contain a matching Service Set Identifier (SSID) and authentication type. The phone associates with the
access point with the highest RSSI that matches with the network profile.
For more information, see Cisco Unified Wireless AP Interactions, on page 82 .
3 (For a Cisco DX650 in a wireless LAN only) Authenticate with the access point. The Cisco DX650 begins
the authentication process. The following table describes the authentication process:
Description Key Management Options Authentication Type
Any device can authenticate to the access point.
For added security, static WEP encryption might
optionally be used. None Open
The phone encrypts the challenge text by using
the WEP key and the access point must verify the
WEP key that was used to encrypt the challenge
text before network access is available. None Shared Key
The RADIUS server authenticates the username
and password before network access is available.
For more information about name and password
authentication, see
Wireless LAN Setup, on page
95 .
None LEAP or EAP-FAST
The phone searches for an access point with one
of the key management options enabled. The
username and password are authenticated by the
RADIUS server before network access is
available. WPA, WPA2, or CCKM Auto (AKM)
The phone looks for an access point that has one
of the key management options enabled.
Authentication uses the configured
WPA-Pre-shared key or WPA2-Pre-shared key WPA-Pre-shared key,
WPA2-Pre-shared key Auto (AKM)
For more information, see Authentication Methods, on page 86 .
4 Load the stored phone image. The Cisco DX650 has nonvolatile flash memory in which the phone stores
firmware images and user-defined preferences. At startup, the phone runs a bootstrap loader that loads a
phone firmware image that is stored in flash memory. Using this image, the phone initializes the software
and hardware.
5 Configure the VLAN. If the Cisco DX650 is connected to a Cisco Catalyst switch, the switch next informs
the phone of the voice VLAN that is defined on the switch. The phone needs the VLAN membership
information before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an
IP address.
For more information, see Ethernet Settings Menu, on page 105 .
6 Obtain an IP address. If the Cisco DX650 is using DHCP to obtain an IP address, the phone queries the
DHCP server to obtain one. If you are not using DHCP in your network, you must assign static IP addresses
to each phone locally.
