SNMP Commands
4-113

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 (page 4-116).

Command Usage
• An SNMP engine is an independent SNMP agent that resides either on this
switch or on a remote deivce. This engine protects against message replay,
delay, and redirection. The engine ID is also used in combination with user
passwords to generate the security keys for authenticating and encrypting
SNMPv3 packets.
