What Is CTRON-FNBTR-MIB?

CTRON-FNBTR-MIB is a Cabletron Systems proprietary MIB reporting Token Ring subsystem connection status for the FNB (Flexible Network Bus) backplane architecture used in Cabletron MMAC-family chassis. Its table, indexed per Token Ring subsystem, reports left/right connection status and bypass/relay-point bypass state, with a parallel multi-FNB variant for chassis with more than one FNB backplane. As a hardware-status MIB it lets an administrator confirm a Token Ring module's backplane connections are intact and not bypassed. It is deployed on Cabletron MMAC-family chassis with Token Ring modules on an FNB backplane. Engineers can download the CTRON-FNBTR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-FNBTR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cabletron Systems MMAC-family chassis with Token Ring modules (FNB backplane)

Monitoring Examples

An administrator checks ctronFnbBypass for a Token Ring module reporting intermittent connectivity, confirming whether the module has been automatically bypassed on the FNB backplane due to a detected fault.

What Can Be Monitored

Token Ring module FNB connection and bypass status

OID symbolic	OID numeric	Type	Access	Description
ctronFnbTR	1.3.6.1.4.1.52.4.1.2.6.1.1
ctronFnbTRTable	1.3.6.1.4.1.52.4.1.2.6.1.1.1		not-accessible	A list of entries that provide connection status of Token Ring subsystems, for the FNB.
ctronFnbTREntry	1.3.6.1.4.1.52.4.1.2.6.1.1.1.1		not-accessible	An entry in the ctronFnbTRTable containing objects that provide FNB connection status for a Token Ring sub- system.
INT ctronFnbTRIndex	1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.1	INTEGER	read-only	An unique value for each Token Ring subsystem. Its value ranges between 1 and 'chNumSlots' defined in chassis-mib.txt.
INT ctronFnbConnectLeft	1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.2	INTEGER	read-write	Denotes the connection status of the Token Ring board to the left of the current one. An attempt to set a value of 1 or 4 will result in an error code of badValue.
INT ctronFnbConnectRight	1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.3	INTEGER	read-write	Denotes the connection status of the Token Ring board to the right of the current one. An attempt to set a value of 1 or 4 will result in an error code of badValue.
INT ctronFnbBypass	1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.4	INTEGER	read-write	Denotes the bypass status of the current Token Ring board.
INT ctronFnbRPBypass	1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.5	INTEGER	read-write	Denotes the Ring Port bypass status of the current Token Ring board. If this capability is not available on this board, the value 'other' is returned when read, and BADSETINFO when written.
ctronMultiFnbTR	1.3.6.1.4.1.52.4.1.2.6.1.2
ctronMultiFnbTRTable	1.3.6.1.4.1.52.4.1.2.6.1.2.1		not-accessible	A list of entries that provide connection status of Token Ring subsystems, for the FNB.
ctronMultiFnbTREntry	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1		not-accessible	An entry in the ctronMultiFnbTRTable containing objects that provide FNB connection status for a Token Ring sub- system.
INT ctronMultiFnbTRIndex	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.1	INTEGER	read-only	An unique value for each Token Ring subsystem. Its value ranges between 1 and 'chNumSlots' defined in chassis-mib.txt.
INT ctronMultiFnbRingIndex	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.2	INTEGER	read-only	An unique value representing an instance of an FNB ring path attachment. Its value ranges between 1 and n, where n equals the maximum number of FNB ring paths available in a given chassis. For an MMAC chassis with an FNB, this number is 4.
INT ctronMultiFnbConnectLeft	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.3	INTEGER	read-only	Denotes the connection status of the left attach circuitry for a particular FNB ring path attachment on this Token Ring oard.
INT ctronMultiFnbConnectRight	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.4	INTEGER	read-only	Denotes the connection status of the right attach circuitry for a particular FNB ring path attachment on this Token Ring board.
INT ctronMultiFnbBypass	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.5	INTEGER	read-write	Denotes the connection status of the bypass circuitry for a particular backplane ring path attachment on this Token Ring board.
INT ctronMultiFnbRPBypass	1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.6	INTEGER	read-write	Denotes the connection status of the ring port bypass circuitry for a particular backplane ring path attachment on his Token Ring board.
