How can I do peer firmware sharing on 78XX series phones in 8.6.2 or 10.5 CM

How can I do peer firmware sharing on 78XX series phones in 8.6.2 or 10.5 CM? I have seen many documents online but looking for step by step procedure.

Set Up Peer Firmware Sharing

When enabled, the feature allows the phone to discover like phones on the subnet that are requesting the files that make 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 the files are then rapidly transferred down the transfer hierarchy to the other phones on the subnet that are using TCP connections.

The feature provides the following advantages in high-speed campus LAN settings:

  • Limits congestion on TFTP transfers to centralized remove TFTP servers

  • Eliminates the need to manually control firmware upgrades

  • Reduces phone downtime during upgrades when laree numbers of phones are reset simultaneously

Peer Firmware Sharing may also aid in firmware upgrades in branch or remote office deployment scenarios that run over bandwidth-limited WAN links.

This menu option indicates whether the phone supports peer firmware sharing. Settings include:

  • Enabled, which is the default value.
  • Disabled

Procedure


    Step 1  In Cisco Unified Communications Manager Administration, choose Device > Phone.
    Step 2  Find your phone from the list of phones that associate with the Cisco Unified Communications Manager.
    Step 3  Click on the Device Name of the phone.
    Step 4  Go to Product Specific Configuration Layout area and select Enable from the Peer Firmware Sharing drop-down list.

    The Peer Firmware Sharing is enabled by default.

    Step 5  Check the Override Common Settings check box for any setting in the Product Specific Configuration area that you wish to update.
    • If you do not check this check box, the corresponding parameter setting does not take effect.

    • Parameters that you set in the Product Specific Configuration area may also appear in the Phone Configuration window for various devices and in the Enterprise Phone Configuration window.

    If you set these same parameters in these other windows too, the setting that takes precedence is determined in the following order:

    1. Device Configuration window settings (highest precedence)

    2. Common Phone Profile window settings

    3. Enterprise Phone Configuration window settings (lowest precedence)

    Step 6  Select Save.

     

    Even if its disabled there is not a very lengthy step by step procedure, you can just enable it on the phone configuration page or use BAT for multiple phones or use common device configuration setting to enable it.

    But in your case, it should be enabled by default, you can inspect this from your phone configuration page and common phone profile.

      Terry, do I need to put the device load on all phones as well?

      Hi,

      After installing the firmware on CUCM, go to every phone of similar mode and enable peer firmware sharing ( under Device > Phone > Product Specific Configuration Layout )

      -   Reset all the phones together, which are in the same subnet.

      -   CUCM will randomly select one of them and that phone will become will download
      the firmware and becomes the root, once the download is complete on that phone, the other
      phones will start downloading firmware from this root phone.
