Description
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 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 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. 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—default
• Disabled

remote logging machine to which the
