SNMP Overview
The switch supports the SNMPv1, SNMPv2 and SNMPv3.
SNMP v1 and v2
The SNMP agent maintains a list of variables that are used to manage the
switch. These variables are stored in the Management Information Base
(MIB) from which they may be presented. 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
In addition to the features provided by SNMPv1 and SNMPv2, SNMPv3
applies access control and a new trap mechanism to SNMPv1 and SNMPv2
PDUs. In addition, a User Security Model (USM) can be defined, which
includes:
• Authentication — Provides data integrity and data origin authentication.
