Type B protection provides redundant protection for both OLT PON ports and backbone fibers when OLT or OLT PON If the port or trunk fiber fails, manually switch to another – luguang.
On the U2000 network management, the oLT PON port LED is not green, indicating that the PON port is faulty.
(Radio) The downstream effective bandwidth of the GPON PON port is
OLT can support direct replication of user packet priority as the priority of forwarding packets, and also supports direct local configuration
When the Type C dual home protection linkage uplink detection, if the OLT or OLT uplink fails, the Type C dual home protection can be reversed to another OLT
(Multi-select) VLAN planning principles need to be considered
Max-Forwards fields can be used in S1P messages to solve loop problems and avoid endless packet forwarding.
Layer 2 enables IGMP-snooping , and when the switch port receives an IGMP join packet, it listens for the packet and adds the corresponding port to the multicast group
The scope of protection of the (multiple choice) GPON Type B dual attribution protection includes
(Multiple select) When there is a backbone fiber break or OLT does not detect the expected optical signal (L0S) alarm, the possible cause is that
