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 is presented, indicating that CDP should
be disabled on the switch port only if the phone is connected
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 TFTP servers
• Eliminates the need to manually control firmware upgrades
• Reduces phone downtime during upgrades when large numbers of
devices are reset simultaneously
Peer Firmware Sharing may also aid in firmware upgrades in
branch/remote office deployment scenarios over bandwidth-limited
WA N l i n k s .
When enabled, it allows the phone to discover like 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.
The individual files making up the firmware image are retrieved from
the TFTP server by only the root phone in the hierarchy, and are then
rapidly transferred down the transfer hierarchy to the other phones on
the subnet using TCP connections.
This menu option indicates whether the phone supports Peer Firmware
Sharing. Settings include:
• Enabled
• Disabled—default
Use Cisco Unified
Communications Manager
Administration, and choose
Device > Phone > Phone
Configuration.
Log Server Indicates the IP address and port of the remote logging machine to
which the phone sends log messages. These log messages help in
debugging the peer to peer image distribution feature.
Note The remote logging setting does not affect the sharing log
messages sent to the phone log.
