Configures TFTP server settings and manages automatic device upgrade processes. This procedure enables administrators to perform manual or scheduled firmware updates via the command line interface.

Procedure

  1. Use the configure tftp server ip-address command to configure the TFTP server IP address.

    Example:

    Device# configure tftp server A.B.C.D

    ip-address : IP address of the TFTP server.

  2. Enable or disable automatic TFTP device upgrades.

    • Use the configure tftp upgrade automatic disable command to disable automatic TFTP device upgrades. 
      Device# configure tftp upgrade automatic disable
    • Use the configure tftp upgrade automatic enable command to enable automatic TFTP device upgrades. 
      Device#configure tftp upgrade automatic enable

  3. Use the configure tftp upgrade check period period command to configure the check period for TFTP device upgrades.

    Example:

    Device# configure tftp upgrade check period 3
    Note

    The check period must be specified in the hours format.

  4. Use the configure tftp upgrade check now command to check for the manifest file immediately.

    Example:

    Device# configure tftp upgrade check now

  5. Use the show tftp config command to verify the TFTP configuration.

    Example:

    Device# show tftp config

The device upgrade procedure fails to start under the following conditions:

  • If the MD5 checksum reported in the manifest file does not match the MD5 checksum calculated on the device image file ( image_name ).

  • If the device image version reported in the manifest file matches the current device version running on the device.

Example of show TFTP configuration:


Device# show tftp config

Status: enabled
Server: A.B.C.D
Check period (hours): 3

Device# configure tftp server A.B.C.D
Device#configure tftp upgrade check period 3
Device#write
Device#configure tftp upgrade automatic enable
