Cisco Unified IP Phone Installation
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.
Step 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.
a) 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
Note
b) 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:
1 To disable DHCPv6, set DHCPv6 Enabled to No.
2 Enter the static IP address for phone.
3 Enter the IPv6 prefix length.
4 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
