Binary Floor Control Protocol (BFCP)
|
BFCP allows users to share a presentation within an ongoing video conversation.
|
BFCP is automatically enabled.
|
Bluetooth
|
Bluetooth
is a wireless personal area network (WPAN) protocol that specifies how devices
communicate over short distances.
|
The
devices support Bluetooth 3.0.
The
devices support Hands-Free Profile (HFP), Advanced Audio Distribution (A2DP)
Profile, Human Interface Device Profile (HID), Object Push Profile (OPP), and
Phone Book Access Profile (PBAP).
|
Bootstrap
Protocol (BootP)
|
BootP
enables a network device to discover certain startup information, such as the
IP address.

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 device
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.
|
Cisco
Peer-to-Peer Distribution Protocol (CPPDP)
|
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.
|
The Peer Firmware Sharing feature uses CPPDP.
|
Dynamic
Host Configuration Protocol (DHCP)
|
DHCP
dynamically allocates and assigns an IP address to network devices.
DHCP
enables you to connect a device into the network and for that device to become
operational without the need to manually assign an IP address or to configure
additional network parameters.
|
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 device 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.
Note
|
If you
cannot use option 150, you may try using DHCP option 66.
|
|
Hypertext
Transfer Protocol (HTTP)
|
HTTP is
the standard way of transferring information and moving documents across the
Internet and the web.
|
Devices
use HTTP for XML services and for troubleshooting purposes.
|
Hypertext
Transfer Protocol Secure (HTTPS)
|
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.
|
Web
applications with both HTTP and HTTPS support have two URLs configured. Devices
that support HTTPS choose the HTTPS URL.
|
IEEE
802.1X
|
The IEEE
802.1X standard defines a client-server-based access control and authentication
protocol that restricts unauthorized clients from connecting to a LAN through
publicly accessible ports.
Until the
client is authenticated, 802.1X access control allows only Extensible
Authentication Protocol over LAN (EAPOL) traffic through the port to which the
client is connected. After authentication succeeds, normal traffic can
pass through the port.
|
Devices
implement the IEEE 802.1X standard by providing support for the following
authentication methods: EAP-FAST and EAP-TLS.
When
802.1X authentication is enabled on the device, you should disable the PC port
and voice VLAN.
|
IEEE
802.11a/b/g/n
|
The IEEE
802.11 standard specifies how devices communication over a wireless local area
network (WLAN).
802.11a
operates at the 5 GHz band, and 802.11b and 802.11g operate at the 2.4 GHz band.
802.11.n
operates in either 2.4 GHz or 5Ghz band.
|
The 802.11
interface is a deployment option for cases when Ethernet cabling is unavailable
or undesirable.
|
Internet
Protocol (IP)
|
IP is a
messaging protocol that addresses and sends packets across the network.
|
To
communicate using IP, network devices must have an assigned IP address, domain
name, gateway, and netmask.
IP
addresses, subnets, and gateway identifications are automatically assigned if
you are using the device with Dynamic Host Configuration Protocol (DHCP). If
you are not using DHCP, you must manually assign these properties to each device
locally.
The device supports IPv6 addresses. For
more information, see the
Features and Services Guide for Cisco Unified Communications Manager, “Internet Protocol Version 6
(IPv6)” chapter.
|
Link
Layer Discovery Protocol (LLDP)
|
LLDP is
a standardized network discovery protocol (similar to CDP) that is supported on
some Cisco and third-party devices.
|
The
device supports LLDP on the PC port.
|
Link
Layer Discovery Protocol - Media Endpoint Devices (LLDP-MED)
|
LLDP-MED
is an extension of the LLDP standard for voice products.
|
The
device supports LLDP-MED on the SW port to communicate information such as:
- Voice VLAN configuration
- Device discovery
- Power management
- Inventory management
For more
information about LLDP-MED support, see the LLDP-MED and Cisco Discovery
Protocol white paper:
http://www.cisco.com/en/US/tech/tk652/tk701/technologies_white_paper0900aecd804cd46d.shtml
|
Real-Time Transport Protocol (RTP)
|
RTP is a
standard protocol for transporting real-time data, such as interactive voice
and video, over data networks.
|
The
device uses the RTP protocol to send and receive real-time voice traffic from
other phones and gateways.
|
Real-Time Control Protocol (RTCP)
|
RTCP
works in conjunction with RTP to provide QoS data (such as jitter, latency, and
round-trip delay) on RTP streams.
RTCP is
also used to synchronize the audio and video stream in order to provide a
better video experience.
|
RTCP for
audio calls is disabled by default. RTCP for video calls (including both audio
streams and video streams in the video call) is enabled by default. You can
enable or disable RTCP on individual devices from Cisco Unified
Communications Manager Administration.
|
Session
Description Protocol (SDP)
|
SDP is
the portion of the SIP protocol that determines which parameters are available
during a connection between two endpoints. Conferences are established by using
only the SDP capabilities that all endpoints in the conference support.
|
SDP
capabilities, such as codec types, DTMF detection, and comfort noise, are
normally configured on a global basis by
Cisco Unified Communications Manager or Media Gateway in operation.
Some SIP endpoints may allow configuration of these parameters on the endpoint
itself.
|
Session
Initiation Protocol (SIP)
|
SIP is
the Internet Engineering Task Force (IETF) standard for multimedia conferencing
over IP. SIP is an ASCII-based application-layer control protocol (defined in
RFC 3261) that can be used to establish, maintain, and terminate calls between
two or more endpoints.
|
Like
other VoIP protocols, SIP addresses the functions of signaling and session
management within a packet telephony network. Signaling allows transportation
of call information across network boundaries. Session management provides the
ability to control the attributes of an end-to-end call.
|
Telepresence Interoperability Protocol
(TIP)/Multiplex (MUX)
|
TIP/MUX is an IP protocol that is used to
negotiate audio and video media options between endpoints prior to reception or
transmission of media.
|
TIP/MUX is invoked for multiparticipant
conferences and enables content sharing.
|
Transmission Control Protocol (TCP)
|
TCP is a
connection-oriented transport protocol.
|
The
device uses TCP to connect to
Cisco Unified Communications Manager and to access XML services.
|
Transport Layer Security (TLS)
|
TLS is a
standard protocol for securing and authenticating communications.
|
Upon
security implementation, the device uses the TLS protocol when securely
registering with
Cisco Unified Communications Manager.
|
Trivial
File Transfer Protocol (TFTP)
|
TFTP
allows you to transfer files over the network.
On the
device, TFTP enables you to obtain a configuration file specific to the device
type.
|
TFTP
requires a TFTP server in your network that the DHCP server can automatically
identify. If you want a device to use a TFTP server other than the one that the
DHCP server specifies, you must manually assign the IP address of the TFTP
server by using the Settings application on the device.
For more
information, see the
"Cisco TFTP" chapter in the Cisco Unified
Communications Manager System Guide.
|
User
Datagram Protocol (UDP)
|
UDP is a
connectionless messaging protocol for delivery of data packets.
|
UDP is
used only for RTP streams. SIP signaling on the devices does not support UDP.
