Configuring the duplex mode and speed of an
Ethernet interface
To make sure that DLDP works correctly on a link, you must configure the full duplex mode for the ports
at two ends of the link, and configure a speed for the two ports, rather than letting them negotiate a
speed.
To configure the duplex mode and speed of an Ethernet interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface
view.
interface interface-type
interface-number
N/A
3. Set the duplex mode. duplex full
Optional.
By default, full for a 10-GE interface,
and auto for other Ethernet interfaces.
4. Set the port speed. speed { 10 | 100 | 1000 } Optional.
For more information about the duplex and speed commands, see Ethernet interface configuration
commands in the Interface Command Reference.
Enabling DLDP
IMPORTANT:
Before enabling DLDP, make sure that optical fibers or copper twisted pairs are connected, because DLDP
can detect unidirectional links only after all physical links are connected.
To correctly configure DLDP on the switch, first enable DLDP globally, and then enable it on each port.
To enable DLDP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable DLDP globally. dldp enable Globally disabled by default.
3. Enter Ethernet port view or
port group view.
• Enter Ethernet port view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
Configurations made in Ethernet
port view apply to the current port
only. Configurations made in port
group view apply to all ports in the
port group.
4. Enable DLDP. dldp enable Disabled on a port by default.
NOTE:
DLDP takes effect only on Ethernet interfaces (optical or copper).
