System Validation of Network Changes

The system validates numerous items after any of the following events:

• A PE joins the Campus Fabric domain.
• A PE ages out of the Campus Fabric domain.
• An SPX LAG is updated.
• An SPX port changes state.
• The CB active controller switches over or fails over to the standby controller.

When any of these changes occur, the following items are checked to confirm that the change has been completed successfully for all involved network components.

• SPX ports are shown as being in the correct state on the CB and the PE.
• SPX port hardware configuration is correct.
• SPX topology database is correct.
• SPX LAGs are correct.
• PE virtual ports have been created correctly.
• PE forwarding entries are correct.
• Appropriate PEs are in the Ready state.
• On the standby controller, relevant information has been validated.
