Regardless of the Cisco IOS network device being implemented, there are two methods for connecting a PC to that network device for configuration and monitoring tasks. These methods include out-of-band and in-band management, as shown in the figure.
Out-of-band management is used for initial configuration or when a network connection is unavailable. Configuration using out-of-band management requires:
- Direct connection to console or AUX port
- Terminal emulation client
In-band management is used to monitor and make configuration changes to a network device over a network connection. Configuration using in-band management requires:
- At least one network interface on the device to be connected and operational
- Telnet, SSH, or HTTP to access a Cisco device
