The checksum of the downloaded binary is shown:
08761cd03e33c569873bcc24cf2b7389 7006920 LIS-15.00.72.002 This MD5
To verify the checksum of written firmware, enter:
va_image_csum.sh alt
After a while the checksum will be calculated:
Calculating checksum.........
08761cd03e33c569873bcc24cf2b7389 7006920 LIS-15.00.72.002 This MD5
Verify and compare the checksum with the MD5 sum of the downloaded image.
If the checksum of the written firmware in altimage matches the one from the
downloaded image in /tmp, the new firmware has been programmed successfully.
9.2.5
Setup an alternative image
Provided the programming has succeeded, you can set it as the next image to use after
reboot; enter:
vacmd set next image altimage
To reboot using the new firmware, enter:
reboot
9.3
Firmware recovery
The router has an automatic boot recovery feature that will
•
revert the active firmware to the alternate firmware segment on three
consecutive failed software restarts.
•
Change the boot configuration to factory configuration after ten failed restarts
By design this feature is intended to allow recovery from firmware problems and
therefore excludes restarts due to power loss.
