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-2 defines a set of manageable objects in various layers
of the TCP/IP protocol suites. MIB-2 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-2.
