Type Field Description
Configuration Assigned Entitlements Status The system must be licensed to operate. A best
practice is to start the license renewal process at
least 90 days before the license expiration date to
avoid interruption of functionality.
The following are the available status warnings:
• Green status — All assigned entitlements
expire in more than 90 days.
• Yellow status warning — Some assigned
entitlements expire in less than 90 days.
• Red status warning — Some assigned
entitlements expire in less than 30 days.
To view the list of entitlements, go to
Administration > License > Entitlements.
For more information, refer to Subscription
License on page 396.
Configuration Scheduled Configuration Backup It is a best practice to schedule a configuration
backup. Automatically back up the configuration
to a separate media or host. You can restore your
configuration from a backup file in the event of a
system failure. See Configure a Backup Schedule
on page 358.
Configuration TKIP TKIP encryption is considered to be a less secure
means of communication. An industry best
practice is to use a more secure option for
network privacy. Disable the TKIP option within
the WPA2 privacy settings. See Privacy Settings
for WPA2 with PSK on page 226. A green check
mark indicates that TKIP encryption is not used. A
yellow warning condition indicates that TKIP
encryption is enabled on a WLAN.
Configuration APs adopted but not assigned to
a site
APs must be part of a device group and assigned
to a site. See Sites Overview on page 19.
Configuration AP has configuration overrides Indicates that there are APs in your network with
configured override settings. For a consistent
configuration, a best practice is to configure the
APs through the configuration Profile. Overrides
are available for unique configuration. However,
variances from the configuration Profile can result
in APs not receiving general policy changes.
Consider configuration Overrides carefully. To
determine which APs are configured with
overrides, from the AP List, display the Overrides
column. See Access Points List on page 61.
