PCM+ V. 3.2 discovers Switch - Switch links sometimes

[Stuggi]

I have a problem with PCM+ only discovering switch-to-switch links sometimes, at the head office for example it has only discovered one link between a 4204vl and a 2910al, when the network consists of two 4204vls interconnected with 2 trunked gigabit ethernet links, and two 2910als which are each respectivly connected to one of the 4204vls. At another site it there are four 2810s and two 2520 which are all connected to each other through fiber optics, and there PCM+ only detects some of the fibre links.

The first network is over a year old and I've been having this problem since I installed PCM+ on a server directly connected to that network. The other network is connected to the head office network through a WAN, so all the devices are on a separate subnet but directly reachable. I haven't had any problems discovering the actual devices. I had the same problem in both PCM+ 3 and 3.2

Okay, small update, I upgraded the coreswitches in my network to 5406zl-switches, and now everything works as it should, and after a month PCM has also discovered the links between the 2810-24G and 2520-PoE-8G switches at the other site. It's probably something wrong with the old firmware that's running in the 4204vl-switches, I'll try updating it before I deploy them at the new site.
