Peer Firmware Sharing

Peer Firmware Sharing (PFS) improves the upgrade process by allowing Cisco Unified IP Phones to pass
software upgrades between similar models in a network.
The feature provides the following 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 that
run over bandwidth-limited WAN links.
This feature is enabled by default. It has no user impact.
The feature is supported on the following phones (SCCP and SIP):
• Cisco Unified IP Phone 6921
• Cisco Unified IP Phone 6941
• Cisco Unified IP Phone 6945
• Cisco Unified IP Phone 6961
