Configuring SNMP
Overview
Supported
versions of SNMP
The P580 and P882 support SNMPv1, v2, and v3.
SNMPv3 Security
Features
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.
