Load Server
|
Used to optimize installation time for phone
firmware upgrades and offload the WAN by storing images locally, which negates the
need to traverse the WAN link for each phone upgrade.
You can set the Load Server to another TFTP server
IP address or name (other than the TFTP Server 1 or TFTP Server 2) from which
the phone firmware can be retrieved for phone upgrades. When the Load Server
option is set, the phone contacts the designated server for the firmware
upgrade.
Note
|
The Load Server option allows you to specify an alternate
TFTP server for phone upgrades only. The phone continues to use TFTP Server 1
or TFTP Server 2 to obtain configuration files. The Load Server option does not
provide management of the process and of the files, such as file transfer,
compression, or deletion.

RTP Control Protocol
|
Indicates whether the phone supports the Real-Time
Control Protocol (RTCP). Settings include:
- Enabled
- Disabled (default)
If this feature is disabled, several call statistic
values display as 0. For more information, see the following sections:

|
CDP: PC Port
|
Indicates whether CDP is enabled on the PC port
(default is enabled).
Enable CDP on the PC port when Cisco VT
Advantage/Unified Video Advantage (CVTA) is connected to the PC port. CVTA does
not work without CDP interaction with the phone.
Note
|
When CDP is disabled in Cisco Unified Communications
Manager, a warning displays to indicate that disabling CDP on the PC port
prevents CVTA from working.
|
The current PC and switch port CDP values are shown
on the Settings menu.
|
From Cisco Unified Communications Manager
Administration, choose
.
|
CDP: SW Port
|
Indicates whether CDP is enabled on the switch port
(default is enabled).
- Enable CDP on the
switch port for VLAN assignment for the phone, power negotiation, QoS
management, and 802.1x security.
- Enable CDP on the
switch port when the phone is connected to a Cisco switch.
Note
|
When CDP is disabled in Cisco Unified Communications
Manager, a warning displays to indicate that CDP should be disabled on the
switch port only if the phone connects to a non-Cisco switch.
|
The current PC and switch port CDP values are shown
on the Settings menu.

Peer Firmware Sharing
|
The Peer Firmware Sharing feature provides these
advantages in high speed campus LAN settings:
- Limits congestion
on TFTP transfers to centralized remote TFTP servers.
- Eliminates the
need to manually control firmware upgrades.
- Reduces phone
downtime during upgrades when large numbers of devices are reset.
Peer Firmware Sharing may also aid in firmware
upgrades in branch/remote office deployment scenarios over bandwidth-limited
WAN links.
Enabling this setting allows the phone to discover similar
phones on the subnet that are requesting the files that make up the firmware
image, and to automatically assemble transfer hierarchies on a per-file basis.
Only the root phone in the hierarchy retrieves the individual files that make up the firmware image from the TFTP server,
and then the files are
transferred down the transfer hierarchy to the other phones on the subnet by using
TCP connections.
This menu option indicates whether the phone
supports peer firmware sharing. Settings include:
- Enabled (default)
- Disabled
|
From Cisco Unified Communications Manager
Administration, choose
.
|
Log Server
|
Indicates the IP address and port of the remote
logging machine to which the phone sends log messages. These log messages help
to debug the peer to peer image distribution feature.
Note
|
The remote logging setting does not affect the sharing log
messages that are sent to the phone log.

From Cisco Unified Communications Manager
Administration, choose
.
|
LLDP: PC Port
|
Enables and disables Link Layer Discovery Protocol
(LLDP) on the PC port. Use this setting to force the phone to use a specific
discovery protocol. Settings include:
- Enabled (default)
- Disabled
|
From Cisco Unified Communications Manager
Administration, choose
Device > Phone > Phone Configuration.
|
LLDP-MED: SW Port
|
Enables and disables Link Layer Discovery Protocol
Media Endpoint Discovery (LLDP-MED) on the switch port. Use this setting to
force the phone to use a specific discovery protocol, which should match the
protocol supported by the switch. Settings include:
- Enabled (default)
- Disabled
|
From Cisco Unified Communications Manager
Administration, choose
.
|
LLDP Asset ID
|
Identifies the asset ID assigned to the phone for
inventory management.
|
From Cisco Unified Communications Manager
Administration, choose

|
Wireless Headset Hookswitch Control
|
Enables users to receive notifications of incoming
calls and answer or end calls while they work in a wireless environment.
|
From Cisco Unified Communications Manager
Administration, choose
.
|
LLDP Power Priority
|
Advertises the phone power priority to the switch,
which enables the switch to appropriately provide power to the phone. Settings
include:
- Unknown (default)
- Low
- High
- Critical
|
From Cisco Unified Communications Manager
Administration, choose

|
IP Addressing Mode
|
Displays the IP addressing mode that is available on
the phone. IPv4 only, IPv6 only, or IPv4 and IPv6.
|
From Cisco Unified Communications Manager
Administration, choose
.
|
IP Preference Mode Control
|
Indicates the IP address version that the phone uses
during signaling with Cisco Unified Communications Manager when both IPv4 and
IPv6 are available on the phone.
The IP addressing mode preference is configured on
Cisco Unified Communications Manager Administration.
Displays one of the following options on the phone:
- IPv4: The
dual-stack phone prefers to establish a connection via an IPv4 address during a
signaling event.
- IPv6: The
dual-stack phone prefers to establish a connection via an IPv6 address during a
signaling event.
|
From Cisco Unified Communications Manager
Administration, choose
.
|
Auto IP Configuration
|
Displays whether the auto configurations is enabled
or disabled on the phone.
The Auto IP Configuration setting along with the
DHCPv6 setting determine how the IP phone obtains the IPv6 address and other
network settings. For more information on how these two settings affect the
network settings on the phone, see
DHCPv6 and Autoconfiguration.
Note
|
Use the
"Allow Auto Configuration for Phones" setting in Cisco
Unified Communications Manager Administration.

IPv6 Load Server
|
Used to optimize installation time for phone
firmware upgrades and offload the WAN by storing images locally, which negates the
need to traverse the WAN link for each phone upgrade.
You can set the Load Server to another TFTP server
IP address or name (other than the IPv6 TFTP Server 1 or IPv6 TFTP Server 2)
from which the phone firmware can be retrieved for phone upgrades. When the
Load Server option is set, the phone contacts the designated server for the
firmware upgrade.
Note
|

TFTP server for phone upgrades only. The phone continues to use IPv6 TFTP
Server 1 or IPv6 TFTP Server 2 to obtain configuration files. The Load Server
option does not provide management of the process and of the files, such as
file transfer, compression, or deletion.
