Updated software on 2950 did help, at least since the upgrade I did not
have any problem with these weird trap parsing errors on 2950. But now
I'm getting the same stuff with 2960 switch. The mac-violation trap
comes and it's parsed by PF:

Again, "Wrong Type (should be INTEGER)" error.
This a 2960 switch with software 12.2(35)SE5 firmware:
Cisco IOS Software, C2960 Software (C2960-LANBASE-M), Version
12.2(35)SE5, RELEASE SOFTWARE (fc1)
... and this matches Catalyst_2960.pm's reqirement of "The minimum
required firmware version is 12.2(25)SEE2."
Any ideas what's wrong?
