirming it...
