You can restrict the upload and download traffic on the SSID to a specific limit. Select Restrict upload traffic on this

SSID to and enter a value to restrict the upload traffic for the SSID.

Select Restrict download traffic on this SSID to and enter a value to restrict the download traffic for the SSID.

If you configure the radio in 11N mode, WMM (Wi-Fi multimedia) will always be enabled, irrespective of whether or

not you select the WMM check box, in the SSID profile. The reason for this behavior is that WMM is mandatory in

11N mode.

In 11N mode, if the WMM check box is not selected,the system uses the default QoS parameters. The system uses the

user-configured QoS settings if the WMM check box is selected.

Select the WMM check box and define your own QoS settings for Wi-Fi multimedia on the SSID profile.

Specify voice, video, best effort or background as the SSID Priority depending on your requirement.

Select Priority Type as Fixed if all traffic of this SSID has to be transmitted at the selected priority irrespective of the

priority indicated in the 802.1p or IP header.

Select Priority Type as Ceiling if traffic of this SSID can be transmitted at priorities equal to or lower than the

selected priority.

Select the Downstream mapping option if Priority Type is selected as Ceiling. The priority is extracted from the

selected field (802.1p, DSCP or TOS) and mapped to the wireless access category for the downstream traffic subject to

a maximum of the selected SSID Priority. For the downstream mappings, the mapping depends on the first 3 bits

(Class selector) of the DSCP value, TOS value or 802.1p access category. The only exception will be DSCP value 46

which will be mapped to WMM access category 'Voice'.

Select the Upstream marking option as per the requirement. The incoming wireless access category is mapped to a

priority subject to a maximum of the selected SSID priority and set in the 802.1p header and the IP header as selected.

Refer to the following table for the priority, 802.11e access category and the corresponding 802.1p access category and

DSCP value, used for upstream marking. If 802.1p marking is enabled, the 802.11e access category maps to the

corresponding 802.1p access category. If DSCP/TOS marking is enabled, the 802.11e access category maps to the

corresponding DSCP value.
