When two switches are connected through fibers in a crossed way, two or three ports may be in the

disable state, and the rest in the inactive state.

When a fiber is connected to a device correctly on one end with the other end connected to no device:

If the device operates in the normal DLDP mode, the end that receives optical signals is in the

advertisement state; the other end is in the inactive state.

If the device operates in the enhance DLDP mode, the end that receives optical signals is in the

disable state; the other end is in the inactive state.

# Restore the ports taken down by DLDP

[SwitchA] dldp reset

2) Configure Switch B

The configuration of Switch B is the same to that of Switch A.
