I have this switch:

system.sysDescr.0 = 3Com Baseline Switch 2952-SFP Plus Software Version 5.20 Release 1101P10
Copyright (c) 2004-2010 3Com Corporation. All rights reserved.
system.sysObjectID.0 = OID: enterprises.43.1.8.73
system.sysUpTime.0 = Timeticks: (1535759) 4:1
system.sysContact.0 =
system.sysName.0 = P101 3Com Baseline Switch
system.sysLocation.0 = P101
system.sysServices.0 = 78

with snmpwalk I can query anything except mac address tables. When I query these tables I try by OID (I think is correct) or by name.. but I am not getting anything back. Does this switch support these tables?

Thanks
Jola

Re: Does 3Com Baseline Switch 2952-SFP support dot1qTpFDB/dot1dFdb table

I checked, and the manual for this device is available from their website. You should be able to find out there.

Re: Does 3Com Baseline Switch 2952-SFP support dot1qTpFDB/dot1dFdb table

I have the same issue and finally figure it out.
Do a full snmp walk and grep for the following,
grep "2.17.7.1.2.2.1.2.1"
you will see entry like the following:

SNMPv2-SMI::mib-2.17.7.1.2.2.1.2.1.x.xx.xxx.xxx.xx.xx = INTEGER: 30

The number "30" after "INTEGER" is the port number,
the string after 2.17.7.1.2.2.1.2.1 is the MAC address in decimal format(CISCO format).

Now all needed to be done is to convert that to a format you normally use.

the perl extension NET::MAC is perfect tool for that.

If you have any question, please let me know.

Thank you Frank!

my output is in format:

17.7.1.2.2.1.2.1.112.113.188.31.69.78 = 5

so I actually couldn't grep for "2.17.7.1.2.2.1.2.1" :) but I actually went through whole snmpwalk and figured it!

I used net::mac and it works perfect.

Thanks for your help.
