Description: An unique value for each Token Ring subsystem. Its value ranges between 1 and 'chNumSlots' defined in chassis-mib.txt.

What is ctronFnbTRIndex?

A unique per-subsystem index identifying a Token Ring board in the chassis, ranging from 1 up to the chassis's chNumSlots value. Admins use this index to correlate a specific Token Ring subsystem's FNB, or Flexible Network Bus, connection status entries with its physical slot in the chassis. ctronFnbTRIndex value 3 on a chassis with 8 slots identifies the Token Ring board installed in slot 3.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.1
snmpwalk -v2c -c public <target> CTRON-FNBTR-MIB::ctronFnbTRIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.6.1.1.1.1.1.1
snmpget -v2c -c public <target> CTRON-FNBTR-MIB::ctronFnbTRIndex.1
