3. Select the prioritization protocol used by your wireless stations:
• 802.1p is a Layer 2 protocol that marks traffic in the VLAN tag for one of
eight priorities.
• DSCP is a Layer 3 protocol that marks traffic in the IP header for one of 64
priorities.
Wireless devices queue frames according to the priority marked by the selected
protocol. For example, if you select 802.1p, a wireless devices transmits a frame
with priority value of 5 in its VLAN tag, using the parameters for the Video AC.
A frame with a DSCP value in the IP header, but no 802.1p value, is transmitted
according to the Best Effort AC.
Refer to Table 4-8 on page 4-92 to review to which ACs various priority values
map. See “Customizing How QoS Marks Map to ACs” on page 4-106 to change
which values map to which ACs.
