A Switch 4210 provides the following functions to prevent attacks through
unused UDP ports.
Executing the snmp-agent command or any of the commands used to
■
configure SNMP agent enables the SNMP agent, and at the same opens UDP
port 161 and UDP port 1024 used by SNMP agents and SNMP trap clients
respectively.
Executing the undo snmp-agent command disables the SNMP function and
■
closes UDP port 161 and UDP port 1024 as well.
Trap messages are those sent by managed devices to the NMS without request.
They are used to report some urgent and important events (for example, the
rebooting of managed devices).
Note that basic SNMP configuration is performed before you configure basic trap.
