cmEthernetNetPortLoopbackStatus
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortLoopbackStatus
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.7.1.30
Node type: OBJECT-TYPE
Type: CmLoopbackType
Access: read-only
Description:
This object provides status of the current loopback on the Ethernet Network Port.
What is cmEthernetNetPortLoopbackStatus?
This OID shows the current loopback mode applied to an Ethernet network port on a cable modem or gateway, such as no loopback, local loopback, or remote loopback. When a port is in loopback mode, traffic is redirected to self-test the link without reaching the external network. Technicians use this to confirm that diagnostic loopback tests are active and monitor their status.
