vendor specific attributes. An administrator can set separate QoS rate limit configurations for data
transmitted from the access point (upstream) and data transmitted from a WLAN’s wireless clients back
to their associated access point radios (downstream). Altitude 4511 and Altitude 4521 access points do
not support rate limiting on an individual client basis.
Before defining rate limit thresholds for WLAN upstream and downstream traffic, Extreme Networks
recommends you define the normal number of ARP, broadcast, multicast and unknown unicast packets
that typically transmit and receive from each supported WMM access category. If thresholds are defined
too low, normal network traffic (required by end-user devices) is dropped, resulting in intermittent
outages and performance problems.
To configure a QoS rate limit configuration for a WLAN and connected clients:
1 Select Configuration > Wireless > WLAN QoS Policy to display existing QoS policies available to
WLANs.
2 Either select the Add button to define a new WLAN QoS policy, or select an existing WLAN QoS
policy and Edit to modify its existing configuration.
3 Select the Rate Limit tab.
