sonetPortLoopback

Module: PORT-MIB

OID (symbolic): PORT-MIB::sonetPortLoopback

OID (numeric): 1.3.6.1.4.1.5812.3.5.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The types of loopback available on the SONET interface.

What is sonetPortLoopback?

This selects among several SONET loopback modes, including line-side loopbacks (slle, sllben), a section-side loopback (sdle), a path-side loopback (pdle), or none for normal operation. A technician uses the specific loopback type appropriate to the layer they're testing, since SONET's layered structure means a section loopback tests different circuitry than a path loopback. As with other loopback settings in this MIB, any value other than none takes the port out of normal service.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.3.5.1.4
snmpwalk -v2c -c public <target> PORT-MIB::sonetPortLoopback

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.3.5.1.4.1
snmpget -v2c -c public <target> PORT-MIB::sonetPortLoopback.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5812.3.5.1.4.1 i <value>
