Can two interface communicate with each other if one interface works in auto-negotiation mode and the other works in forcible mode

This configuration is not recommended. When this configuration is used, the interface working in auto-negotiation mode changes to half-duplex state according to the auto-negotiation requirements. This reduces the network utilization efficiency and may cause other problems.

It is strongly recommended that the local and remote interfaces work in the same mode. That is, they both work in auto-negotiation mode or forcible mode.
