The system view is displayed.
Step 2 Run:
dldp enable
DLDP is enabled globally.
Step 3 Run:
interface interface-type interface-number
The Ethernet interface view is displayed.
Or run:
port-group port-group-name
The interface group view is displayed.
Step 4 Run:
dldp enable
DLDP is enabled on the interface.
By default, DLDP is disabled globally and on each interface.

1.2.3 (Optional) Setting the Operating Mode of DLDP
Context
If DLDP works in normal mode, the system can identify only one type of unidirectional link,
that is, the crossed connection of fibers. In this mode, the system does not use any timer, so it
cannot detect that a bidirectional link changes to a unidirectional link.
If DLDP works in enhanced mode, the system can identify two types of unidirectional links,
that is, the crossed connection of fibers and the connection where one fiber is disconnected. To
detect the unidirectional link caused by disconnection of one fiber, you need to manually set the
rate and full-duplex mode of the interconnected ports; otherwise, DLDP does not take effect
even if it is enabled. When a bidirectional link changes to a unidirectional link, the port where
the Tx fiber receives optical signals is in Disable state, and the port where the Tx fiber receives
no optical signals is in Inactive state.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
dldp work-mode { enhance | normal }
The operation mode of DLDP is set.
By default, the operation mode of DLDP is enhance mode.
