|
|
|
|
| Note | If the new system image is the first file or the only file displayed in the dir bootflash: command output | |
|
|
| in Step 1, you do not need to perform this step. |
|
|
|
|
|
|
| Use this command to load the new system image after the next system reload or power cycle. For |
|
|
| example: |
|
|
| Router(config)# boot system |
Step 5 | (Optional) Repeat Step 4 to specify the order in which the router should attempt to load any backup | ||
|
|
| system images. |
Step 6 | exit | ||
|
|
| Use this command to exit global configuration mode: |
|
|
| Router(config)# exit |
|
|
| Router# |
Step 7 | write | ||
|
|
| or |
|
|
| write memory |
|
|
| Router# write memory |
|
|
|
|
| Note | This step is required beginning with Cisco IOS XE Release 3.9S if upgrading to a later version. Entering | |
|
|
| the write or write memory command updates the GRUB menu list of images available on the bootflash |
|

|
|
| configuration register is between 2 and F, proceed to Step 13. |
Step 10 | configure terminal | ||
|
|
| Use this command to enter global configuration mode: |
|
|
| Router# configure terminal |
|
|
| Router(config)# |
Step 11 |

|
|

|
|
| the router loads a system image from the boot system commands in the startup configuration file: |
|
|
| Router(config)# |
