tnTtLoopConfigInstanceDirection

Module: TN-TT-LOOP-MIB

OID (symbolic): TN-TT-LOOP-MIB::tnTtLoopConfigInstanceDirection

OID (numeric): 1.3.6.1.4.1.868.2.5.149.3.1.4

Node type: OBJECT-TYPE

Type: TNTtLoopInstanceDirection

Access: read-write

Description: The instance direction. Currently Terminal Loop is only supported in EVC domain.

What is tnTtLoopConfigInstanceDirection?

This value sets the direction of the Traffic Test loop instance, noting that Terminal Loop direction is currently only supported within the EVC domain. An admin chooses the loop direction to control where in the traffic path the test signal is reflected back, relevant for isolating whether a fault lies upstream or downstream of the loop point. Setting tnTtLoopConfigInstanceDirection to Terminal Loop on a non-EVC-domain instance would fall outside the platform's currently supported combination.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.149.3.1.4
snmpwalk -v2c -c public <target> TN-TT-LOOP-MIB::tnTtLoopConfigInstanceDirection

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.149.3.1.4.1
snmpget -v2c -c public <target> TN-TT-LOOP-MIB::tnTtLoopConfigInstanceDirection.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.149.3.1.4.1 s <value>
