4.3.7.2 Configure 802.1p Priority

The IEEE 802.1p extension of IEEE 802.1Q prioritizes traffic at the data-link/MAC layer

through a 3-bit header field that was never articulated in the original VLAN standard.

IEEE only suggests 802.1p definitions; it does not mandate them.

Figure 21 shows that 802.1p priority is applied individually to ports — and just above the

dashed line a link (Map 802.1p Priority) exists to the screen (Figure 22) where 4 priority

queues allow the 8 tags to be mapped in various schemes. These two sample screens

are for an 8-port switch. More ports would be displayed for a 16- or 24-port switch.
