Table 23 Configure an Ethernet sub-interfaces
Operation
Create an Ethernet
sub-interface and enter the
Ethernet sub-interface view
By default, no VLAN is associated to sub-interfaces created by using the
■
interface command.
IP parameters and IPX parameters can be configured on Ethernet
■
sub-interfaces. Refer to the
"IPX Configuration" on page 2217
CAUTION: In terms of VLANs
An Ethernet sub-interface cannot send and receive packets properly before the
■
VLAN associated with the Ethernet sub-interface is activated.
The VLAN associated with the Ethernet sub-interface of the local device must
■
be the same as the VLAN associated with the Ethernet sub-interface of the
peer device. Otherwise, packets cannot be transmitted properly.
Display and maintain Ethernet sub-interfaces
After the above configuration, you can use the display command in any view to
view the configuration information of the Ethernet sub-interface, so as to verify
the configuration.
You can use the reset command in user view to clear the statistics on the VLAN
associated with the specified sub-interface.
