Description: Port PHY layer loopback. RX loopback is a loopback forwarding ingress traffic from RX port directly to TX port. TX loopback is a loopback forwarding egress traffic from TX port directly to RX port, TX loopback is not supported in I-NNI ports. The RX/TX loopback can only be enabled when the port admin-state is disabled. Enable an RX/TX loopback shall fail when the port has its admin-state enabled. Users shall be able to disable the xcvr/ptp when its child port loopback enabled. Enable xcvr/ptp shall not enable its child port with loopback enabled. A port shall has its operational state rx loopback when rx loopback is enabled, and tx loopback when tx loopback is enabled.
What is cwsPortPropertiesLoopback?
Controls or reports the PHY-layer loopback mode on the port (RX loopback sends ingress traffic straight back out on TX, TX loopback sends egress traffic back in on RX), used for diagnostic testing; TX loopback cannot be used on I-NNI ports and loopback can only be enabled under certain port conditions.
