Module: CTRON-COMMON-MIB

OID (symbolic): CTRON-COMMON-MIB::fnbTRIndex

OID (numeric): 1.3.6.1.4.1.52.1.6.1.2.1.1.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: An unique value for each Token Ring subsystem. Its value ranges between 1 and chassisSlots. The value for each interface must remain constant, at least, from one re-initialization of the entity's network management system to the next re-initialization.

What is fnbTRIndex?

This read-only integer uniquely identifies a Token Ring subsystem within the chassis, ranging between 1 and the number of chassis slots, and this value remains constant across management system reinitializations. An administrator uses this stable index to consistently reference a specific Token Ring module's slot position when correlating other Token Ring MIB data across reboots or management sessions. For example, when documenting which slot a particular Token Ring module occupies, the admin records this index value knowing it will remain the same after the next management system restart.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.1.6.1.2.1.1.1.1
snmpwalk -v2c -c public <target> CTRON-COMMON-MIB::fnbTRIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.1.6.1.2.1.1.1.1.1
snmpget -v2c -c public <target> CTRON-COMMON-MIB::fnbTRIndex.1
