Wi-Fi Array
The Command Line Interface 367
Configuring Radio Assurance Mode (Loopback Tests)
The Array uses the built-in monitor radio, IAP abg(n)2, 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 406.
The following actions may be configured:
z
alert-only—the Array will issue an alert in the Syslog.
z
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.
z
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.
z
off—Disable IAP loopback tests (no self-monitoring occurs). Radio
Assurance mode is off by default.
This is a global IAPs setting—abg(n)2 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.
