RF Resilience
2. Radio Assurance Mode:
When this mode is enabled, the monitor radio
performs loopback tests on the Array. This mode requires RF Monitor
Mode to be enabled (Step 1) to enable self-monitoring functions. It also
requires a radio to be set to monitoring mode (see “Enabling Monitoring
on the Array” on page 488).
Operation of Radio Assurance mode is described in detail in “Array
Monitor and Radio Assurance Capabilities” on page 488.
The Radio Assurance mode scans and sends out probe requests on each
channel, in turn. It listens for all probe responses and beacons. These tests
are performed continuously (24/7). If no beacons or probe responses are
observed from a radio for a predetermined period, Radio Assurance
mode will take action according to the preference that you have specified:
• Failure alerts only — The Array will issue alerts in the Syslog, but
will not initiate repairs or reboots.
• Failure alerts & repairs, but no reboots — The Array will issue alerts
and perform resets of one or all of the radios if needed.
• Failure alerts & repairs & reboots if needed — The Array will issue
alerts, perform resets, and schedule reboots if needed.
• Disabled — Disable IAP radio assurance tests (no self-monitoring
occurs). Loopback tests are disabled by default.
3. Enable Standby Mode: Choose Yes to enable this Array to function as a
backup unit for the target Array, or choose No to disable this feature. See
“About Standby Mode” on page 321.
4. Standby Target Address: If you enabled the Standby Mode, enter the
MAC address of the target Array (i.e., the address of the primary Array
that is being monitored and backed up by this Array). To find this MAC
address, open the Array Info window on the target Array, and use the
Gigabit1 MAC Address.
