Configuring SNMP
The P580 and P882 support SNMPv1, v2, and v3.
SNMP version 3 provides the following security features that SNMPv1 and
v2 do not provide:
Encryption of protocol data units (PDUs) to prevent unauthorized
users from viewing the PDU contents. SNMPv3 uses CBC-DES for
its encryption protocol.
Authentication of the user who sent the PDU. User authentication is
provided by either the HMAC-SHA or HMAC-MD5 authentication
protocol.
Timeliness checks of the PDU to ensure that it has not been delayed
or replayed.
Ability to define which MIB objects and table rows that specific
users can access and whether they have read-only, read-write, or
notify access. This functionality is achieved by creating views,
associating user groups with views, and then assigning users to
groups.
* Note: For security reasons, you no longer can view the snmp
configuration in the startup configuration file.
