I have a cluster server with one primary server and one secondary server. Both servers are connected to serial ports on a Cisco 1720 router running Cisco IOS<sup></sup> Software Release 12.0. I would like the serial port connected to the secondary server to act as a back up to the primary server (connected to the other serial port). Can I do this by using the backup interface command? Are there other commands I need to use in addition to the backup interface command?
