cfd slm

Use cfd slm to enable loss measurement (LM). The LM function measures the frame loss between the source and target MEPs by using LMM frames and LMR frames.

Syntax

mep mep-id: Specifies the source MEP by its ID in the range of 1 to 8191.

target-mac mac-address: Specifies the target MEP by its MAC address, which is in the format of H-H-H.

target-mep target-mep-id: Specifies the target MEP by its ID in the range of 1 to 8191.

number number: Specifies the number of LMM frames to be sent. The value range for the number argument is 2 to 10, and the default is 5.

Examples
