The following description of the internal port attributes of the Ethernet board, which is wrong?A . Ingress port to Access property. If the input data has a VLAN ID, discard itB . For the ingress port of Tag Aware attribute, if the input data has a VLAN ID, the received...
NG WDM two-dimensional ROADM sites can use WSMD9 single board, and its signal flow is the optical signal connected to the main optical channel from the "IN" optical port. 9 channels of the same optical signal are broadcast through the RDU (ROADM Demix Unit) optical module and output from the "DM1~DM8" and "ECPO" optical ports. One of the signals is locally dropped by the demultiplexer board, and the other 8 signals are dispatched to the other 8 directions. Access the signals of the main optical channel from the "EXPI" optical port. The multiplexed or single-wave optical signals that need to be inserted locally are input through the "AM1" ~ "AM8" optical ports.
