Ingress Layer 3 Configuration
The Layer 3 page allows you to map ToS bits of incoming packets from the IP network to CoS for
each WAN/LAN interface.
Interface
For both WAN and LAN interfaces, you can configure QoS for layer 3 (IP) data
traffic.
Class of Service This CoS field allows you to map incoming layer 3 WAN/LAN packets to one of
the following CoS (in the order of descending priority): CoS1, CoS2, CoS3,
CoS4, CoS5, and CoS6.
ToS The type of service field takes values from 0 to 255.
Default Non IP A static CoS can be assigned to all layer 3 incoming packets (per interface) that
do not have an IP header, such as PPP control packets and ARP packets. The
default is CoS1 (recommended).
To configure Ingress Layer 3 to CoS:
1. From Interface drop-down box, select LAN Group 1 to configure QoS on this interface.
2. Select CoS1 in Class of Service and enter 22 in Type of Service (ToS).
