260 Configuring the Wi-Fi Array
Procedure for Configuring Global IAP Settings
1. Country: If no country is set, you may choose from the pull-down list.
Once a country has been chosen, it may not be changed. You are
responsible for choosing the correct country and conforming to the
regulatory laws for wireless transmissions within your country. Please
contact Xirrus Customer Support if you need to change the operating
country after a country has already been set (see “Contact Information”
on page 419).
The channels that are available for assignment to an IAP will differ,
depending on the country of operation. If you set Country to United
States, then 24 channels are available to 802.11a(n) radios.
Until you have chosen a country, the channel set defaults to channels and
power levels that are legal worldwide—this set only includes the lower
eight 5 GHz channels.
2. IAP Status: Click on the Enable All IAPs button to enable all IAPs for
this Array, or click on the Disable All IAPs button to disable all IAPs.
3. Short Retry Limit: This attribute indicates the maximum number of
transmission attempts for a frame, the length of which is less than or
equal to the RTS Threshold, before a failure condition is indicated. The
default value is 7. Enter a new value (1 to 128) in the Short Retry Limit
field if you want to increase or decrease this attribute.
4. Long Retry Limit: This attribute indicates the maximum number of
transmission attempts for a frame, the length of which is greater than the
RTS Threshold, before a failure condition is indicated. The default value
is 4. Enter a new value (1 to 128) in the Long Retry Limit field if you want
to increase or decrease this attribute.
