3.7.3 Duplex configuration mode of FastEthernet
The duplex mode of FastEthernet executed through self-negotiation as well as configuration on
interface.
Command
duplex half
duplex full
Duplex(default)
Choose the item 13 of prompt, it will display that:
U(undo) D(default) Q(quit)
(00)full
(01)half
Please Input the code of command to be excute(0-1):
Input 1, choose the item "half" can set it into half-duplex mode.
Input 0, choose the item "full" can set it into full-duplex mode.
Input D or d, it will come back to default settings.
3.7.4 Configure Ethernet subinterface
This section is description about the process of Ethernet sub-interface configuring. D-Link Router
supports the iEEE 802.1Q protocol on the Ethernet sub-interface. Detailed configuration as below:
1. Assign the sub-interface of Ethernet
Input following commands under the global mode to enter the status of Ethernet interface configuring:
interface
slot/port.subinterface-number
interface
slot/port.subinterface-number
Input the command "interface", it will list all the parameters:
(00)FastEthernet
(01)Ethernet
(02)Serial
......
Please Input the code of command to be excute(0-10): 1
Input 1, choose the item "Ethernet", it will prompt:
Please input a interface name:
Input the name of Ethernet, slot and port and the value of sub-interface-number.
Input 0, choose the item "Fast Ethernet", it will prompt:
Please input a interface name:
Input the name of Fast Ethernet, slot and port and the value of sub-interface-number.
2. Encapsulate 802.1Q protocol
The sub-interface of Ethernet must encapsulate with 802.1Q protocol for usage. Otherwise, UP is
unavailable for the protocol.
Set the operational mode of FastEthernet as half-duplex.
Set the operational mode of FastEthernet as full-duplex.
Restore the default setting as self-negotiation.
Force full duplex operation
Force half duplex operation
