supports. If the snmp-server host command does not specify the SNMP
version, the default is to send SNMP version 1 notifications.
• If you specify an SNMP Version 3 host, then the community string is
interpreted as an SNMP user name. If you use the V3 “auth” or “priv” options,
the user name must first be defined with the snmp-server user command.
Otherwise, the authentication password and/or privacy password will not
exist, and the switch will not authorize SNMP access for the host. However, if
you specify a V3 host with the “noauth” option, an SNMP user account will be
generated, and the switch will authorize SNMP access for the host.

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
Console(config)#snmp-server host 10.1.19.23 batman
