SNMP Agent and MIB-2 (RFC 1213)

The SNMP Agent running on the switch manager CPU is responsible for:

-

Retrieving MIB counters from various layers of software modules according to the SNMP GET/GET NEXT frame messages.

-

Setting MIB variables according to the SNMP SET frame message.

-

Generating an SNMP TRAP frame message to the Network Management Station if the threshold of a certain MIB counter is
reached or if other trap conditions (such as the following) are met:

WARM START

COLD START
LINK UP

LINK DOWN
AUTHENTICATION FAILURE

RISING ALARM
FALLING ALARM

TOPOLOGY ALARM

MIB-II defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-II covers all
manageable objects from layer 1 to layer 4, and, as a result, is the major SNMP MIB supported by all vendors in the
networking industry. The switch supports a complete implementation of SNMP Agent and MIB-II.
