Re: [NV-L] Switch Analyzer and 3Com4228G

As I understand it, multiple vlans are
implemented  in SNMP by Cisco equipment by means if community-string
indexing. ITSA supports this. If that device implements multiple vlans
the same way, then it should work. If it does it in some other proprietary
way, then you will only see stuff for the default vlan. 

Cordially,

Are you sure you have the correct community string
in snmpconf?
Can you get it to respond to an snmpwalk of the bridge MIB?  If this
fails
      snmpwalk <IP address of switch> dot1dBridge
but this works
      snmpwalk -c <community>  <IP address
of switch> dot1dBridge
then you need to update your SNMP options.


You could also try loading \usr\ov\snmp_mibs\rfc1493-bridge.mib  (loadmib)
and then querying the device using the MIB browser (browser) for things
under .iso.org.dod.internet.mgmt.mib-2.dot1dBridge (.1.3.6.1.2.1.17)

Hello ALL!
I have a small question about Tivoli Switch Analyzer 1.3:
We are using Tivoli Switch Analyzer 1.3 and Windows 7.1.4 on Windows 2003
server.
We can’t discover VLAN information from 3Com4228G switches, but have
successful VLAN discovery from Cisco switches.
Can Tivoli Switch Analyzer 1.3 discover VLAN info from 3Com4228G?

Thank you.
Dmitry Baturin
