Configuring QoS Queues
Configuring Quality of Service ( QoS ) on the AT-WA7400 Wireless Access
Point consists of setting parameters on existing queues for different types
of wireless traffic, and effectively specifying minimum and maximum wait
times (via Contention Windows) for transmission. The settings described
here apply to data transmission behavior on the access point only, not to
that of the client stations.
Note
For the guest interface, QoS queue settings apply to the access
point load as a whole (both
BSS es together).
On a two-radio access point these settings apply to both radios but
the traffic for each radio is queued independently. (The exception to
this is guest traffic as noted below.)
Internal and guest network traffic is always queued together within
each radio. This is the case on both one-radio and two-radio access
points.
QoS on the access point leverages existing information in the IP packet
header related to Type of Service ( ToS ). The access point examines the
ToS field in the headers of all packets that pass through the access point.
Based on the value in a packet’s ToS field, the access point prioritizes the
packet for transmission by assigning it to one of the queues. A different
type of data is associated with each queue. You can configure parameters
that determine how each queue is treated when it is sent by the access
point.
To configure QoS, perform the following procedure:
1. From the main menu, select Advanced > Quality of Service.
