Retry histogram
Refer to the Retry Histrogram screen for an overview of the retries transmitted by an access point
radio and whether those retries contained any data packets. Use this information in combination
with the error fields within a Radio Stats screen to assess overall radio performance.
To display a Retry Histogram screen for an access point radio:
1. Select Status and Statistics -> Radio Stats -> Radio1(802.11b/g/n) Stats -> Retry Histogram
from the Brocade Mobility 7131N-FGR Access Point menu tree.
A Radio Histogram screen is available for each access point radio (regardless of single or
dual-radio model).
The table’s first column shows 0 under Retries. The value under the Packets column directly to
the right shows the number of packets transmitted by this access point radio that required 0
retries (delivered on the first attempt). As you go down the table you can see the number of
packets requiring 1 retry, 2 retries etc. Use this information to assess whether an abundance
of retries warrants reconfiguring the access point radio to achieve better performance.
2. Click Apply to save any changes to the Radio Histogram screen. Navigating away from the
screen without clicking Apply results in changes to the screens being lost.
3. Click Undo Changes (if necessary) to undo any changes made to the screen. Undo Changes
reverts the settings to the last saved configuration.
4. Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout
before the applet is closed.
