Page 90 xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch Web UI Reference Guide VLAN Description A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout. VLANs can be used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN.
Page 91 xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch Web UI Reference Guide The main characteristics of IEEE 802.1Q are as follows: • Assigns packets to VLANs by filtering. • Assumes the presence of a single global spanning tree. • Uses an explicit tagging scheme with one-level tagging.
Page 92 xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch Web UI Reference Guide The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated.
Page 93 xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch Web UI Reference Guide Tagging and Untagging Every port on an 802.1Q compliant switch can be configured as tagging or untagging. Ports with tagging enabled will put the VID number, priority and other VLAN information into the header of all packets that flow into and out of it.
