When configuring i Ethernet Layer 2 attributes, when the "TAG ID" is set to "Accese" or "Hybrid", you need to set the "Default VLAN ID" and "VLAN Priority" of untagged frames. "VLAN Priority" should be set according to the unified QoS plan.
When a signal with a standard Ethernet frame length of 64Bytes is connected to the Ethernet board, if the QinQ function is enabled, what is the actual frame length of the signal inside the board () Bytes?
OTUk_ENC indicates that the OTUk bit error exceeds the threshold. What are the options for the following description of the bit error detection horizontal mode? (Multiple choice)
When performing fiber synchronization, the network management has not created a fiber, indicating that the fiber connection only exists on the physical network element side.
The essence of QPSK modulation is to select 4 possible values on the optical field phase, so that the baud rate can be reduced by half without reducing the line rate.
Both the Ping function and the Traceroute function detect the bidirectional connectivity of the tunnel and PW by exchanging MPLS echo request and MPLS echo reply messages.
The dispersion caused by the two orthogonal polarization states of signal light having different propagation speeds in the optical fiber is called polarization mode dispersion.
In a chain network, NE1, NE2, and NE3 are all OADM sites, and NE1 is a gateway network element, and uses OSC communication. When the optical monitoring board at the intermediate site NE2 fails, which of the following phenomena will not occur?
In an 80-wave system, using the TMB1DAP (TM150AC106) amplifier, the total input power is known to be -19~1 dBm. The typical gain is 19 D, what is the nominal single-wavelength output optical power?
