Ipqos For Vdsl 2 And Adsl2+ To Vdsl2 Migration Examples - ZyXEL Communications MSC1024G Series User Manual

Changing the IEEE 802.1p to switch queue mapping may result in unexpected queuing
behavior. This is because even if you change the mapping between the IEEE 802.1p priorities
and the switch queues, the system still uses the same mapping between the switch queues and
the IPQoS profile queues. See
happen when you do not use the default IEEE 802.1p to switch queue mapping.

13.23.3 IPQoS for VDSL 2 and ADSL2+ to VDSL2 Migration Examples

These examples are compatible with both VDSL2 and ADSL2+. This makes them useful in
case the line needs to fall back to ADSL2+ or some subscribers still have ADSL2+ devices
and you want to migrate them to VDSL2 later.
13.23.3.1 VDSL Mode: 1 PVC with 8 Queues Example
This example configures a very simple IPQoS profile and applies it to a VDSL port. This
IPQoS profile is also compatible with ADSL2+. The IPQoS profile uses 8 traffic queues with
a single PVC. Each traffic queue uses the default priority level (the same as the queue ID).
This results in 8 queue priority levels and a 1:1 mapping from the 8 IEEE 801.1p priorities.

Here's how to configure port 1 to use these settings.
