MIBs

Management and counter information 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 management 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. Examples of read-only constants are the
number of port and type of ports.
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.
Read-write MIBs
customized configurations. Examples of these are the Switch' s IP
Address, Spanning Tree Algorithm parameters, and port status.
If you use a third-party vendors' SNMP software to manage the
Switch, a diskette listing the Switch' s propriety enterprise MIBs
can be obtained by request. If your software provides functions to
