Catalyst 3900 4.1.(3) connectivity loss

[agiacometti]

I have a couple of this switches with this strange problem. Two servers, in port 14 and 15 (same ASIC).

I cant ping between them. But if i do a "arp -a" on the server "A", i get the mac from the server "B" (but still cannot ping), and if i do an "arp -a" on the server "B" i dont get the mac from the server "A".

Sometimes, if i reset the port address tables, it fix the problem.... but sometimes it doesnt.

If possible, try to move the servers to different ports and check. Also, see if there are any issues associated with the software version that you are using.

It works (sometimes with some ports) if i move the servers between different ports or switches. But i have several servers with the same problem. Yes, it is a workaround, but not a fix.

The software version doesnt claim nothing about this.
