Configuring the ACE to Autoboot the Software Image
After you copy the image on to the ACE, configure it to autoboot the image by
setting the boot variable and the configuration register. The boot variable specifies
the image from which the ACE boots at startup. The configuration variable can be
set to autoboot the image defined by the boot variable.
This section contains the following topics:
•
Setting the Boot Variable
•
Configuring the Configuration Register to Autoboot the Boot Variable
•
Verifying the Boot Variable and Configuration Register
For detailed information on the boot variable and configuration register, see
Chapter 1, Setting Up the ACE
.
Setting the Boot Variable
To set the boot variable, use the
boot system image:
command in the Admin
context from the configuration mode. The syntax for this command is:
boot system image:
image_name
The
image_name
argument is the name of the installed image.
You can set up to two images through the
boot system
command. If the first image
fails, the ACE tries the second image.
For example, to set the boot variable with the c4710ace-t1k9-mz.A1_7.bin image,
enter:
host1/Admin(config)#
boot system image:c4710ace-t1k9-mz.A1_7.bin
Use the
no boot system image:
command to unset the previously configured boot
variable.
