Configure sub-interfaces of Ethernet interface

1Create and delete Ethernet sub-interfaces Please use the following commands in all views.

Table 190 Create and delete Ethernet interface

Operation	Command
Create Ethernet sub-interface and enter its view	interface ethernet
	number.sub-number
Delete the specified Ethernet sub-interface	undo interface ethernet
	number.sub-number

When using the above commands, if corresponding Ethernet sub-interface has been created (the same as sub-number), enter the view of this sub-interface directly. Otherwise, first create Ethernet sub-interface with sub-numberas the specified one, and then enter the view of this sub-interface.

2Configure relevant working parameters

If the sub-interface of Ethernet has not been configured with VLAN id, it can only support IPX network protocol. Therefore, only IPX network address and other IPX working parameters can be configured on this sub-interface. After configured with VLAN id, the sub-interface of Ethernet can support IP and IPX. The detailed configuration procedure and method are similar to those of the Ethernet interface. Please refer to Chapter 9 “Configuring LAN Interface” and Chapter 20 “Configuring IP Address”.

Configure sub-interfaces of WAN interface which link layer protocol is frame relay

1Create and delete WAN sub-interfaces

Please use the following commands in all views.

Table 191 Create and delete WAN sub-interface

Operation	Command
Create WAN sub-interface and enter its view	interface serial
	number.sub-number [ multipoint
	point-to-point ]
Delete specified WAN sub-interface	undo interface serial
	number.sub-number [ multipoint
	point-to-point ]

When using the above commands, if corresponding WAN sub-interface has been created (the same as sub-number), enter the view of this sub-interface directly. Otherwise, first create WAN sub-interface with sub-numberas the specified one, and then enter the view of this sub-interface.

2Configure relevant working parameters

The following items can be configured on the sub-interface of WAN interface which link layer protocol is frame relay:

■Frame relay address mapping which is different from the affiliated WAN interface (i.e. the main interface)

■IP address which is not in the same network segment as the affiliated WAN interface
