Option Description
Peer Firmware Sharing The Peer Firmware Sharing feature provides these
advantages in high speed campus LAN settings:
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:
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
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. Settings include:
