Associating Track with interface backup

Interface backup allows interfaces on a device to back up each other, with the active interface transmitting data and the standby interfaces staying in backup state. When the active interface or the link where the active interface resides fails, a standby interface takes over to transmit data. This feature enhances the availability of the network. For more information, see "Configuring interface backup."

To enable a standby interface to detect the status of the active interface, you can associate the standby interface with a track entry.
