13211 – VLANCreate separate network segments (collision domains) across Magnum 6K family ofswitches…..hort for virtual LAN (VLAN), a VLAN creates separate collision domains or networksegments that can span multiple Magnum 6K family of switches. A VLAN is a group of portsdesignated by the switch as belonging to the same broadcast domain. The IEEE 802.1Qspecification establishes a standard method for inserting VLAN membership information intoEthernet frames.WVcohy VLANs?LAN’s provide the capability of having two (or more) Ethernet segments-exist on common hardware. The reason for creating multiple segmentsin Ethernet is to isolate collision domains. VLANs can isolate groups ofusers, or divide up traffic for security, bandwidth management, etc. VLANs are widelyused today and are here to stay. VLANs need not be in one physical location. They can bespread across geography or topology. VLAN membership information can be propagatedacross multiple Magnum6K switches.F IGURE 78 – VLAN as two separate collision domains.
