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 send.
The group maps its users to views based on the security model and level with which the user is
communicating with the switch. Within a group, the following combinations of security model
and level can be mapped to views:
●
SNMPv1 - Only requests using SNMPv1 or higher.
●
SNMPv2c - Only requests using SNMPv2 or higher.
●
NoAuthNoPriv - An SNMPv3 user using the NoAuthNoPriv security level.
●
AuthNoPriv - An SNMPv3 user using the AuthNoPriv security level.
●
AuthPriv - An SNMPv3 user using the AuthPriv security level.
If a group with the specific security model and level does not exist, then a user can access a
group with lower security model or level. If an SNMPv3 group with NoAuthNoPriv security level
is not defined, SNMPv3 users with a NoAuthNoPriv security level can access the SNMPv2c
view.
To create an SNMPv3 group, you must provide the following information:
●
GroupName - String of up to 32 characters representing the name of the group.
●
Security model:
- SNMPv1
- SNMPv2c
- SNMPv3
●
Security level (for SNMPv3 only):
- NoAuthNoPriv
