Installing Cisco Unified IP Phones
6. If you are configuring the network settings on the
phone for an IPv6 network, you can set up an IP
address for the phone by either using DHCPv6 or
manually entering an IP address.
Using DHCPv6—To enable DHCPv6 and allow the
DHCPv6 server to automatically assign an IP address
to the Cisco Unified IP Phone and direct the phone to
a TFTP server, choose Settings > Network
Configuration> IPv6 Configuration and:
• To enable DHCPv6,set DHCPv6 Enabled to Yes.
DHCPv6 is enabled by default.
• To use an alternate TFTP server, set IPv6
Alternate TFTP Server to Yes, and enter the IP
address for IPv6 TFTP Server 1.
Note Consult with the network administrator if you
need to assign an alternative TFTP server
instead of using the TFTP server assigned by
DHCP.
Without DHCP—You must configure the IP address,
subnet mask, TFTP server, and default router locally
on the phone, choose Settings > Network
Configuration> IPv6 Configuration:
To disable DHCP and manually set an IP address:
a. To disable DHCPv6, set DHCPv6 Enabled to No.
b. Enter the static IP address for phone.
c. Enter the IPv6 prefix length.
d. Set IPv6 Alternate TFTP Server to Yes , and enter
IP address for IPv6 TFTP Server 1.
You must also enter the domain name where the phone
resides by Choosing Settings > Network
Configuration.
Note The Cisco Unified IP Phone supports having
both IPv4 and an IPv6 address concurrently.
You can configure Cisco Unified
Communications Manager to support IPv4
addresses only, IPv6 addresses only, or
support both IPv4/IPv6 addresses.
