A Switch 5500-EI 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.
