RE: Timeout

With « term mon » ( Terminal monitor) + "debug snmp"  entered on the switch, you should get some messages on the switch.
Do you see some ?

Best regards

The port number isn't the problem.  To see what's happening on the
switch, get into enable mode on the switch & do
conf t
snmp-server community zuperZekret ro
end
term mon
debug snmp packets

Then from your PC do
snmpget -v 2c -c zuperZekret <ip address of switch> .1.3.6.1.2.1.1.5.0

that should give you enough information to figure out what the problem is
