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.
