Priority on VLANs (802.1p)
The radios can prioritize traffic based on the eight priorities described in the IEEE 802.1p specification. When the
high-priority channel is enabled on an SM, regardless of whether VLAN is enabled on the AP for the sector,
packets received with a priority of 4 through 7 in the 802.1p field are forwarded onto the high-priority channel.
Operators may configure priority precedence as 802.1p Then Diffserv (Default) or Diffserv Then 802.1p. Since
these priority precedence configurations are independent between the AP and SM, this setting must be configured
on both the AP and the SM to ensure that the precedence is adhered to by both sides of the link.
