Usage
Information
In order to configure the router to send SNMP notifications, 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, 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 replaces the first command.
The snmp-server host command is used with the snmp-server enable command. Use the
snmp-server enable command to specify which SNMP notifications are sent globally. For a host to
receive most notifications, at least one snmp-server enable command and the snmp-server
host command for that host must be enabled.
NOTE: For v1 / v2c trap configuration, if the community-string is not defined using the snmp-
server community command prior to using this command, the default form of the snmp-server
community command automatically is configured with the community-name the same as specified in
the snmp-server host command.
Configuring Informs
To send an inform, use the following steps:
1. Configure a remote engine ID.
2. Configure a remote user.
3. Configure a group for this user with access rights.
4. Enable traps.
5. Configure a host to receive informs.
