Software Upgrade and Boot Options
If the configuration currently running in the switch does not match the configuration that the switch
used when it originally booted, an asterisk (*) appears before the command line prompt when using the
CLI.
Synchronizing MSMs
On the BlackDiamond switch, you can take the master MSM configurations and images and replicate
them on the backup MSM using the following command:
synchronize
In addition to replicating the configuration settings and images, this command also replicates which
configuration or image the MSM should use on subsequent reboots. This command does not replicate
the run-time configuration. You must use the
save configuration command to store the run-time
configuration first.
Accessing the Bootloader
The Bootloader of the switch initializes certain important switch variables during the boot process. In
the event the switch does not boot properly, some boot option functions can be accessed through the
Bootloader.
Interaction with the Bootloader is required only under special circumstances and should be done only
under the direction of Extreme Networks Customer Support. The necessity of using these functions
implies a nonstandard problem which requires the assistance of Extreme Networks Customer Support.
To access the Bootloader, follow these steps:
1 Attach a serial cable to the console port of the switch.
2 Attach the other end of the serial cable to a properly configured terminal or terminal emulator,
power cycle the switch, and press the spacebar key on the keyboard of the terminal during the
bootup process.
NOTE
To access the Bootloader, you have to press the spacebar key immediately after a power cycle of
the MSM in order to get into the Bootloader application.
As soon as you see the
BOOTLOADER> prompt, release the spacebar. You can issue a series of
commands to:
— View the installed images
— Select the image to boot from
— Select the configuration to use
