PMP 450 Platform Family modules provide the VLAN frame filters that are described in
Table 80

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 a 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 SM to ensure that the precedence is adhered to by both sides of
the link.
