Avaya G450 - Groups

SNMP versions
Issue 1 January 2008 331
Groups
In SNMPv3, each user is mapped to a group. The group maps its users to defined views. These
views define sets of access rights, including read, write, and trap or inform notifications the
users can receive.
The group maps its users to views based on the security model and level with which the user is
communicating with the G450. Within a group, the following combinations of security model and
level can be mapped to views:
● SNMPv1 security model and NoAuthNoPriv security level
● SNMPv2c security model and NoAuthNoPriv security level
● SNMPv3 security model and NoAuthNoPriv security level
● SNMPv3 security model and AuthNoPriv security level
● SNMPv3 security model and AuthPriv security level
If views are not defined for all security models and levels, a user can access the highest level
view below the user’s security level. For example, if the SNMPv1 and SNMPv2c views are
undefined for a group, anyone logging in using SNMPv1 and SNMPv2c cannot access the
device. If the NoAuthNoPriv view is not defined for a group, SNMPv3 users with a
NoAuthNoPriv security level can access the SNMPv2c view.
The G450 includes the following pre-configured groups:
