Common test indicators for Ethernet services are:

When the standard Ethernet frame length of 64Byte signal is connected to the Ethernet board, if the QinQ function is enabled Yes, what is the actual frame length of the signal inside the board () Byte? 

(Judgment) Both SC2 single board and ST2 single board support 1588V2 signal processing and transparent transmission.

In the scenario of non-convergent OUT processing SDH standard signals, both A and B are WDM stations, and A station OTU The R_LOS alarm is detected on the client side of OUT, and after processing the alarm on the WDM side of OUT, in the downstream B The client side of the station detects and reports the REM_SF alarm, and station B transmits the signal to its downstream client equipment, and Report the R_LOS alarm to the client device. 

The key to NG WDM system fault location is to accurately locate the fault to a single station
