Each field is explained in the following table.

Table 53 Network > Interface > VLAN > Edit

LABEL	DESCRIPTION
VLAN Interface
Properties
Enable	Select this to enable this interface. Clear this to disable this interface.
Interface Name	This field is read-only if you are editing the interface. Enter the name of the
	VLAN interface. The format is vlanx, where x is 0 - 31. For example, vlan0,
	vlan8, and so on.
Port	Select the Ethernet interface on which the VLAN interface runs.
Virtual LAN Tag	Enter the VLAN ID. This 12-bit number uniquely identifies each VLAN. Allowed
	values are 1 - 4094. (0 and 4095 are reserved.)
Description	Enter a description of this interface. It is not used elsewhere. You can use
	alphanumeric and ()+/:=?!*#@$_%- characters, and it can be up to 60
	characters long.
IP Address
Assignment
Get	Select this if this interface is a DHCP client. In this case, the DHCP server
Automatically	configures the IP address, subnet mask, and gateway automatically.
	You should not select this if the interface is assigned to a VRRP group. See
	Chapter 33 on page 493.
Use Fixed IP	Select this if you want to specify the IP address, subnet mask, and gateway
Address	manually.
IP Address	This field is enabled if you select Use Fixed IP Address.
	Enter the IP address for this interface.
Subnet Mask	This field is enabled if you select Use Fixed IP Address.
	Enter the subnet mask of this interface in dot decimal notation. The subnet
	mask indicates what part of the IP address is the same for all computers in the
	network.
Gateway	This field is enabled if you select Use Fixed IP Address.
	Enter the IP address of the gateway. The ZyWALL sends packets to the
	gateway when it does not know how to route the packet to its destination. The
	gateway should be on the same network as the interface.
Metric	Enter the priority of the gateway (if any) on this interface. The ZyWALL decides
	which gateway to use based on this priority. The lower the number, the higher
	the priority. If two or more gateways have the same priority, the ZyWALL uses
	the one that was configured first.
Interface
Parameters
Upstream	Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
Bandwidth	send through the interface to the network. Allowed values are 0 - 1048576.
Downstream	This is reserved for future use.
Bandwidth	Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
	receive from the network through the interface. Allowed values are 0 - 1048576.
MTU	Maximum Transmission Unit. Type the maximum size of each data packet, in
	bytes, that can move through this interface. If a larger packet arrives, the
	ZyWALL divides it into smaller fragments. Allowed values are 576 - 1500.
	Usually, this value is 1500.
