The latching loopback should be applied for each interface or EFP. Latching loopback is not supported on the Trunk EFP. Latching loopback is not supported for LAG interface.ДЁ02.1ad is not supported in latching loopback. Latching loopback is supported only on the RSP2 module. Latching Loopback Active-The loopback is currently active. Latching Loopback Inactive-Loopbacks are permitted, but there is no loopback request currently active. LLMs addressed to a specific LLSM are discarded. Latching Loopback Prohibited-Loopbacks are prohibited by an administrative action. The controller should be MEP and the responder may be an MEP or MIP. The LLSM is associated with a single MEP only and can activate the corresponding direction of loopback alone. The Latching loopback direction depends on the MEP direction:Дown-MEP refers to the External direction The messages received at a MIP correspond to either an internal or external loopback depending on which direction Received through an Up MEP correspond to internal loopbacks and the messages received through a Down MEP correspond to external In both directions, the LLSM uses an LLF within the LLD implementing the port being looped back. The Latching Loopback supports two directions for a port the internal loopbacks and the external loopbacks for a port. The controller node sends LLM and the responder node sends LLR. The Latching Loopback is used within a system that consists of the Ethernet Test Equipment (ETE) that acts as a Latching LoopbackД¬ontroller the CEN that forwards the Latching Loopback Messages (LLMs), the Latching Loopback Replies (LLRs), and the EthernetДЇrames that are looped back and the Network Element (NE) or ETE acting as a Latching Loopback Responder that incorporates The Latching Loopback Responder executes latching loopback at an External Interface (EI) in a Latching Loopback Function (LLF),ДЄt the boundary between a CEN and an External Network. Loopback to a Latching Loopback Responder, and supplies the Ethernet frames to be looped back by the Latching Loopback Responder. The Latching Loopback Controller that provides an inline control of the Latching Loopback State Machine (LLSM) initiates latching The Latching Loopback Function is referred as a Latching Loopback Device (LLD). The Latching Loopback Function (LLF) is deployed in the UNI and ENNI locations in various Carrier Ethernet equipments suchДЄs Network Interface Devices (NIDs), bridges, switches, and Ethernet Test Equipment (ETE). The Latching Loopback eliminates the need for peer to interoperate ProviderвЂ™s network initiates the Latching Loopback in the Access ProviderвЂ™s NID and then perform end-to-end testing based Point-to-point and multipoint services across multiple Carrier Ethernet Networks (CENs). Latching Loopbacks (LLs) are used for Service Activation Testing (SAT) and troubleshooting up to the information rate for Configuration Examples for Configuring Latching Loopback.
