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.
