Stacking Ports Displayed Even When Stacking Is Not Enabled

In FastIron releases prior to 08.0.90, when stacking is not enabled, the system does not display factory-default stacking ports in show running-config command output. However, in these releases, if the stacking ports have been changed, they are displayed. In contrast, FastIron release 08.0.90 always displays stacking ports in show running-config command output, regardless of whether stacking is enabled or whether the stacking ports are set to factory default or have been changed.

In all FastIron releases, when stack enable is not configured, the stacking ports are available for use as data ports and may contain any data port configuration such as tagged ports.

Note: FastIron release 08.0.90 corrects the difficulty of configuring stacking ports as breakout ports that was present in previous releases.
Note: Beginning with FastIron release 08.0.90, any stacking port can serve as a breakout port as long as the stack enable command is not configured. However, the stacking ports are always displayed in three-tuple format (x/y/z) even when they have been configured as breakout ports. For example, if port 1/2/1 is a breakout port, it appears in general configuration or show command output as 1/2/1:1; however, any output that shows the port as stack-port configuration displays the port as 1/2/1.

In all releases, when you enter the stack enable command, the system checks all stacking ports to make sure they contain no configuration. If any configuration is present, the stack enable command is denied.
