A Switch 4200G 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 used by SNMP agents and the
UDP port used by SNMP trap respectively.
Executing the undo snmp-agent command disables the SNMP agent and closes UDP ports used
by SNMP agent and SNMP trap as well.
Use the command...
