Table
4-4. Current 802.1p Priority Mapping Table Fields
Field
Description
Global
Select the Global option to apply the same 802.1p priority mapping to all CoS
configurable interfaces.
Interface
The menu contains all CoS configurable interfaces. Select an individual interface
from the menu to override the global settings for 802.1p priority mapping on a per-
interface basis.
802.1p Priority
This row contains traffic class selectors for each of the eight 802.1p priorities to be
mapped. The priority goes from low (0) to high (3). For example, traffic with a priority
of 0 is for most data traffic and is sent using “best effort.” Traffic with a higher priority,
such as 3, might be time-sensitive traffic, such as voice or video.
The values in each drop down menu represent the traffic class. The traffic class is
the hardware queue for a port. Higher traffic class values indicate a higher queue
position. Before traffic in a lower queue is sent, it must wait for traffic in higher
queues to be sent.
