Interface

Select from which interface traffic of this class should come.

 

 

Priority

Select a priority level (between 0 and 7) or select Auto to have the ZyXEL

 

Device map the matched traffic to a queue according to the internal QoS

 

mapping table. See Section 15.5.4 on page 238 for more information.

 

"0" is the lowest priority level and "7" is the highest.

 

 

Routing Policy

Select the next hop to which traffic of this class should be forwarded.

 

Select By Routing Table to have the ZyXEL Device use the routing table to find

 

a next hop and forward the matched packets automatically.

 

Select To WAN Index to route the matched packets through the specified PVC.

 

This option is available only when the WAN type is ADSL.

 

Select To Gateway Address to route the matched packets to the router or

 

switch you specified in the Gateway Address field.

 

 

WAN Index

Select a PVC index number.

 

 

Gateway

Enter the IP address of the gateway, which should be a router or switch on the

Address

same segment as the ZyXEL Device’s interface(s), that can forward the packet

 

to the destination.

 

 

Order

This shows the ordering number of this classifier. Select an existing number for

 

where you want to put this classifier and click Apply to move the classifier to the

 

number you selected. For example, if you select 2, the classifier you are moving

 

becomes number 2 and the previous classifier 2 gets pushed down one.
