Chapter 3: Software Description 3.2.3 VLAN A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would allow you to isolate network traffic, so only the members of the same VLAN will receive traffic from the members of the same VLAN. Basically, creating a VLAN from a switch is logically equivalent to reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plugged into the same switch physically. 3.2.3.

Chapter 3: Software Description Figure 3-6. 3.2.3.3 VLAN Per Port Configuration The 802.1Q Per Port Configuration page allows you to change the VLAN parameters for individual ports or trunks. You can configure VLAN behavior for specific interfaces, including the accepted frame types and default VLAN identifier (PVID). Each row of the table corresponds to one port or trunk; trunked ports cannot be configured individually; configure the trunk instead. Figure 3-7. VLAN per port configuration.

Chapter 3: Software Description • Port/Trunk: The port number of the port or the ID of a trunk. • VLAN Aware Enabled: VLAN aware ports are able to use VLAN tagged frames to determine the destination VLAN of a frame. (Default: Enabled) • VLAN aware ports will strip the VLAN tag from received frames and insert the tag in transmitted frames (except for the PVID). VLAN unaware ports will not strip the tag from received frames or insert the tag in transmitted frames. • Ingress Filtering Enabled

Chapter 3: Software Description 3.2.4 Aggregation Port trunk allows multiple links to be bundled together and act as a single physical link for increased throughput. It provides load balancing, and redundancy of links in a switched inter-network. Actually, the link does not have an inherent total bandwidth equal to the sum of its component physical links. Traffic in a trunk is distributed across an individual link within the trunk in a deterministic method that called a hash algorithm. The
