Traffic Groupings - Extreme Networks ExtremeWare XOS Guide Manual

The default QoS profiles cannot be deleted. Also by default, a QoS profile maps directly to a specific
hardware queue across all physical ports. The settings for the default QoS parameters on the
BlackDiamond 10K switch are summarized in

Traffic Groupings

After a QoS profile has been created or modified, you assign a traffic grouping to the profile. A traffic
grouping is a classification of traffic that has one or more attributes in common. Traffic is typically
grouped based on the needs of the applications discussed starting
Traffic groupings are separated into the following categories for discussion:
ACL-based information
●
Explicit packet class of service information, such as 802.1p or DiffServ (IP TOS)
●
Physical/Logical configuration (physical source port or VLAN association)
●
In the event that a given packet matches two or more grouping criteria, there is a predetermined
precedence for which traffic grouping applies. The supported traffic groupings, by precedence, are listed
in Table 33. In general, the more specific traffic grouping takes precedence. Those groupings listed at the
top of the table are evaluated first. By default, all traffic groupings are placed in the QoS profile QP1.
The groupings are listed in order of precedence (highest to lowest). The three types of traffic groupings
are described in detail on the following pages.
NOTE
On the Aspen 8810 switch, the precedence of IP ACL or MAC ACK depends on specifications in the ACL file itself.
Refer to Chapter 11 for more information on ACLs.
