Issue that communication partially fails on logical link (colocation_logical_link) created in Colocation Inter-Connectivity menu.
When this issue occurs, Via the logical colocation link created on the physical colocation link of the Colocation Inter-Connectivity menu Only certain packets (such as PVST+/Rapid PVST+ BPDU packets, etc.) have problems in forwarding.
As a result, when PVST+ and Rapid PVST+ are used on the network device in the customer colocation rack, an interface that is in the Forwarding status may be in the Blocking status, and communication may not be possible. (It does not affect the existing logical link.)
Please delete and re-create the logical link (colocation_logical_link).
