foreSonetVTLoopbackMode
Module: Fore-Sonet-Ext-MIB
OID (symbolic): Fore-Sonet-Ext-MIB::foreSonetVTLoopbackMode
OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.14.5.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This variable represents the current loopback status of the sonet interface. The possible values are: sonetVTNoLoop(1): interface is not in a loopback state. sonetVTLineLoop(2): data on the receive path is looped back on to the transmit path. sonetVTDiagLoop(3): data to be transmitted on the transmit path is looped back on to the receive path. sonetVTOtherLoop(4): the loopback mode is not defined here.
What is foreSonetVTLoopbackMode?
Sets or reports the loopback mode at the SONET Virtual Tributary layer: sonetVTNoLoop for normal operation, sonetVTLineLoop to loop received data onto the transmit path, sonetVTDiagLoop to loop transmit data onto the receive path, or sonetVTOtherLoop for a vendor-specific mode. It's the VT-layer equivalent of the medium and path loopback controls, used to isolate faults on a specific tributary.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.5.1.1.1 snmpwalk -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetVTLoopbackMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.5.1.1.1.1 snmpget -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetVTLoopbackMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.14.5.1.1.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> foreSonetVTLoopbackMode.1
