Leslie,
have a
few queries re ITSL2 and cisco and nortel devices.
I
believe that ITSL2 requires your kit to support RFC1493, and "maps" the L2
connections with the MAC Fwding table of the device.
Our
devices have the 'default' configuration of 5mins as the timeout for the Mac Fwd
table for cisco and nortel kit. We are seeing the L2 connections appearing and
disappearing continually on the network as the table ages
out.
Is this
normal behaviour and and how can we overcome it?
One
suggestion has been to open out the Mac Fwding table timeout to somewhere
between 15 mins and 3 hrs. Our network people are uneasy about reconfiguring the
timeout of every device on our network to see if this works.
Any
ideas/suggestions?

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.

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

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
