SNMP MIB
SNMP is the protocol used to communicate TM 3.1 IP Trunk 3.01 (and later)
alarms or events. Support for the SNMP Management Information Bases
(MIB) on the IP trunk card is composed of two parts: the standard MIB-2
and extensions for the IP trunk card.
MIB-2 support
Support of MIB-2 is enabled by the use of the WindRiver SNMP agent,
WindNet©. The WindNet© agent supports the following MIB-2 groups:
•
system
•
interfaces
•
