The switchport mode access command configures a port as an access port, allowing devices connected to this port to be assigned to a specific VLAN.

The switchport access vlan command assigns a VLAN to an access port, allowing all devices connected to that port to communicate within the VLAN.

The no vlan vlan-id command removes a VLAN from the switch's configuration, effectively deleting it.

The show vlan brief command displays a summary of all VLANs configured on the switch, including the VLAN name, status, and ports assigned to it.

The show interfaces command allows you to view detailed information about a specific interface or a range of interfaces on the switch, including its status, configuration, and VLAN membership.

The show vlan id command displays detailed information about a specific VLAN, including its name, status, description, ports, and other related configuration parameters.

The show vlan name command displays detailed information about a specific VLAN identified by its name.

The show vlan summary command displays a summary of all VLANs currently configured on the switch, including information such as VLAN ID, name, status, and associated ports.

A virtual interface associated with a physical interface. Subinterfaces are used to separate network traffic for different VLANs.

A physical interface must be enabled for its associated subinterfaces to function.

A port on a switch that allows multiple VLANs to share the link. It's used to connect to routers that support VLANs.

The show vlan command shows the VLANs on the switch and their associated ports. A trunk port will be listed as part of all the VLANs it carries.

The show interface trunk command displays details about the trunk ports on the switch, including the VLANs being carried.

A virtual LAN that allows devices on the same network to communicate with each other, regardless of their physical location.

The default VLAN that all ports belong to when a switch is first powered on. Typically VLAN 1.

The VLAN that is used when a trunk port is first initialized. Typically VLAN 1, but can be changed.

A configuration error that occurs when two trunk ports have different native VLANs. Can cause connectivity issues.

A command that is used to display information about the configured VLANs on a switch.

A command that is used to display information about the trunk interfaces on a switch.

A command that is used to display information about the switchport configuration of an interface on a switch.

A method of forwarding network traffic between different VLANs using a router, where each VLAN is connected to a separate physical router interface.

A method of forwarding network traffic between different VLANs using a single physical router interface, configured as a trunk port, with logical subinterfaces representing each VLAN.

A specialized switch port on the router that allows it to handle data traffic from multiple VLANs simultaneously.

A virtual interface on a router, configured to represent a specific VLAN and assigned an IP address from that VLAN.

A network device that connects different network segments and forwards traffic between them based on routing tables.

A group of devices connected to a network that share a common set of network settings, such as the same subnet mask.

A protocol that adds tags to network frames to identify the VLAN to which they belong.

The default gateway address used by network devices within a VLAN to access other networks.

A network switch configuration that allows for communication between different VLANs by encapsulating data packets within VLAN tags.

A physical port on a switch that allows communication with devices on a specific VLAN.

A technique used to identify and encapsulate network traffic belonging to specific VLANs by adding 4 bytes of tag information to the Ethernet frame.

A logical interface created on a router to handle network traffic associated with a specific VLAN.

A network device, typically a router, that forwards network traffic between different VLANs, providing connectivity between various network segments.

A process that dynamically assigns VLAN tags to incoming traffic based on preconfigured rules, enabling communication between VLANs.

A trunk is a connection between two network devices that allows multiple VLANs to be carried over a single link.

If the native VLAN settings on two trunks connected to each other do not match, it can create security risks and unexpected behavior.

If the trunk modes on two connected devices don't match (e.g., one is set to dynamic auto and the other is set to static), it can cause loss of network connectivity.

An allowed VLANs list defines which VLANs are allowed to send traffic over a trunk. If the list doesn't support current VLAN trunking requirements, unexpected or no traffic can occur.

Inter-VLAN routing is the process of forwarding network traffic between different VLANs using a routing device, such as a router or a Layer 3 switch.

Layer 2 switches are limited in their ability to perform dynamic routing, and therefore cannot handle a large number of VLANs.
