Chapter 1 An Overview of the Cisco Unified IP Phone
Overview of Configuring and Installing Cisco Unified IP Phones
5. 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 DHCP or manually entering an
IP address.
Using DHCP—To enable DHCP and allow the DHCP 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 CM to support IPv4 addresses
only, IPv6 addresses only, or support both IPv4/IPv6 addresses.
