Configuring the Wi-Fi Array 225
6. Management Modes
a. Network Assurance: Click the On button to enable this mode.
Network assurance checks network connectivity to each server that
you configure, such as the NTP server, RADIUS servers, SNMP trap
hosts, etc. By proactively identifying network resources that are
unavailable, the network manager can be alerted of problems
potentially before end-users notice an issue. The distributed
intelligence of Arrays provides this monitoring at multiple points
across the network, adding to the ability to isolate the problem and
expedite the resolution
Connectivity is checked when you configure a server. If a newly
configured server is unreachable, you will be notified directly and a
Syslog entry is created. Also, the Array cycles through all configured
servers on an ongoing basis, checking one per second, so that each
server is checked approximately every four or five minutes. Servers
are checked regardless of whether they are configured as IP addresses
or host names.
If a server becomes unreachable, a Syslog message is generated.
When the server again becomes reachable, another Syslog message is
generated.
To view the status of all configured servers checked by this feature,
please see “Network Assurance” on page 138.
b. PCI Audit Mode: Click the On button to enable this mode. In PCI
Audit Mode, the Array checks whether its configuration satisfies PCI
DSS wireless requirements. This mode does not change any other
settings, but will inform you of any violations that exist. Furthermore,
the Array will monitor changes that you make to its configuration in
CLI or the WMI. PCI Mode will warn you (and issue a Syslog
message) if the change violates PCI DSS requirements. A warning is
issued when a non-compliant change is first applied to the Array, and
also if you attempt to save a configuration that is non-compliant. Use
this command in conjunction with “The Xirrus Array PCI
Compliance Configuration” on page 457 to ensure that you are using
