LMS 3.2 and user tracking problem

[cmarva]

rme 4.3.1

cm5.2.1

cv 6.1.9

dfm 3.2.0

ipm 4.2.0

portal 1.2.0

cs 3.3.0

cwasst 1.2.0

running on windows server 2008.

This was a clean bulid, and we imported all pertinent data from our old lms 2.6 server. This was in september 2010. Everything worked as expected and continues to work except for......

We are in an upgrade cycle for our 4500s. We are upgrading from 12.2.50-sg4 to 12.2.50-sg8, and also upgrading rommon to 12.2.31r-sga4.

It appears that user tracking is not working anymore for the upgraded 4500s. UT still runs, and works perfectly for all other devices, including the 4500s that have not been upgraded yet. I know this sounds goofy, but it really does seem to be the common denominator. I've checked the windows updates, package updates, etc in trying to figure out what made this happen. It really does all come back to upgrading to the above version. All aspects of this server are running great and as expected, it's just that UT for the upgraded 4500s isn't working anymore. I do run the logbackup script weekly (past experience has taught me to do this), and try and keep up with any patches or package updates, etc.

If anyone has seen something similar or can suggest anything, I'd appreciate it. I think I am going to have to open a case on this. Thanks - chris

So the IOS version  from 12.2.50-sg4 to 12.2.50-sg8 is the only change?  No other changes?

Then I would expect it to be an IOS bug with the reading of the mac address table or obtaining the VLAN info.

You  should try to do an SNMP walk of the mac address table for each VLAN

Best open a TAC case for this as you probably need a new IOS image

Michel,

Indeed, it looks like that is the problem. I guess I was focused in on CW rather than the whole picture. But yes, indeed, if I walk the mac table for a vlan on a 4500 that has not been upgraded it works. If I do the same on an upgraded one, I get nothing.

The cautious optimism is that we do have a sup6 at our DR location that is running 12.2.53-sg1 and this test works on that switch. So as long as that

version isn't deferred, we'll test that on one of the older sups to verify.

So thanks for the help, I appreciate it - chris
