Greetings,
I have two Cat5000 with Supervisor Engine I running Sw version 2.4(5). Both
Cat5000 have trunking enabled on port 1/1. I have a spare Cat5000 that I
would like to add to the current network. This spare Cat5000 also has a
Supervisor Engine I but it runs Sw version 1.2.
The problem that I am experiencing is that if the Cat5000 spare is setup to
trunk with Cat5000-2, I can't ping to and from the Cat5000 spare. I have
tried disabling trunking and the problem still exist.
If I do "sh cdp neighbors" on the Cat5000-2, it shows the Cat5000 spare in
the list but only with T (transparent bridge) capability, whereas the
Cat5000-1 shows a capability of T (transparent bridge) and S (switch).
|---------| trunking |---------| no trunk |-------------|
|Cat5000-1|----------|Cat5000-2|----------|Cat5000 Spare|
|---------| |---------| |-------------|
I don't understand why the different Cat OS version would affect
connectivity between switches. Is there a special protocol (BPDU?) that are
running on the Cat5000 to ensure connectivity?
I would like to upgrade the 1.2 version to 2.4(5) on the spare there is not
enough space on the spare's flash. I will probably end up buying more RAM to
be able to put the 2.4(5) image on the spare Cat5000 but I can't find any
good explanation yet on why the different Cat OS version would not "talk" to
each other, trunking or no trunking.
Below are the "sh ver" output for all 3 Cat5000.
