Access Groups
(SNMPv1, SNMPv2c, or SNMPv3), and security level (no-authorization-no privacy,
authorization-no-privacy, or privacy).
An access group, in essence, is a template which defines a combination of access
privileges and views. A group can be associated to one or more network users to control
their access privileges and views.
When configuring access groups, the "no-security" view is generally recommended over
the "iso" view in order to restrict access to security objects.
A set of system-provisioned access groups and system-created communities are available
in SR OS. The system-provisioned groups and communities that begin with "cli-" are only
used for internal CLI management purposes and are not exposed to external SNMP access.
Additional access parameters must be explicitly configured if the preconfigured access
groups and views for SNMPv1 and SNMPv2c do not meet your security requirements.
