j2LoopbackConfig

Module: Fore-J2-MIB

OID (symbolic): Fore-J2-MIB::j2LoopbackConfig

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.6.1.1.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable represents the loopback configuration of the J2 interface.

j2NoLoop (1) means that the interface is not in a loopback state.

j2LineLoop (2) means that receive signal is looped back for retransmission without passing through the port's reframing function.

j2DiagLoop (3) means that the transmit data stream is looped back to the receiver.

j2OtherLoop (4) means that the interface is in a loopback that is not defined here.

What is j2LoopbackConfig?

Puts this J2 interface into a loopback mode for testing: none (default), line loop (received signal looped back for retransmission before the reframer), diagnostic loop (transmit stream looped back to the receiver), or another vendor-specific loop.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.6.1.1.1.5
snmpwalk -v2c -c public <target> Fore-J2-MIB::j2LoopbackConfig

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.6.1.1.1.5.1
snmpget -v2c -c public <target> Fore-J2-MIB::j2LoopbackConfig.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.6.1.1.1.5.1 i <value>
