Device sensed but inventory collection failed - 3550 switches

Hi,


we have a LMS 3.1 installed in a Windows server and some 3550 switches. All these switches, when doing inventory collection, say that "device sensed, but inventory collection failed".


They have IOS 12.1(14)EA1a and I have seen in this forum that this is the minimum version that is not affected by a bug.


I attached a part of the IC_Server.log.


How can we solve this problem?

LMS 3.1 started to use the ENTITY-MIB to build a more comprehensive inventory for these switches. Unfortunately, due to a device bug, 3550s must be running 12.1(19)EA1 or higher to get a working ENTITY-MIB. A similar bug exists for 2950s, but they can run 12.1(11)EA1 or higher.

I have seen in the LMS 3.1 supported devices table that these devices need IOS version greater or equal than 12.1(19)EA1c.


We had a LMS 2.6 and these devices were supported with a IOS 11.2(8).


Why is not possible to manage them with an IOS version older than 12.1(19)EA1a?
