Information
In order to configure the router to send SNMP notifications, you must enter at least one snmp-server
host command. If you enter the command with no keywords, all trap types are enabled for the host. If
you do not enter an snmp-server host command, no notifications are sent.
In order to enable multiple hosts, you must issue a separate snmp-server host command for each host.
You can specify multiple notification types in the command for each host.
When multiple snmp-server host commands are given for the same host and type of notification (trap
or inform), each succeeding command overwrites the previous command. Only the last snmp-server
host command will be in effect. For example, if you enter an snmp-server host inform command for
a host and then enter another snmp-server host inform command for the same host, the second
command will replace the first.
auth

without encryption.
