What is a VLAN and what is its purpose? In essence, a VLAN is a collection of devices or network nodes that communicate with one another as if they made up a single LAN, when in reality they exist in one or several LAN segments. In a technical sense, a segment is separated from the...
What is VXLAN? VLAN (Virtual LAN) and VXLAN (Virtual Extensible LAN) are network virtualization technologies used in Layer 2 networks. While both serve the purpose of network segmentation and isolation, they differ in several key aspects.
How to manage and configure VLANs The purpose of a virtual LAN is to provide a helpful layer of intercommunication within LANs and associated devices. Switch ports are essential components of this type of network configuration and help group multiple devices from distinct LANs. This way, communicat...
When using a switch, it will make a frame forwarding decision based on the destination MAC address used in the MAC-header. Since a switchport is its own collision domain it means a frame will be forwarded between multiple network segments. The frame can be sent as a unicast frame, a multi...
A VLAN is identified on network switches by a VLAN ID. Each port on a switch can have one or more VLAN IDs assigned to it and will land in a default VLAN if no other one is assigned. Each VLAN provides data-link access to all hosts connected to switch ports configured with its VLAN...
Virtual LAN (VLAN) is a type of LAN that segments a physical network into multiple logical networks. This segmentation is achieved through software configurations on network switches and routers, allowing devices on separate VLANs to communicate as if they were on the same physical network. VLANs...
The main purpose of a switch is to forward data and implement communication and interconnection between network devices. The functions are described as follows: Segments a network into multiple isolated local area networks (LANs) or virtual local area networks (VLANs) to improve network security. ...
You can specify a number for a created ACL. Different types of ACLs have different number ranges, as described inTable 1-1. You can also specify a name for the created ACL to help you remember the ACL's purpose. A named ACL consists of a name and number. That is, you can specify ...
