Ssid / Wlan Settings - Cisco 7925G Series Deployment Manual

Note: If clients from other regions are present and will attempt to associate with the wireless LAN, then ensure that World
Mode (802.11d) is enabled.
When using 802.1x authentication, it is recommended to implement CCKM to offer fast secure roaming.

SSID / WLAN Settings

The SSID to be used by voice clients can be configured to only apply to a certain 802.11 radio type.
It is recommended to have the Cisco Unified Wireless IP Phone 7925G Series operate on the 5 GHz band due to have many
channels available and not as many interferers as the 2.4 GHz band has.
In order to utilize CCKM, enable WPA2 policy with AES encryption and 802.1x + CCKM for authenticated key management
type when the Cisco Unified Wireless IP Phone 7925G Series is running firmware version 1.3(4) or later in order to enable fast
secure roaming.
If the Cisco Unified Wireless IP Phone 7925G Series is running firmware version 1.3(3) or earlier, then enable WPA policy
with TKIP encryption and 802.1x + CCKM for authenticated key management type in order to enable fast secure roaming.
