Configuring IPv6 in Cisco Unified CM

Before you enable IPv6 in Cisco Unified CM Administration, you must configure IPv6 on each server in the cluster by using the following commands in the server operating system (OS) command line interface (CLI):

Enable IPv6 by using the set network ipv6 service enable command.

Set a static IPv6 address for your server by using the set network ipv6 static_address <addr> <mask> command. The DHCPv6 client is also supported, but it is not recommended.

To view the platform's IPv6 address settings, use the show network ipv6 settings command. Example output from this command is as follows:

IPv6   : enabled
DHCPv6 : disabled
       IPv6 addresses:
	Address:2001:db8:c18:1:21c:c4ff:feef:ca0        Mask:64
	Scope:Global    Duplicate:no

	Address:fe80::21c:c4ff:feef:ca0 Mask:64
	Scope:Link

Next, define the IPv6 address for each Unified CM server by using Cisco Unified CM Administration to select System > Server, and enter the IPv6 address in the field labeled IPv6 Name. (See Configuring Unified CM Server IPv6 Addresses.) The IPv6 address in this field enables Skinny Client Control Protocol (SCCP) phones to retrieve the IPv6 address of Unified CM from the configuration file downloaded from the TFTP server.

Configuring the Unified CM Server Hardware IPv6 Address Through Cisco Unified Operating System Administration

Instead of using the server command line interface as described above, you can use Cisco Unified Operating System Administration to set the Unified CM server IPv6 address. In Cisco Unified OS Administration, select Settings > IP > Ethernet IPv6, as illustrated in Figure A-1.

Configuring Unified CM Server IPv6 Addresses

After you have configured the server platform IPv6 address, define the IPv6 address for each Unified CM server by using Cisco Unified CM Administration. Select System > Server, and enter the IPv6 address in the IPv6 Name field (see Figure A-2). The IPv6 address in this field enables Skinny Client Control Protocol (SCCP) phones to retrieve the IPv6 address of this Unified CM from the configuration file downloaded from the TFTP server.
