Wireless Array
438 The Command Line Interface
Configuring Radio Assurance Mode (Loopback Tests)
The Array uses its built-in monitor radio to monitor other radios in the Array.
Tests include sending probes on all channels and checking for a response, and
checking whether beacons are received from the other radio. If a problem is
detected, corrective actions are taken to recover. Loopback mode operation is
described in detail in “Array Monitor and Radio Assurance Capabilities” on
page 460.
The following actions may be configured:
 alert-only — the Array will issue an alert in the Syslog.
 repair-without-reboot — the Array will issue an alert and reset radios at
the Physical Layer (Layer 1) and possibly at the MAC layer. The reset
should not be noticed by users, and they will not need to reassociate.
 reboot-allowed — the Array will issue an alert, reset the radios, and
schedule the Array to reboot at midnight (per local Array time) if
necessary. All stations will need to reassociate to the Array.
 off — Disable IAP loopback tests (no self-monitoring occurs). Radio
Assurance mode is off by default.
This is a global IAPs setting — the monitor radio will monitor all other radios
according to the settings above, and it cannot be set up to monitor particular
radios. Radio assurance mode requires Intrusion Detection to be set to Standard.
The following example shows you how to configure a loopback test.
