SNMP Configuration Guidelines
An SNMP group is a table that maps SNMP users to SNMP views. An SNMP user is a member of an
SNMP group. An SNMP host is the recipient of an SNMP trap operation. An SNMP engine ID is a name
for the local or remote SNMP engine.
Note Before using alarm profiles to set the Catalyst 2955 switch to send SNMP alarm trap notifications to an
SNMP server, you must first enable SNMP by using the snmp-server enable traps alarms global
configuration command.
When configuring SNMP, follow these guidelines:

shows the default SNMP configuration.
When configuring an SNMP group, do not specify a notify view. The snmp-server host global
configuration command autogenerates a notify view for the user and then adds it to the group
associated with that user. Modifying the group's notify view affects all users associated with that
group. Refer to the Cisco IOS Configuration Fundamentals Command Reference for Release 12.1
for information about when you should configure notify views.
To configure a remote user, specify the IP address or port number for the remote SNMP agent of the
device where the user resides.
Before you configure remote users for a particular agent, configure the SNMP engine ID, using the
snmp-server engineID global configuration with the remote option. The remote agent's SNMP
engine ID and user password are used to compute the authentication and privacy digests. If you do
not configure the remote engine ID first, the configuration command fails.
When configuring SNMP informs, you need to configure the SNMP engine ID for the remote agent
in the SNMP database before you can send proxy requests or informs to it.
