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.
