MIBs
Management Information Base (MIB) documents are defined by the IEEE
in “Requests For Comments” (RFCs). The core of the industry-standard
SNMP MIB, MIB II (RFC 1213), contains general variables relating to IP,
TCP, and UDP statistics for network devices such as repeaters, routers,
and gateways. The MIB II client is implemented as part of Omega. Each
MIB variable (managed object) has a value, either numeric or string (text).
These values are stored in registers or accumulators in the switch. Many
of these variables are counters that track network performance, e.g.,
errors or number of packets. Other variables regulate switch
configuration, e.g., “turn port X Off Line” or “Enable Link Test function.”
Your switch implements other related MIB extensions as well. For more
information on MIB definitions and documentation of each MIB object,
refer to IEEE MIB documentation. RFCs. Other RFCs that apply to the
switch include:
