Description
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
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.
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
