Wi-Fi Array
246 Configuring the Wi-Fi Array
IEEE802.1p defines eight priority levels for wired networks. Each data packet
may be tagged with a priority level, i.e., a user priority tag. Since there are eight
possible user priority levels and the Array implements four wireless QoS levels,
user priorities are mapped to QoS as described below.
End-to-End QoS Handling
 Wired QoS - Ethernet Port:
Ingress: Incoming wired packets are assigned QoS priority based on their
SSID and 802.1p tag (if any), as shown in the table below. This table
follows the mapping recommended by IEEE802.11e.
