18.3. SNMP Statistics
The show snmp statistics command can be very useful in determining if the switch is sending any traps. If the
switch is sending traps but the workstation is not receiving them, the workstation may have an issue (for
example, Windows firewall) or the IP address is not configured correctly, or user id, etc, on the switch.
Each MIB object displayed in the show snmp statistics command output is listed with a counter value.
For example:

By default the switch assigns UDP Port 1162 for the SNMP traps to be sent to the SNMP network
management station, but the NMS station might be listening to some other port for the traps. Make sure that
the switch matches with the NMS's port setup using the show snmp station command.
