• Security Model —Select the SNMP version attached to the group, SNMPv1,
v2, or v3.
Three types of views with various security levels can be defined. For each
security level, select the views for Read, Write and Notify by entering the following
fields:
• Enable —Select this field to enable the Security Level.
• Security Level —Define the security level attached to the group. SNMPv1
and SNMPv2 support neither authentication nor privacy. If SNMPv3 is
selected, choose one of the following:
- No Authentication and No Privacy —Neither the Authentication nor the
Privacy security levels are assigned to the group.
- Authentication and No Privacy —Authenticates SNMP messages, and
ensures the SNMP message origin is authenticated but does not encrypt
them.
- Authentication and Privacy —Authenticates SNMP messages, and
encrypts them.
• View —Associating a view with the read, write, and notify access privileges
of the group limits the scope of the MIB tree to which the group has read,
write, and notify access.
- View —Select a previously-defined view for Read, Write and Notify.
- Read —Management access is read-only for the selected view.
Otherwise, a user or a community associated with this group is able to
read all MIBs except those that control SNMP itself.
- Write —Management access is write for the selected view. Otherwise, a
user or a community associated with this group is able to write all MIBs
except those that control SNMP itself.
- Notify —Limits the available content of the traps to those included in the
selected view. Otherwise, there is no restriction on the contents of the
traps. This can only be selected for SNMPv3.
