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.
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
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.
The remote logging setting does
Note
not affect the sharing log
messages that are sent to the
phone log.
