Usage NotesPurposeNetwork Protocol
The Cisco Desktop Collaboration
Experience DX650 uses CDP to
communicate information such as
auxiliary VLAN ID, per-port
power management details, and
Quality of Service (QoS)
configuration information with the
Cisco Catalyst switch.
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.
Cisco Discovery Protocol (CDP)
CPPDP is used by the Peer
Firmware Sharing feature.
CPPDP is a Cisco proprietary protocol that is used to form a
peer-to-peer hierarchy of devices. This hierarchy is used to
distribute firmware files from peer devices to their
neighboring devices.
Cisco Peer-to-Peer Distribution
Protocol (CPPDP)
DHCP is enabled by default. If it
is disabled, you must manually
configure the IP address, subnet
mask, gateway, and a TFTP server
on each phone locally.
Cisco recommends that you use
DHCP custom option 150. With
this method, you configure the
TFTP server IP address as the
option value. For additional
supported DHCP configurations,
see the “Dynamic Host
Configuration Protocol” chapter
and the “Cisco TFTP” chapter in
the Cisco Unified Communications
Manager System Guide.
If you cannot use option
150, you may try using
DHCP option 66.
Note
DHCP dynamically allocates and assigns an IP address to
network devices.
DHCP enables you to connect a Cisco Desktop Collaboration
Experience DX600 series device into the network and the
phone to become operational without the need to manually
assign an IP address or to configure additional network
parameters.
Dynamic Host Configuration
Protocol (DHCP)
Cisco Desktop Collaboration
Experience DX600 series phones
use HTTP for XML services and
for troubleshooting purposes.
HTTP is the standard way of transferring information and
moving documents across the Internet and the web.
Hypertext Transfer Protocol
(HTTP)
Web applications with both HTTP
and HTTPS support have two
URLs configured. Cisco Desktop
Collaboration Experience DX600
series phones that support HTTPS
choose the HTTPS URL.
Hypertext Transfer Protocol Secure (HTTPS) is a combination
of the Hypertext Transfer Protocol with the SSL/TLS protocol
to provide encryption and secure identification of servers.
