Note: Each VLAN interface is created on top of only one Ethernet interface.
Otherwise, VLAN interfaces are similar to other interfaces in many ways. They have an IP address,
subnet mask, and gateway used to make routing decisions. They restrict bandwidth and packet
size. They can provide DHCP services, and they can verify the gateway is available.

Name This field displays the name of the interface.
Port/VID For VLAN interfaces, this field displays
• the Ethernet interface on which the VLAN interface is created
• the VLAN ID
For virtual interfaces, this field is blank.
IP Address This field displays the current IP address of the interface. If the IP address is 0.0.0.0, the
interface does not have an IP address yet.
This screen also shows whether the IP address is a static IP address (STATIC) or dynamically
assigned (DHCP). IP addresses are always static in virtual interfaces.
Mask This field displays the interface’s subnet mask in dot decimal notation.
