For all 802.11ac settings, go to “Global Settings .11ac” on page 312.
Procedure for Manually Configuring IAPs
1. In the Enabled column, check the box for an IAP to enable it, or uncheck
the box if you want to disable the IAP.
2. In the Band column, select the wireless band for this IAP from the choices
available in the pull-down menu, either 2.4GHz or 5 GHz. Choosing the
5GHz band will automatically select an adjacent channel for bonding. If
the band displayed is auto, the Band is about to be changed based on a
new Channel selection that you made that requires the change.
One of the IAPs must be set to monitor mode if you wish to support
Spectrum Analyzer, Radio Assurance (loopback testing), and Intrusion
Detection features. Monitoring has a Timeshare mode option, which is
especially useful for small Arrays with two IAPs, such as the XR-500 and
XR-600 Series, allowing one IAP to be shared between monitoring the
airwaves for problems and providing services to stations. See RF Monitor
Mode in “Advanced RF Settings” on page 320 to set this option.
3. In the WiFi Mode column, select the IEEE 802.11 wireless mode (or
combination) that you want to allow on this IAP. The drop-down list will
only display the appropriate choices for the selected Band. For example,
the 5 GHz band allows you to select ac-only, anac, an, a-only, or n-only,
while 2.4GHz includes 802.11b and 802.11g choices. When you select a
WiFi Mode for an IAP, your selection in the Channel column will be
checked to ensure that it is a valid choice for that WiFi Mode.
By selecting appropriate WiFi Modes for the radios on your Arrays, you
can greatly improve wireless network performance. For example, if you
have 802.11n and 802.11ac stations using the same IAP, throughput on
that radio is reduced greatly for the 802.11ac stations. By supporting
For XR-520 Series Arrays only:
—iap1 may be set to either band or to monitor (also see the Timeshare
option in “RF Monitor” on page 321).
—iap2 is permanently set to 5 GHz.
