Page 85 xStack® DGS-3120 Series Layer 3 Managed Gigabit Ethernet Switch Web UI Reference Guide VLANs can enhance performance by conserving bandwidth, and improve security by limiting traffic to specific domains. A VLAN is a collection of end nodes grouped by logic instead of physical location. End nodes that frequently communicate with each other are assigned to the same VLAN, regardless of where they are physically on the network.
Page 86 xStack® DGS-3120 Series Layer 3 Managed Gigabit Ethernet 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.
