A Cisco IOS switch can be implemented with no configuration and still switch data between connected devices. By connecting two PCs to a switch, those PCs will instantly have connectivity with one another.
Even though a Cisco switch will function immediately, configuring initial settings are a recommended best practice. There are several ways to access the CLI environment and configure the device. The most common methods are:
Console – This is a physical management port that provides out-of-band access to a Cisco device. Out-of-band access refers to access via a dedicated management channel that is used for device maintenance purposes only.
Secure Shell (SSH) – SSH is a method for remotely establishing a secure CLI connection through a virtual interface, over a network. Unlike a console connection, SSH connections require active networking services on the device including an active interface configured with an address.
Telnet – Telnet is an insecure method of remotely establishing a CLI session through a virtual interface, over a network. Unlike SSH, Telnet does not provide a securely encrypted connection. User authentication, passwords, and commands are sent over the network in plaintext.
