To manually configure mapping values, refer to “Assigning mapping values” on
page 341 .
Setting up filters and filter groups
Filters allow you to classify packets by various parameters. (For more information
on these parameters, refer to Chapter 4.) Filters are combined into filter groups.
Filter groups are then associated with an interface group.
You configure filter specifications. The QoS Advanced > Rules > IP Classification
page or the QoS Advanced > Rules > Layer 2 Classification page allows you to
enter matching conditions for an individual filter. You set up special conditions for
packet processing. In order for packets to be processed, a packet has to match all
the fields you specify.
Note: If you delete a role combination, you must remove all ports in the
Interface Group Assignment page first. A role combination cannot be
deleted if it is referenced by an installed meter.
Note:
Nortel Networks recommends that you use the default mapping
values to ensure end-to-end QoS connectivity across Nortel Network
products.
