Enabling Automatic Reset of FSC Fabric

For additional information, refer to the Exec Mode Commands chapter in the Command Line Interface
Reference.
Beginning with Release 15.0, the chassis ID will be generated from the chassis key using a more secure
algorithm. The resulting 44-character chassis ID will be stored in the same file.
Release 14 and Release 15 chassis IDs will be in different formats. Release 15 will recognize a Release 14
chassis ID and consider it as valid. Upgrading from 14.x to 15.0 will not require changing the chassis ID or
configuration file.
However, if the chassis key is reset in Release 15 through the Quick Setup Wizard or CLI command, a new
chassis ID will be generated in Release 15 format (44 instead of 16 characters). Release14 builds will not
recognize the 44-character chassis ID. If the chassis is subsequently downgraded to Release 14, a new
16-character chassis ID will be generated. To accommodate the old key format, you must save the configuration
file in pre-v12.2 format before the downgrade. If you attempt to load a v15 configuration file on the downgraded
chassis, StarOS will not be able to decrypt the password/secrets stored in the configuration file.
For release 19.2 and higher, in a chassis where the chassis ID file already exists nothing is changed. However,
if the chassis ID file is lost in both management cards, all existing configuration files become invalid. Entering
a new chassis key that is the same as the original value will not resolve the issue because of the new method
used to generate the chassis ID.
After setting a new chassis key, you must save the configuration before initiating a reload. See the Verifying
Caution
and Saving Your Configuration chapter.

Quick Setup Wizard

The Quick Setup Wizard prompts the user to enter a chassis key value. If a chassis key value is not entered a
default chassis is generated using the chassis' MAC address (releases prior to 20.0).
For releases 20.0 and higher, if the chassis ID file does not exist, the Quick Setup Wizard prompts the user
to enter a chassis key. A default chassis ID is not generated if a chassis key is not entered.
To run the Quick Setup Wizard, execute the Exec mode setup command.

Enabling Automatic Reset of FSC Fabric
By default if an excessive number of discarded fabric egress packets occurred in the switch fabric, a manual
reset of the Fabric Storage Card(s) is required for fabric recovery.
You can optionally enable automatic resets of FSCs if an excessive number of discarded fabric egress packets
is detected.
A Global Configuration mode fabric fsc-auto-recover command enables or disables automatic FSC resets
upon detection of an excessive number of discarded fabric egress packets.
