Router Auxiliary Aux Port

The auxiliary (aux) port on a router is an additional console port that can be used for remote management of the router. It is typically used for out-of-band management, which means that it is accessed through a different path than the primary data path of the router.

The aux port is usually a serial port, and it can be used to connect to a modem or other device for remote access. This is useful in situations where the primary data path of the router is unavailable, such as when the router is experiencing network connectivity issues.

The aux port can be configured using the same commands as the console port, and it can be secured with a password to prevent unauthorized access. It is important to keep the password for the aux port secure, as anyone who can access it would have complete control over the router.
