Hello folks, please help me in resolving the issue. I get this error message twice a week resulting in complete network failure with 2 ISP's connected to this stack switch
%SSH-4-SSH2_UNEXPECTED_MSG: Unexpected message type has arrived. Terminating the connection
The switch version is /c3750e-universalk9-mz.122-55.SE1
Has it got any thing to do with this version? Do I need to upgrade it to 15.4?
Regards,
Hashmi

ok so this is at the front of the network yes the 2 ISP circuits are directly connected to this 3750 , your not crossing any other devices that ping may stop at ?
can you post the show tech off the switch really need to see what happening here if there is anything else going on
if you cant and your certain ssh is causing this upgrade the switch to test as a fix , if its dropping off 3 times a day you need to do something asap
I have never seen ssh to cause something like this that's way I think something else is dropping your connection but bugs can do weird things , a software upgrade will rule it out
