Step 2: Configure basic switch settings.
In this step, you will configure basic switch settings, such as hostname and configuring an IP address for the SVI. Assigning an IP address on the switch is only the first step. As the network administrator, you must specify how the switch will be managed. Telnet and Secure Shell (SSH) are two of the most common management methods; however, Telnet is a very insecure protocol. All information flowing between the two devices is sent in plain text. Passwords and other sensitive information can be easily looked at if captured by a packet sniffer.
