slTestsIfLoopType

Module: SL-TESTS-MIB

OID (symbolic): SL-TESTS-MIB::slTestsIfLoopType

OID (numeric): 1.3.6.1.4.1.4515.1.3.13.1.1.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The loopback type: facility The received signal at this interface is looped back out through the corresponding transmitter in the return direction. terminal The signal that is about to be transmitted is connected to the associated incoming receiver. prbs send and recieve prbs pattern. otnPrbs send and receive OTN prbs

What is slTestsIfLoopType?

This selects the type of loopback to perform on the interface: facility, terminal, PRBS pattern testing, or OTN PRBS testing. Admins choose facility loopback to test the far-end link by reflecting received signal back out, or terminal loopback to test local equipment by looping the outgoing signal back to the local receiver, while PRBS modes actively test for bit errors. To verify a suspect fiber span for bit errors, an admin would set slTestsIfLoopType to prbs(3) rather than a simple facility or terminal loop.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4515.1.3.13.1.1.1.5
snmpwalk -v2c -c public <target> SL-TESTS-MIB::slTestsIfLoopType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4515.1.3.13.1.1.1.5.1
snmpget -v2c -c public <target> SL-TESTS-MIB::slTestsIfLoopType.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4515.1.3.13.1.1.1.5.1 i <value>
