DESCRIPTION

Quality of Service

 

 

QoS

Use this field to turn on QoS to improve your network performance.

 

You can give priority to traffic that the ZyXEL Device forwards out

 

through the WAN interface. Give high priority to voice and video to make

 

them run more smoothly. Similarly, give low priority to many large file

 

downloads so that they do not reduce the quality of other applications.

 

 

Summary

Click this to open a summary table showing the QoS settings. See

 

Section 14.2.1 on page 173 for more details.

 

 

Rule

 

 

 

Rule Index

Select the rule’s index number from the drop-down list box.

 

 

Active

Use this field to enable or disable the rule.

 

 

Application

Select an application from the drop-down list box. The Destination Port

 

Range and Protocol ID fields may change depending on the type of

 

applications you choose.

 

 

Physical Ports

Select Enet1 to apply the rule to the Ethernet port.

 

 

Destination

Type a destination MAC address here. QoS is then applied to traffic

MAC

containing this destination MAC address. Leave it blank to apply the rule

 

to all MAC addresses.

 

 

IP

Enter a destination IP address in dotted decimal notation. QoS is then

 

applied to traffic containing this destination IP address. A blank

 

destination IP address means any destination IP address.

 

 

Mask

Enter a destination subnet mask here.

 

 

Port Range

Either use the default value set by the application you choose, or enter

 

the port number to which the rule should be applied.

 

 

Source MAC

Type a source MAC address here. QoS is then applied to traffic containing

 

this source MAC address. Leave it blank to apply the rule to all MAC

 

addresses.

 

 

IP

Enter a source IP address in dotted decimal notation. QoS is then applied

 

to traffic containing this source IP address. A blank source IP address

 

means any source IP address.

 

 

Mask

Enter a source subnet mask here.

 

 

Port Range

Enter the port number to which the rule should be applied. 0 means any

 

source port number. See Appendix E on page 305 for some common

 

services and port numbers.

 

 

Protocol ID

Select an IP protocol type from the drop-down list box.

 

 

Vlan ID Range

Enter the source VLAN ID in this field.

 

 

IPP/DS Field

Select IPP/TOS to specify an IP precedence range and type of services.

 

Select DSCP to specify a DiffServ Code Point (DSCP) range.

 

 

IP Precedence

Enter a range from 0 to 7 for IP precedence. Zero is the lowest priority

Range

and seven is the highest.
