Device Configuration Menu Chapter 4 Configuring Settings on the Cisco Unified IP Phone Table 4-20 Network Configuration Menu Options (continued) Option Peer Firmware Sharing Log Server LLDP: PC Port LLDP-MED: SW Port Description To Change 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 From Cisco Unified Communications Manager Administration, choose Device > Phone > Phone Configuration. • 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-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 to peer image distribution feature. Note The remote logging setting does not affect the sharing log messages sent to the phone log. From Cisco Unified Communications Manager Administration, choose Device > Phone > Phone Configuration. 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 • Disabled From Cisco Unified Communications Manager Administration, choose Device > Phone > Phone Configuration. Enables and disables Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED) on the switch 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: From Cisco Unified Communications Manager Administration, choose Device > Phone > Phone Configuration. • Enabled-default • Disabled 4-34 Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.5 OL-23092-01
