Figure C 1 Two Switch VLAN Configuration Compaq SW3322 SW3323 Dual Speed Switch User Guide C 2 Virtual Lans VLANs If the switch is so configured a unique VLAN identifier is placed in a tag appended to the packet when it is received by the switch from end station nodes if the packet does not already contain this information The tag is then stripped off when the packets are forwarded to the destination end stations Within the switch and between switches compliant with IEEE 802 1Q these identifiers are used to control the destination of broadcast frames and to prevent flooding these broadcasts to all ports and connected interfaces Broadcast multicast traffic from geographically dispersed stations can be directed across these links without radiating out to stations that are not part of the same VLAN Up to 4094 different VLANs can be carried across these links thus permitting the configuration of up to 4094 virtual workgroups This approach is nonintrusive to end station applications and the associated clients You can configure VLANs using the VLAN Menu in the console interface and associated submenus or via SNMP VLAN Access Ports SW3322 SW3323 S W3324 ports can be configured as one of two types for the purpose VLAN configuration access or hybrid A VLAN access port is used to connect one or more VLAN unaware devices into a port of a VLAN device There can be no VLAN tagged frames entering an access port If a tagged frame does arr
