ctronMultiFnbBypass

Module: CTRON-FNBTR-MIB

OID (symbolic): CTRON-FNBTR-MIB::ctronMultiFnbBypass

OID (numeric): 1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Denotes the connection status of the bypass circuitry for a particular backplane ring path attachment on this Token Ring board.

What is ctronMultiFnbBypass?

Controls the bypass circuitry for one specific FNB ring path attachment on a multi-ring Token Ring board, enabled(3) or disabled(2). Admins enable bypass on the specific ring path attachment being serviced, rather than the whole board, before removing that board, so only the affected ring path is bridged around, leaving other rings on the board unaffected. Setting ctronMultiFnbBypass to enabled(3) for ring path 1 on a given board while ring path 2 stays disabled(2) isolates just that one FNB ring during maintenance.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.5
snmpwalk -v2c -c public <target> CTRON-FNBTR-MIB::ctronMultiFnbBypass

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.5.1
snmpget -v2c -c public <target> CTRON-FNBTR-MIB::ctronMultiFnbBypass.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.2.6.1.2.1.1.5.1 i <value>
