If the OpenBSD host is located in the same physical site as the Cisco products, you have the additional option of providing serial console access to the console port on the Cisco devices through the OpenBSD bastion host. To take this a step further, you can log all serial port I/O to disk. Using the serial console as your management port has one major drawback (some would call it a feature), you can only have one person (two with the AUX port) logged into a given router or switch at a time. This is very much "out of band" management, and having remote serial access is great for fault diagnosis and recovery (Not just for Cisco, Sun, etc). I've resolved more than a few Cisco switch "halt and catch fire" failures based on the last gasp fault message dumped to the console port.
