IPv6 Fields
Before IPv6 setup options can be configured on your device, IPv6 must be enabled and configured in Cisco
Unified Communication Administration. The following device configuration fields apply to IPv6 configuration:
• IP Addressing Mode
• IP Addressing Mode Preference for Signalling
If IPv6 is enabled in the Unified cluster, the default setting for IP addressing mode is IPv4 and IPv6. In this
addressing mode, the phone acquires and uses one IPv4 address and one IPv6 address. It can use the IPv4 and
the IPv6 address as required for media. The phone uses either the IPv4 or IPv6 address for call control signaling.
For more details about IPv6 deployment, see the
Release
You set up IPv6 from one of the following menus:
• When Wi-Fi is disabled: Ethernet Setup > IPv6 setup
• When Wi-Fi is enabled: Wi-Fi Client Setup > IPv6 setup
Use the phone keypad to enter or edit an IPv6 address. To enter a colon, press the asterisk (*) on the keypad.
To enter hexadecimal digits a, b, and c, press 2 on the keypad, scroll to select the required digit, and press
Enter. To enter hexadecimal digits d, e, and f, press 3 on the keypad, scroll to select the required digit, and
press Enter.
The following table describes the IPv6 related information found in the IPv6 menu.
