• After the restore is complete, a switch reloads immediately.

default settings.

Restoring Factory-Default Boot Environment Variables
The Boot line determines the location of the image that is used to boot up the switch after restoring
factory-default settings. Ideally, these locations contain valid images, which the switch uses to boot up.
When you restore factory-default settings, you can either use a flash boot procedure or a network boot
procedure to boot the switch.
When you use a flash boot procedure to boot the switch, the reset boot variables are displayed below
restore bootvar in the command output.
• If the primary boot line is A: and the A: partition contains a valid image, the primary boot line is set to
A:, the secondary boot line is set to B: (if B: also contains a valid image), and default boot line is set to
a Null String.
• If the primary boot line is B: and the B: partition contains a valid image, the primary boot line is set to
B:, the secondary boot line is set to A: (if A: also contains a valid image), and default boot line is set to
a Null string.
• If either partition contains an invalid or corrupted image, the partition is not set in any of the boot
lines. If both partitions contain invalid images, the primary, secondary, and default boot lines are set to
a Null string.
When you use a network boot procedure to boot the switch, the reset boot variables are displayed below
restore bootvar in the command output.
• If the primary partition contains a valid image and the secondary partition does not contain a valid
image, the primary boot line is set to A: and the secondary and default boot lines are set to a Null
string.
• If both partitions have valid images, the primary boot line value is set to the partition configured to
boot the device in case of a network failure. The secondary and default boot lines are set to a Null
string.
Important Points to Remember
• The CLI remains at the boot prompt if no partition contains a valid image.
