Wireless Array
Configuring the Wireless Array 259
 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.
Wireless QoS - Radios:
 Each SSID can be assigned a separate QoS priority (i.e., traffic class) from
0 to 3, where 3 is highest priority and 2 is the default. See “SSID
Management” on page 262. If multiple SSIDs are used, packets from the
SSID with higher priority are transmitted first.
 The Array supports IEEE802.11e Wireless QoS for downstream traffic.
Higher priority packets wait a shorter time before gaining access to the
air and contend less with all other 802.11 devices on a channel.
 How QoS is set for a packet in case of conflicting values:
