Strange User Tracker Problem LMS 2.6

Unanswered Question
May 20th, 2008

Hi,

Our Ciscoworks server has the following patch levels

Common Services 3.0.6

CM 4.0.10

DFM 2.0.10

RME 4.0.6

CV 6.1.5

User tracker has been working quite well for us on the patch levels described above. However we recently completed a distribution gateway move. That is, we moved the layer 3 SVIs for an entire switch block from one switch to a pair of 6513's / Sup720 with HSRP.

The change simply consisted of shutting down the SVIs on the current switch and then enabling the SVIs on the pair of 6513's (same IP addressing).

Since this change user tracker is no longer able to "fill in" the ip address field for a user located on one of these Vlans.

I have cleared the user tracker database, but still the problem remains. All username and mac address information is being discovered correctly, but the ip address / dns name is blank.

Can anyone help ?

I have this problem too.

You must first make sure these new switches have been properly data collected, and show up on the Campus Manager map with the correct green switch icon. Then, you need to make sure the ARP caches on these switches are properly populated with all of the end host MAC/IP entries. Next, check that there is no SNMP view applied on these switches that blocks Campus from polling the ipNetToMedia table.

After that, running a new UT major acquisition should populate the IP addresses. If not, you will need to enable vmpsadmin debugging under Campus Manager > Admin > Campus Data Collection > Debugging Options, run a new UT acquisition, and check the ut.log for one MAC address which is missing its IP info.
