Switchport mode allows for the configuration of a port into certain settings. A few examples are Access, Trunk, and Dynamic. Each mode allows for different functions. Access mode is used for end devices, this allows for certain port security settings. Trunk mode is used for lines between switches and other lines that send multiple VLANs over a single connection. Dynamic will automatically detect what kind of device is connected and initiate its port accordingly.
A trunk link is formed if the remote connected device is configured with the switchport mode dynamic auto or switchport mode trunk commands.
To configure a VLAN on a switch port, first access the switch's command-line interface (CLI) via console or SSH. Enter configuration mode by typing configure terminal, then select the specific interface using interface [type][number] (e.g., interface FastEthernet0/1). Assign the VLAN to the port with the command switchport access vlan [VLAN_ID], and if needed, set the port to access mode using switchport mode access. Finally, save the configuration with write memory or copy running-config startup-config.

A switchport refers to a specific port on a network switch that allows devices to connect to the switch for data communication. It can operate in different modes, such as access mode for connecting end devices or trunk mode for linking switches. Each switchport can be configured with various settings, including VLAN assignments and security features, to manage network traffic effectively. Switchports play a crucial role in local area networks (LANs) by facilitating the flow of data between devices.

To configure VLANs on switches in a switched LAN, first, access the switch's command-line interface (CLI) or web-based management interface. Create the desired VLANs using the command vlan [VLAN_ID] and assign a name if needed. Next, assign switch ports to the VLANs using the command interface [interface_id] followed by switchport mode access and switchport access vlan [VLAN_ID]. Finally, save the configuration to ensure it persists after a reboot.
