Automatic Synchronization Of Configuration Files; Accessing The Bootloader - Extreme Networks ExtremeWare XOS Guide Manual

CAUTION
During a synchronization, half of the switch fabric is lost. When the primary MSM finishes replicating its
configurations and images to the backup MSM, the full switch fabric is restored.
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
configuration first.
Additional Behavior on the Aspen 8810 Switch Only
On the Aspen 8810 switch, the I/O ports on the backup MSM go down when you synchronize the
MSMs. When the primary MSM finishes replicating its configurations and images to the backup MSM,
the I/O ports on the backup MSM come back up.

Automatic Synchronization of Configuration Files

On a dual MSM system, ExtremeWare XOS automatically synchronizes all of the configuration files
from the primary MSM to the backup MSM if the switch detects that the backup MSM's configuration
file contents are different from the primary MSM. You do not configure this behavior.
The switch deletes the old configuration files on the backup MSM only upon a successful file
synchronization. If an error occurs, the switch does not delete the old configuration files on the backup
MSM. For example, if you install a backup MSM that contains different configuration files from the
primary MSM, the old configuration files are deleted after a successful bootup of the backup MSM.

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.
