or 100Mbps.
Broadcast Storm
reaches the broadcast storm rising or falling threshold.
MIBs
Management information and counters are stored in the Switch in
the Management Information Base (MIB). The Switch uses the
standard
MIB-II
Consequently, values for MIB objects can be retrieved from any
SNMP-based network manager software. In addition to the standard
MIB-II, the Switch also supports its own proprietary enterprise MIB
as an extended Management Information Base. These MIBs may also
be retrieved by specifying the MIB's Object-Identity (OID) at the
network manager. MIB values can be either read-only or read-write.
Read-only MIBs variables can be either constants that are
programmed into the Switch, or variables that change while the
Switch is in operation.
number of ports and types of ports. Examples of read-only variables
are the statistics counters such as the number of errors that have
occurred, or how many kilobytes of data have been received and
forwarded through a port.
