Wireless Array
Configuring the Wireless Array 319
automatically, based on changes in the environment. This is the
recommended method for channel allocation (see “RF Spectrum
Management” on page 318). The following options may be selected for
auto configuration:
Negotiate: negotiate air-time with other Arrays before performing a
full scan. Negotiating is slower, but if multiple Arrays are configuring
channels at the same time the Negotiate option ensures that multiple
Arrays don't select the same channels. Turning off the Negotiate
option allows the Auto Configure button to manually perform auto
channel without waiting, and may be used when you know that no
other nearby Arrays are configuring their channels.
Full Scan: perform a full traffic scan on all channels on all IAPs to
determine the best channel allocation.
Non-Radar: give preference to channels without radar-detect. See
table in “Procedure for Configuring Global 802.11an IAP Settings” on
page 293.
Include WDS: automatically assign 5GHz to WDS client links.
Click Factory Defaults if you wish to instruct the Array to return all IAPs
to their factory preset channels. As of release 6.3, Arrays no longer all use
the same factory preset values for channel assignments. Instead, if the
Array has been deployed for a while and already has data from the
spectrum analyzer and Xirrus Roaming Protocol about channel usage on
neighboring arrays, it performs a quick auto channel using that
information (without doing a full RF scan) to make an intelligent choice
of channel assignments. If the Array has been rebooted and has no saved
configuration or is just being deployed for the first time, it has no prior
data about its RF environment. In this case, it will pick a set of compatible
channel assignments at random.
On the XR-1000 Series Arrays, the Factory Defaults button will not
restore iap1 to monitor mode. You will need to restore this setting manually.
Also, you may need to set RF Monitor Mode to Timeshare Mode again -
see “RF Monitor” on page 314.
