Configuration changes in PE mode before joining the CB

When the system reboots after you save and reload a Provisional-PE configuration on an ICX 7150, ICX 7250, or ICX 7450 unit, the unit changes from Provisional-PE mode to PE mode. The change in status is visible in the device prompt.

The prefix [Provisional-PE] appears in front of the device prompt for a provisional PE.

The prefix [PE] appears in front of the device prompt when the device enters PE mode.

When a PE is not part of a CB, you can still make and save SPX configuration changes.

Note: When a PE loses its CB, it displays the following message, and you can again enter PE configuration mode: 
T=5m21.2: Spx unit 19 is no longer managed by CB u2 (reason=uplink down).
Note: When a unit boots in PE mode but is not yet attached to the CB, all non-SPX ports on the PE are down, but SPX ports are up. When a PE unit loses its CB, all non-SPX ports on the PE are brought down.

When the PE unit joins a CB, it automatically forms a remote console connection to the CB. The prompt changes to reflect the remote connection. Once a PE has successfully connected to the CB console, you can use the PE unit to manage the Campus Fabric network.
