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 Mobility 7131 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.
