User Manual
Layer 2
The Egress Layer 2 page allows you to map the CoS of an outgoing packet to user priority
bits, which is honored by the VLAN network. Again, this feature is only configurable on
the WAN interfaces as VLAN is only supported on the WAN side in the current release.
Layer 2
Field
Description
Interface
Select the WAN interface to configure the QoS for outgoing packets; LAN interface
cannot be selected as VLAN is currently supported on the WAN side only.
Unclassified
Packet
Some locally generated packets might not have been classified and thus do not have
a CoS value, 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.
User Priority
The selections are 0, 1, 2, 3, 4, 5, 6, and 7.
