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.
