security model and security level used to request access. In this way, VACM allows you to permit
or deny access to any individual item of management information depending on a user's group
membership and the level of security provided by the communications channel.
Configuring SNMP
This section provides the following information about configuring SNMP on Enterasys devices:
Configuration Basics
Completing an SNMP configuration on an Enterasys device involves defining users who will be
authorized to receive SNMP notifications about network events, associating security (target)
parameters, access rights and MIB views to those users, and specifying an IP address where they
will receive notifications. The basic steps in this process are:
1. Creating a name that will act as an SNMP user password:
–This will be a community name for an SNMPv1 or v2c configuration, or.
–A user name for an SNMPv3 configuration.
2. Creating a group for the user named in Step 1.
3. Creating access rights for the user group named in Step 2.
4. Defining MIB view(s) for the user group.
5. Creating a target parameters entry to associate security and authorization criteria to the users
created in Step 1.
6. Verifying if any applicable SNMP notification entries exist, or creating a new one. You will use
this entry to send SNMP notification messages to the appropriate targets configured in Step 5.
7. Creating a target address entry to bind a management IP address to:
– The notification entry and tag name created in Step 6, and
– The target parameters entry created in Step 5.
How SNMP Processes a Notification Configuration
In order to send a trap or inform notification requested by a MIB code, the SNMP agent requires
the equivalent of a trap “door”, a “key” to unlock the door, and a “procedure” for crossing the

Note: Commands for configuring SNMP on Enterasys devices are independent during the SNMP
setup process. For instance, target parameters can be specified when setting up optional
notification filters — even though these parameters have not yet been created with the set snmp
targetparams command. The steps in this section are a guideline to configuring SNMP and do not
necessarily need to be executed in this order.
