Authentication Key
—If the authentication method is either an MD5 or SHA
key, enter the MD5 or SHA authentication key.

be exactly 32 hexadecimal characters.
NOTE
If your security level is authNoPriv, you still need to enter a Privacy Key
value of 32 hexadecimal digits. However, the key will not be used.

Defining SNMP Communities
Access rights in SNMPv1 and SNMPv2 are managed by defining communities in
the
Communities
page. The community name is a type of shared password
between the SNMP management station and the device. It is used to authenticate
the SNMP management station.
Communities are only defined in SNMPv1 and v2 because SNMPv3 works with
users instead of communities. The users belong to groups that have access rights
assigned to them.
The
Communities
page
associates communities with access rights, either directly
(Basic mode) or through groups (Advanced mode):
•
Basic mode—The access rights of a community can configure with Read
Only, Read Write, or SNMP Admin. In addition, you can restrict the access to
the community to only certain MIB objects by selecting a view (defined in the
SNMP Views
page).
•
Advanced Mode—The access rights of a community are defined by a group
(defined in the
Groups
page). You can configure the group with a specific
security model. The access rights of a group are Read, Write, and Notify.
