Management information base (MIB)
As is normal for an SNMP manager system, each of the remotely-controllable
boards, frame and PSUs that are to be monitored have an associated MIB. Each
MIB is a collection of object identifiers that identify all variables that can be read via
SNMP and these MIBs are available from Crystal Vision. Use a MIB Browser to
view all status and control possibilities.
Object Identifiers (OID)
For each variable to be monitored there is an object identifier or OID which can be
distinguished from any other OID within the MIB tree by a unique number sequence
coded within the MIB. As an example, from the FrameMon MIB (see tree below),
the front panel status variable
isTempOK
is accessed by the OID
1.3.6.1.4.28681.1.2.1.150.1.4
. The OID will then be accompanied by a value to
indicate its status, in this case, 1= NO, 2= YES. Any status change will cause the
transmitting of a trap to the SNMP manager.
The following grab from a MIB Browser shows the FrameMon MIB tree with its
identifying number sequences:
