Note: For proper functionality, the switch must be at the switch firmware version shown in Table 2
before proceeding with this configuration. Using previous firmware versions may have unpredictable
results.
The latest firmware updates and documentation can be found at: www.force10networks.com. This site
requires a login.
Note: Firmware version 9.8.0.0 incorporates new command-line syntax for DCB configuration. To
configure a new switch for DCB operation, follow the configuration steps in this Switch Configuration
Guide as outlined below.
If you are upgrading from Dell firmware version prior to 9.8.0.0, your DCB settings in the running
configuration file will be preserved and you may continue to use the original DCB command-line syntax.
If you make changes using the previous DCB command-line syntax, you will receive a warning message
that the commands have been deprecated, however the commands will still continue to function as they
did with the previous version.
