Description

 

 

Interface

Select the WAN interface to configure the QoS for outgoing packets; LAN interface cannot be

Some locally generated packets might not have been classified and thus do not have a CoS value,

Packet

such as PPP control packet and ARP packet. You can define the CoS for all unclassified outgoing

 

packets on layer 2 using this field, which will then pick up the user priority bits based on the

 

mapping rules you create. The selections are (in the order of descending priority): CoS1, CoS2,

 

CoS3, CoS4, CoS5, and CoS6. The default value is CoS1 (recommended).

 

 

Class of Service

The selections are (in the order of descending priority): CoS1, CoS2, CoS3, CoS4, CoS5, and

 

CoS6.
