158 CHAPTER 11: CONFIGURING LOGICAL INTERFACE
Configure sub-interfaces of Ethernet interface
1 Create and delete Ethernet sub-interfaces
Please use the following commands in all views.
Table 190 Create and delete Ethernet interface
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-number as the
specified one, and then enter the view of this sub-interface.
2 Configure 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
1 Create and delete WAN sub-interfaces
Please use the following commands in all views.
Table 191 Create and delete WAN sub-interface
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-number as the specified one,
and then enter the view of this sub-interface.
2 Configure 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
Operation Command
