vdsx1TrunkLoopback

Module: VERTICALT1-E1-MIB

OID (symbolic): VERTICALT1-E1-MIB::vdsx1TrunkLoopback

OID (numeric): 1.3.6.1.4.1.2338.3.2.1.19

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable represents the loopback confi- guration of the DS1 interface. Agents support- ing read/write access should return badValue in response to a requested loopback state that the interface does not support. The values mean:

vdsx1NoLoop Not in the loopback state. A device that is not capable of performing a loopback on the interface shall always return this as it's value.

vdsx1PayloadLoop The received signal at this interface is looped through the device. Typically the received signal is looped back for re- transmission after it has passed through the device's framing function.

vdsx1LineLoop The received signal at this interface does not go through the device (minimum pene- tration) but is looped back out.

vdsx1OtherLoop Loopbacks that are not defined here.

What is vdsx1TrunkLoopback?

This read-write value configures the DS1 interface's loopback state: 'vdsx1NoLoop' (normal operation), 'vdsx1PayloadLoop' (received signal looped back after passing through framing), 'vdsx1LineLoop' (received signal looped back before reaching the device, minimum penetration), or 'vdsx1OtherLoop'. An admin sets a line or payload loopback to isolate whether a suspected fault is on the near-end equipment or further out on the circuit, and the device returns badValue if an unsupported loopback state is requested.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2338.3.2.1.19
snmpwalk -v2c -c public <target> VERTICALT1-E1-MIB::vdsx1TrunkLoopback

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2338.3.2.1.19.1
snmpget -v2c -c public <target> VERTICALT1-E1-MIB::vdsx1TrunkLoopback.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2338.3.2.1.19.1 i <value>
