VLAN Overview
A virtual LAN (VLAN) is used to partition a computer network at Layer 2 into a broadcast domain, which is uniquely identified by a VLAN ID. A VLAN splits a physical network into multiple logical networks, with each VLAN functioning as an independent network while remaining connected to the same physical infrastructure. Using VLAN tagging, the network administrators can virtually group networks together even if the networks are not physically connected to the same network switch.
Based on various parameters like users, groups, or roles, VLAN can be used to segment traffic on a network. Based on network requirements, administrators can securely scale VLANs to manage traffic and maintain efficient network performance.
The following sections provide details about the VLAN types and features supported on the RUCKUS family of switches.
VLAN Support on RUCKUS Devices
RUCKUS ICX devices support Layer 2 port-based VLANs, which consist of a group of physical ports that share a common, exclusive Layer 2 broadcast domain. When a RUCKUS ICX device receives a packet on a port that is part of a VLAN, it determines whether the packet can be forwarded at Layer 2. If Layer 2 forwarding is possible, the device sends the packet to all other ports within the same VLAN as the receiving port.
