Traps
Traps are messages that alert network personnel of events that occur on the Switch. The events can be as serious as a
reboot (someone accidentally turned OFF the Switch), or less serious like a port status change. The Switch generates
traps and sends them to the trap recipient (or network manager). Typical traps include trap messages for Authentication
Failure, Topology Change and Broadcast\Multicast Storm.
Management Information Base (MIB)
The Switch in the Management Information Base (MIB) stores management and counter information. The Switch uses the
standard MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved from any
SNMP-based network management software. In addition to the standard MIB-II, the Switch also supports its own
proprietary enterprise MIB as an extended Management Information Base. The proprietary MIB may also be retrieved by
specifying the MIB Object Identifier. MIB values can be either read-only or read-write.
