Name

 

The text may consist of up to 20 letters, numerals and any printable

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 16.5.4 on page 267 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

Address

 

switch on the 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.

 

 

 

Tag Configuration

 

 

 

DSCP Value

 

Select Same to keep the DSCP fields in the packets.

 

 

Select Auto to map the DSCP value to 802.1 priority level

 

 

automatically.
