This screen lets you configure IP address assignment, interface bandwidth 
parameters, DHCP settings, and connectivity check for each VLAN interface. To 
access this screen, click the Add icon at the top of the Add column or click an 
Edit icon next to a VLAN interface in the VLAN Summary screen. The following 
screen appears.

This icon is lit when the entry is active and dimmed when the entry is 
inactive.

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.
