Usage Information
In order to congure the router to send SNMP notications, 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 notications are sent.
In order to enable multiple hosts, issue a separate snmp-server host command for each host. You can
specify multiple notication types in the command for each host.
When multiple snmp-server host commands are given for the same host and type of notication (trap
or inform), each succeeding command overwrites the previous command. Only the last
snmp-server
host command will be in eect. 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 rst command.
The snmp-server host command is used with the snmp-server enable command. Use the snmp-
server enable command to specify which SNMP notications are sent globally. For a host to receive
most notications, at least one snmp-server enable command and the snmp-server host
command for that host must be enabled.
NOTE: For v1 / v2c trap conguration, if the community-string is not dened using the snmp-
server community command prior to using this command, the default form of the snmp-
server community command automatically is congured with the community-name the same
as specied in the snmp-server host command.
Conguring Informs
To send an inform, use the following steps:
1. Congure a remote engine ID.
2. Congure a remote user.
3. Congure a group for this user with access rights.
4. Enable traps.
5. Congure a host to receive informs.
