Configuring the Cisco Wireless IP Phone 8821 and 8821-EX

Wi-Fi Profile Configuration

To configure the Wi-Fi settings on the Cisco Wireless IP Phone 8821 and 8821-EX, either use the desktop charger or default
Wi-Fi profile to connect to a Cisco Unified Communications Manager, use the phone's admin webpage interface, or use the
local user interface and keypad.

Automatic Provisioning

For automatic provisioning of the Wi-Fi Profiles, the Cisco Wireless IP Phone 8821 and 8821-EX needs to be connected to a
network either while docked with a supported USB to Ethernet dongle connected in the back of the dock or using the default
Wi-Fi settings (SSID = cisco and Security Mode = None), which has connectivity to the Cisco Unified Communications
Manager.
The Voice VLAN feature is supported as of the 11.0(3) release, but was not in previous releases so the native VLAN was
utilized.
The VLAN of the switch port in which the USB to Ethernet dongle is connected to (Voice VLAN if enabled) must have
connectivity to the CUCM and that VLAN must offer DHCP option 150 pointing it to the CUCM.
Wired 802.1x authentication and DHCP snooping features are not supported when using the USB to Ethernet dongle, so need to
ensure the switchport is configured properly.
Use of a supported USB to Ethernet dongle is for initial provisioning purposes only and not to convert the Cisco Wireless IP
Phone 8821 or 8821-EX to a wired IP phone. Voice calls over Ethernet are not supported.
The following USB to Ethernet dongles are supported.

With connectivity to a Cisco Unified Communications Manager 10.0 or later, Wi-Fi profile configuration data can be
downloaded and applied to the Cisco Wireless IP Phone 8821 and 8821-EX.
Cisco Unified Communications Manager 11.0 or later is required if wanting to download and apply a Wi-Fi profile including
EAP-TLS authentication.
