Campus Manager, User Tracking and a WS-C5500

We have a 5500 switch which is not displaying all the cards in User Tracking. There are a total of 10 cards (including Sup Eng in slot 1). User tracking only shows cards with devices for slots 2-6. That leave 7-10 unaccounted for. Topology Services shows 10 cards under device attributes for the switch.

Any ideas?

TIA for any help.

Re: Campus Manager, User Tracking and a WS-C5500

It appears that we are hitting a bug with the CAT IOS software for the 5500s.

...From the TAC:

"Yes, you are hitting bug ID CSCdx46174 : dot1dBase info does not exist for

ports in any vlan other than vlan1. This is related to CSCdx66883 : SNMP

community string indexing fails on dot1dTptable queries. Mibwalk with

community string in format @ returns incorrect

value. This breaks the UserTracking application. Since the MAC address

cannot be retrieved then UT tables are blank for end hosts. The problem

exists in CatOS software releases 6.3(5), 6.3(6) and 6.3(7). This bug is

also known to affect 5.5(7)-5.5(10) code.

This problem is due to the new way CatOS handles community string

indexing. They no longer respond to queries to VLANs that are not present

on the switch. VmpsAdmin uses ro_community@0 when first polling the switch

for its forwarding table. On previous code, this GETBULK succeeded with a

return of the

IF-MIB. In 6.1(3), the switch will not send anything back. This causes

VmpsAdmin to balk when trying to retrieve all end stations.

The fix has been applied to CatOS software release 5.5(15), 6.3(8),

7.3(1), 7.4(1) and later releases.

So change the code on the switches, reinitialize the UT tables as shown

below, then do a new UT discovery.

# net stop crmdmgtd

# perl C:\PROGRA~1\CSCOpx\bin\ -ut

# net start crmdmgtd "
