11.2.2 Configuring the IP Address of the VLAN Interface
You can configure an IP address for every VLAN interface of the switch. Generally, it is
enough to configure one IP address for an interface. You can also configure ten IP
addresses for an interface at most, so that it can be connected to several subnets.
Among these IP addresses, one is the primary IP address and all others are secondary.
Perform the following configuration in VLAN interface view.
Table 11-3 Configure an IP address for a VLAN interface
Operation Command
Configure an IP address for a VLAN
interface
ip address ip-address { mask |
mask-length } [ sub ]

interface

By default, the IP address of a VLAN interface is null.
11.3 Displaying and debugging IP Address
After the above configuration, execute the display command in any view to display the
IP addresses configured on interfaces of the network device, and to verify the effect of
the configuration.
