# Boot Configuration

Device>Configure>Boot Configuration

Use the Boot Configuration function to set MIB variables for booting the device.

Boot With (sysConfigRegister)

Boots the device using one of the following three configuration options:

ROM Monitor - Boots using configuration information in the ROM monitor.

Boot Flash Image - Boots the device from the first bootable system image on the bootflash.

Boot Variable - Boots the device using configuration parameters defined in sysBootVariable. When this option is selected, the Boot Configuration window expands to display a modifiable Boot Variable table .

Using Default Configuration (sysConfigRegister)

Boots the device using the system’s default configuration information when you select the Yes option.

ROM Monitor Console Line Speed (sysConfigRegister)

Sets the console line speed in bits-per-second for ROM Monitor mode. This MIB is not associated with sysBaudRate, which configures the console port speed once the device is running.

Boot Image (sysConfigName)

Displays the filename of the system boot image from which the device last booted (the filename from the Boot Flash Memory Table that the Catalyst 5000 series system is now running)..

Click the Apply button to make your changes take effect.

Command Line Alternative:

Use the following CLI commands to set sysConfigRegister boot configuration:

set boot config-register 0xvalue [mod]

Set boot config-register 1200|2400|4800|9600 [mod]

set boot config-register ignore-configenable|disable [mod]

Boot Variable (sysBootVariable)

A table listing the system boot images (filenames) from the BOOT environment variable with which the system boots the device. Note that the system searches for the earliest entry in the table during the boot process (which is why you can use the Move Up or Move Down buttons to reposition an entry in the table as desired).

Device - a Flash device name indicating your choice of one of the three flash devices available in the Catalyst 5000 series: slot0, slot1 (both from the PCMCI card) and Bootflash (inside the Supervisor III module).

Filename - an image file used by the Catalyst device to boot. No entry in the Filename field means the that the first valid bootable image file (from the Boot Flash Memory Table ) will be used. An invalid filename is one that has been deleted from the Boot Flash Memory table.

Click the Create button to enter another Device and Filename to the Boot Variable Table. In the popup window, select which Flash device you want to boot from (slot0, slot1, or bootflash), enter a valid image filename (one you previously defined within the Boot Flash Memory Table ), then click Apply. An empty filename field indicates to the system that the first invalid file from the device should be used. The newly added entry appears at the end of the table

To delete an entry in the Boot variable Table, select a row, then click the Delete button. To reposition an entry in the table either up or down, click the Move Up or Move Down buttons, respectively.

Be sure to click the Apply button to make your changes take effect.

Click Cancel to close the dialog box. Click Print to print the contents of the dialog box.
