UT not discovering MAC on trunk port with IP-phone

Unanswered Question
May 29th, 2009


I have a Lan with interfaces configured for non-cisco-ip-phone. (i.e.: Trunk port with a native data vlan.)

It is impossible de discover Mac on those ports. Note that if I telnet the switch and do a 'sh mac add-table" I see those.

I configured the LMS User-Tracking admin with:

"config trunk for end host disc. = enable on all trunk."

Do I forgot something ?

Edit ut.properties, and set UTGetVlansWithUserPorts=0. Then run a new UT acquisition, and your phones should show up.

I tried to do this allreaddy.

And I did not see any change.

Here is my ut.properties.

Note that I have LMS3.1

Try running a full Campus Data Collection first, then run the UT acquisition.

hi Jim,

I am sorry to call you back , but I need to do this working.

Do I need to do other thing than edit UT.properties ?

Do I need to restart LMS ?

Do I need to schedule a new inventory pooling ?

All you should have to do is run a new Campus Manager Data Collection. This will update the XML files which contain port data required by User Tracking. After the Data Collection runs, start a new UT acquisition. Your end hosts should show up.
