A switch's interface typically refers to the physical ports on the switch through which devices connect, allowing for data transmission within the same local network. In contrast, a VLAN (Virtual Local Area Network) interface is a logical interface associated with a specific VLAN, enabling Layer 3 IP routing and communication between different VLANs. While switch interfaces handle traffic for individual devices, VLAN interfaces manage traffic for groups of devices segmented by VLANs, enhancing network organization and security.

What is the difference between vlan and inter-vlan?
VLAN is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. Inter VLAN is defined as two VLANS connected to each other and communicating.
How many physical interfaces are required to perform inter-VLAN routing with traditional inter-VLAN routing?
In traditional inter-VLAN routing (also known as "router-on-a-stick"), only one physical interface is required on the router. However, this single physical interface needs to be configured with multiple sub interfaces, each corresponding to a different VLAN. The router uses these sub interfaces to route traffic between VLANs. The configuration involves: One physical interface on the router (e.g., GigabitEthernet0/1). Multiple sub interfaces (e.g., GigabitEthernet0/1.10, GigabitEthernet0/1.20) corresponding to different VLANs. Each sub interface is assigned an IP address in the respective VLAN's subnet. This setup enables inter-VLAN routing by allowing the router to route traffic between the VLANs using a single physical interface.

How can configure VLAN on a switch port?
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.
What must the network administrator do to remove Fast Ethernet port fa01 from VLAN 2 and assign it to VLAN 3?
To remove Fast Ethernet port fa01 from VLAN 2 and assign it to VLAN 3, the network administrator should first enter the interface configuration mode for the port by typing interface fa01. Then, the command switchport access vlan 3 should be executed to change the port's VLAN assignment. This action automatically removes the port from VLAN 2, as a port can only belong to one VLAN at a time in access mode. Finally, the changes can be saved with the write memory or copy running-config startup-config command.
What is a router on stick inter vlan routing?
A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.
What is Difference between access link and trunk link?

Which interface allows remote management oa layer 2 switch?
The interface that allows remote management of a Layer 2 switch is typically the Switch Management Interface (also known as the Management VLAN or Management Interface). This interface is often configured on a specific VLAN, allowing network administrators to access the switch's management features via protocols such as SSH, Telnet, or HTTP/HTTPS. By connecting to this interface, administrators can configure settings, monitor performance, and troubleshoot issues remotely.
When implementing a router-on-a-stick what must be configured on the router to ensure connectivity?
When implementing a router-on-a-stick configuration, you must create sub-interfaces on the router's physical interface connected to the switch, with each sub-interface assigned to a different VLAN. Each sub-interface should be configured with an IP address corresponding to its VLAN's subnet, and the encapsulation type (usually 802.1Q) must be specified for each sub-interface. Additionally, ensure that the switch ports connected to the router are set to trunk mode to allow multiple VLAN traffic to pass through the link.
Which set of commands will enable a network administrator to remotely manage a LAN switch?
Switch(config)# ip default-gateway 192.168.1.254Switch(config)# interface vlan 1Switch(config-if)# ip address 192.168.1.1 255.255.255.0Switch(config-if)# interface fa0/1Switch(config-if)# switchport access vlan 1
How do you configure vlan on switches in a switched lan?
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.
How do you connect computers on separate VLAN?
Since VLAN's cannot communicate with other VLAN's directly, I believe you would have to set up a router to do that. I would check out how to set up a bridge between two VLAN's.
