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.
