added or removed.

Command Usage
◆ If you do not enter an snmp-server enable traps command, no notifications
controlled by this command are sent. In order to configure this device to send
SNMP notifications, you must enter at least one snmp-server enable traps
command. If you enter the command with no keywords, both authentication
and link-up-down notifications are enabled. If you enter the command with a
keyword, only the notification type related to that keyword is enabled.
◆ The snmp-server enable traps command is used in conjunction with the
snmp-server host command. Use the snmp-server host command to specify
which host or hosts receive SNMP notifications. In order to send notifications,
you must configure at least one snmp-server host command.
◆ The authentication, link-up, and link-down traps are legacy notifications, and
therefore when used for SNMP Version 3 hosts, they must be enabled in
conjunction with the corresponding entries in the Notify View assigned by the
snmp-server group command.
Example
Console(config)#snmp-server enable traps link-up-down
