DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Usage Guideline Use this command to start a LM test on an MEP. It will result in the MEP periodically sending an LMM message to a remote MEP. The system will calculate the far-end Frame Loss Ratio (FLR) and near-end FLR based on the received LMR messages. User can abort the frame loss measurement test by disable frame loss measurement function on the MEP. Some limitations of the counters should be noticed when the user uses the frame loss measurement function. • In the shared (MP-t-MP) Ethernet connection for devices, unknown unicast frames, broadcast frames, multicast frames transmitted from remote MEP to Up MEP or transmitted from Down MEP to remote MEP may not be counted; • The protocol PDUs which are processed by the software of the device may not be counted for devices. • ETH-LM and ETH-DM functions need to consume the ACL resources for devices. The user should notice that when enable ETH-LM or ETH-DM function on too many MEPs. Example This example shows how to start the LM test.
