Use the enable snmp trap updown command to enable the sending of port/interface linkUp/linkDown 

traps. 

Use the undo enable snmp trap updown command to disable the sending of linkUp/linkDown traps. 

By default, the sending of port/interface linkUp/linkDown traps is enabled. 

Note that you need to enable the generation of port/interface linkUp/linkDown traps both on the 

port/interface and globally if you want a port/interface to generate port/interface linkUp/linkDown traps 

when the state of the port/interface changes. 

To enable this function on a port/interface, use the enable snmp trap updown command; to enable 

this function globally, use the snmp-agent trap enable [ standard [ linkdown | linkup ] * ] command. 

By default, both are enabled. 

# Enable the port Ethernet 1/0/1 to send linkUp/linkDown SNMP traps to the NMS whose IP address is
