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 WAN links.
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
From Cisco Unified Communications
Manager Administration, 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 Firmware
Sharing feature.
Note The remote logging setting does not affect the
sharing log messages sent to the phone log.
Note If 0.0.0.0 is displayed, no logging will occur.
From Cisco Unified Communications
Manager Administration, choose
Device
> Phone > Phone
Configuration.
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, which
should match the protocol supported by the switch.
Settings include:
• Enabled—default
• Disabled
From Cisco Unified Communications
Manager Administration, choose
