Unconfiguring the CB Stack or PE Units

The spx unconfigure command can be used to convert PE units to regular switches or routers or to remove SPX configuration from all CB and PE units.

Removing SPX Configuration from PE Units

You can remove SPX configuration from a PE unit locally using the spx unconfigure me command. When a PE joins an SPX system, the PE unit's local console is redirected to the CB's console. The PE console returns to its local console if it loses connection to the CB. The spx unconfigure me command is only available to a PE local console.

The spx unconfigure me command removes the PE startup file from the PE unit on which the command is issued. The startup configuration file for regular mode is not affected. If the PE is in PE mode (with a prompt prefix of [PE]), it reloads. A device in regular mode or in Provisional-PE mode (with a [Provisional-PE] prefix on the prompt) does not reload.

You can also remove PE configuration from the CB using the PE ID in the spx unconfigure id command. This form of the command can be entered only from the CB. The command removes the PE startup file of the specified PE and reloads the unit as a switch or router from the regular startup file.

The following example shows system response when the spx unconfigure me command is entered on an active PE. 

[PE]ICX7450-24 Router# spx unconfigure me
This unit will remove the PE startup file and reload as a standalone. Are you sure? (enter 'y' or 'n'): y

Removing SPX Configuration from All Units

The spx unconfigure all command can be issued only on a CB. This form of the command removes the SPX startup file of every PE and CB unit in the Campus Fabric domain. It also reloads all PE units. The CB unit from which the command is issued and other CB units in the domain are not reloaded.

The following example removes all SPX configuration from all units. 

ICX7650-48F Router# spx unconfigure all
Will remove all spx unit PE startup files and reload them. Are you sure? (enter 'y' or 'n'): y
Sent unconfigure messages to spx unit 17 18

Removing Stacking Configuration

Note: It is not necessary to remove stacking configuration before enabling a PE unit. However, if stacking is enabled on the unit, it must be disabled before the PE is enabled and configured.
Because PE units do not participate in the stack election process, startup configuration is never synched to these units. As a result, the regular startup configuration file never changes when a PE unit becomes part of a Campus Fabric domain, and the configuration is available later if the PE unit is converted to regular mode.

For more information on unconfiguring a stack unit, refer to the RUCKUS FastIron Stacking Configuration Guide.
