Chapter 1 An Overview of the Cisco Unified IP Phones
Overview of Configuring and Installing Cisco Unified IP Phones
5. If you are configuring the network settings on the phone for an
IPv4 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> IPv4 Configuration and configure
the following:
• To enable DHCP, set DHCP Enabled to Yes. DHCP is
enabled by default.
• To use an alternate TFTP server, set Alternate TFTP Server
to Yes, and enter the IP address for the TFTP Server.
Note Consult with the network administrator to determine
whether 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> IPv4
Configuration:
To disable DHCP and manually set an IP address:
a. To disable DHCP, set DHCP Enabled to No.
b. Enter the static IP address for phone.
c. Enter the subnet mask.
d. Enter the default router IP addresses.
e. Set Alternate TFTP Server to Yes, and enter the IP address
for TFTP Server 1.
You must also enter the domain name where the phone resides by
Choosing Settings > Network Configuration.
The Cisco Unified IP Phones support 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.
