Mapping 802.1p Priority
The IEEE 802.1p feature allows traffic prioritization at the MAC level. The switch can prioritize traffic
based on the 802.1p tag attached to the Layer 2 frame. Each port on the switch has multiple queues to
give preference to certain packets over others based on the
criteria you specify. When a packet is
queued for transmission in a port, the rate at which it is serviced depends on how the queue is
configured and possibly the amount of traffic present in the other queues of the port. If a delay is
necessary, packets get held in the queue until the scheduler authorizes the queue for transmission.
Use the 802.1p Priority Mapping page in the Class of Service folder to assign 802.1p priority values to
various traffic classes on one or more interfaces.

Table 241: 802.1p Priority Mapping
Field
Description
Interface
The interface associated with the rest of the data in the row. The Global entry represents the
common settings for all interfaces, unless specifically overridden individually.
Priority
The heading row lists each 802.1p priority value (0–7), and the data in the table shows which
traffic class is mapped to the priority value. Incoming frames containing the designated
802.1p priority value are mapped to the corresponding traffic class in the device.
