Configuration Backups

Access Point configurations can be saved as data files and later used to restore the

access point configuration. The Backup Configuration screen lets you save access

point settings in an external file. (You must have a TFTP server set up on which to

store the backup file. This is the server specified on the TFTP setup page.

When you back up a configuration, you must supply the name of the file that the

configuration is saved to. This file will be written to the upload/download directory

of the TFTP server. If you need to change the TFTP configuration, click the Change

button to open the TFTP Setup screen.

Use the Restore Configuration screen to restore settings from a previously saved

backup file to the current access point. If you select All Configuration Settings, the

saved configuration is restored completely.

If you select Only Template Settings, only general configuration parameters such

as WLAN service area, data transmission settings, security settings, RADIUS server

settings, and management setup information are restored. Template settings

would be used in common by several access points in a network and provide an

easy way to reconfigure all access points in a network, if required. Template

parameters do not affect nor overwrite settings unique to individual access points,

such as device name, location, IP addresses, and administration passwords.

Statistics

The statistics screens display various categories of operational and performance

statistics associated with the access point. The values do not update dynamically,

but you can update them at any time by refreshing the display.

If you click on the Start Refresh button, the refresh cycle begins and the values on

the screen are updated according to a predefine polling rate.

■

RF Statistics. Displays performance data for the radio transmissions to and

from the access point. The statistics related to transmissions from the access

point are listed in the Transmitted table on the left. Statistics related to radio

signals received by the access point are listed in the Received table on the right.

■

Ethernet Statistics. Displays performance data for the wired Ethernet traffic

to and from the access point. The statistics related to wired transmissions from

the access point are listed in the Transmitted table on the left. Statistics related

to Ethernet traffic received by the access point are listed in the Received table

on the right.

■

Interface Statistics. Displays the interface statistics for the access point. The

top table displays the interface counts, showing the cumulative packets or

frames sent and received and the bytes sent and received over the Ethernet and

wireless interfaces. The bottom table displays the rates per second for each of

these parameters.

■

Channel Retry Statistics. Provides statistics for each of the radio channels

supported by the access point. For each channel, the table indicates the

number of frames sent and received, and the number of retries that have

occurred for that channel.

■

Forwarding Counts. Displays the cumulative number of packets forwarded

between the two types of interfaces. The rows represent the source, and the

columns represent the destination of the forward.
