configured, packets from each network layer protocol can be sent over the link. The link remains configured for communications until explicit LCP or NCP packets close the link, or until some external event occurs. This is the actual switch port link type. It may differ from the administrative state. • Disable - Disables point-to-point link. • Auto - The device automatically establishes a point-to-point link. - Point-to-Point Operational Status - Displays the Point-to-Point operating state. - Active Protocol Migration Test - Check to run a Protocol Migration test. This discovers whether the link partner using STP still exists, and if so whether it has migrated to RSTP or MSTP. If it still exists as an STP link, the device continues to communicate with it by using STP. Otherwise, if it has been migrated to RSTP or MSTP, the device communicates with it using RSTP or MSTP, respectively. Defining Rapid STP Parameters Using CLI Commands The following table summarizes the CLI commands for defining Rapid STP parameters as displayed in the Rapid Spanning Tree pages. Table 13-3.
