Wlan Settings - Cisco 8821 Manual

WLAN Settings

It is recommended to have a separate SSID for the Cisco Wireless IP Phone 8821 and 8821-EX.
However, if there is an existing SSID configured to support voice capable Cisco Wireless LAN endpoints already, then that
WLAN can be utilized instead.
The SSID to be used by the Cisco Wireless IP Phone 8821 and 8821-EX can be configured to only apply to a certain 802.11
radio type (e.g. 802.11a only).
It is recommended to have the Cisco Wireless IP Phone 8821 and 8821-EX operate on the 5 GHz band only due to have many
channels available and not as many interferers as the 2.4 GHz band has.
Ensure that the selected SSID is not utilized by any other wireless LANs as that could lead to failures when powering on or
during roaming; especially if a different security type is utilized.
To utilize 802.11r (FT) for fast secure roaming, check the box to enable Fast Transition.
Is recommended to uncheck Over the DS to utilize the Over the Air method instead of the Over the Distribution System
method.
Enable WPA2 policy with AES encryption then either FT 802.1x or FT PSK for authenticated key management type depending
on whether 802.1x or PSK is to be utilized.
