Hi
I am trying to get the switch information of an IBM Bladecenter. The switch modules are Nortel Networks Layer 2-3 GBE Switch Module(Copper). OID is 1.3.6.1.4.1.1872.1.18.1
Is there any way to make the data acquisition of this type of switch? In the "IP Device Info" i saw 0 ports an the cricket have no data.
There is some workaround for this type of switch?
Best Regards

We've never tested with this switch, so I couldn't say off the top of my head.
Which version of NAV are you running? Are other switches being detected correctly by NAV? Are there any error messages related to this switch in ipdevpoll.log?
Hi Mortan
Im running version 3.8.6
In the ipdevpoll.log i only have this error:
[ERROR jobs.jobhandler] [inventory se03bc05sw02.priv.fccn.pt] Job 'inventory' for se03bc05sw02.priv.fccn.pt aborted: SNMP request timed out
But the switch respond to snmp querys perfectly from the console:
snmpwalk -v2c -c community SWITCH SNMPv2-MIB::sysDescr.0 = STRING: BNT Layer 2/3 Copper Gigabit Ethernet Switch Module for IBM BladeCenter SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.1872.1.18.1 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (145678900) 16 days, 20:39:49.00

There a are a few known issues with SNMP timeouts when using ipdevpoll:
1. Your device may be slow at generating responses for GetBulk requests. This has at least been demonstrated to be problem with some devices from other vendors.
2. You may want to patch your TwistedSNMP library as described in NAV's NOTES file. We submitted a patch to TwistedSNMP to fix a problem with the timeout not increasing as it should between retries, but we've never received a response. The patch can be found in NAV's contrib directory.
If you've applied the patch and are still getting timeouts, you can set up some more logging in ipdevpoll so we can at least see which plugin times out. Create a file in NAV's config directory called `logging.conf`, and add the following three lines:
[levels] nav.ipdevpoll = INFO nav.ipdevpoll.jobs.jobhandler = DEBUG
Hi Mortan
I have made the patch to TwistedSNMP library but i still receiving the timeout.
Increasing the verbosity of the logs i receive:

Apparently the oidprofiler not recognize the router OID.

No, the oidprofiler's job is to test a device for compatibility with various statistics-related SNMP OIDs that Cricket will use. It rejected the router on this run because its OID profile was already up-to-date.
I'm more interested in the log messages from the 'inventory' job for your router, which was the job that was timing out in your original log excerpt.
Hi Morton, pleased see you again.
Here is my inventory log for this switch. Thanks for your help.

Hi Duarte,
There's the line I was looking for. The Bridge plugin is to blame. I think I've seen this happen before, and although I have my suspicions about what's wrong, I'm not entirely sure.
If you would also add debug logging to that plugin, that would be very helpful. Add the following line to logging.conf:
nav.ipdevpoll.plugins.bridge = DEBUG
