Defining SNMP Parameters

Simple Network Management Protocol (SNMP) provides a method for managing network devices. The switch supports the following SNMP versions:

SNMPv1 (version 1)

SNMPv2 (version 2)

SNMPv3 (version 3)

SNMP v1 and v2

The SNMP agents maintains a list of variables, which are used to manage the switch. The variables are defined in the Management Information Base (MIB). The MIB presents the variables controlled by the agent. The SNMP agent defines the MIB specification format, as well as the format used to access the information over the network. Access rights to the SNMP agents are controlled by access strings.

SNMPv1 and v2 are enabled by default.

SNMP v3

SNMP v3 also applies access control and a new traps mechanism to SNMPv1 and SNMPv2 PDUs. In addition, a User Security Model (USM) is defined for SNMPv3, which includes:

Authentication — Provides data integrity and data origin authentication.

Privacy — Protects against disclosure message content. Cipher Block-Chaining (CBC) is used for encryption. Either authentication is enabled on an SNMP message, or both authentication and privacy are enabled on an SNMP message. However privacy cannot be enabled without authentication.

Timeliness — Protects against message delay or message redundancy. The SNMP agent compares incoming message to the message time information.

Key Management — Defines key generation, key updates, and key use.
