Configuring Basic Network Parameters
This section describes how to configure basic network parameters for the IP phone.

DHCP
DHCP (Dynamic Host Configuration Protocol) is a network protocol used to dynamically
allocate network parameters to network hosts. The automatic allocation of network
parameters to hosts eases the administrative burden of maintaining an IP network. IP
phones comply with the DHCP specifications documented in RFC 2131. If using DHCP, IP
phones connected to the network become operational without having to be manually
assigned IP addresses and additional network parameters. DHCP is enabled on IP
phones by default.
DHCP Option
DHCP provides a framework for passing information to TCP/IP network devices. Network
This section mainly introduces IPv4 network parameters. IP phones also support IPv6. For
more information on IPv6, refer to IPv6 Support on page 191.
