Networking Protocols
The IP Conference Station supports several industry-standard and Cisco
networking protocols required for voice communication.
Table 1-1
lists the
supported networking protocols and a brief overview of each.

Purpose
Usage Notes
Cisco Discovery Protocol (CDP) CDP is a device-discovery
protocol that runs on all
Cisco-manufactured equipment.
Using CDP, a device can
advertise its existence to other
devices and receive information
about other devices in the
network.
The IP Conference Station uses
CDP to communicate
configuration information to the
Cisco Catalyst switch. With
CDP, each device sends periodic
messages to a multicast address
and in turn listens to the periodic
messages sent by other devices.
This allows devices on the
network to discover one another
and learn information such as
protocols used, protocol
addresses, and so on.
Dynamic Host Configuration
Protocol (DHCP)
DHCP dynamically allocates and
assigns an IP address to network
devices.
DHCP enables you to connect
the IP phone into the network
and become operational without
manually assigning an IP address
and configuring additional
required network parameters.
DHCP is enabled by default. If
disabled, you must manually
configure the IP address, subnet
mask, gateway, and TFTP server
on each station.
