Chapter 7 Advanced Chapter 7 Advanced VLAN A VLAN (Virtual Local Area Network) is a group of devices that form a logical LAN segment, that is, a broadcast domain. The members on the same VLAN can communicate with each other. The traffic will not disturb among different VLANs, that is, any traffic (unicast, broadcast or multicast) within a VLAN doesn’t flow to another VLAN. - Page 37 Chapter 7 Advanced same VLAN can communicate with each other, but they are unable to communicate with ports on different VLANs. End-user hosts become members in a VLAN based on the switch port to which they are connected. To enable port-based VLAN on the Switch, select Port VLAN from the VLAN Mode drop-down list, and then click the Save button.

Page 45: Lacp
Chapter 7 Advanced LACP 7.3.1 Introduction LACP Link Aggregation Control Protocol (LACP) is part of IEEE 802.3ad which is used to bundle several physical ports together to form a single logical channel, known as a Link Aggregation Group (LAG) or bundle. LACP allows two switches to exchange Link Aggregation Control Protocol Data Units (LACPDUs) to negotiate a LAG automatically. -
Page 46: Lacp Settings
Chapter 7 Advanced For example, if you want to aggregate Port 2, 3, 4 and 5 on the local GEL-2461 Switch and those on the remote switch together to form a dynamic LAG, you only need to enable LACP on Port 2, 3, 4 and 5 respectively, and leave their Admin Key at the default value of auto, see Figure 7-12. -

Chapter 7 Advanced Quality of Service (QoS) is a technology which uses various mechanisms to decrease the negative effects of network congestion to improve network performance. For example, using QoS can guarantee a required delay and packet dropping probability to various real-time applications (video, audio, etc.) when network congestion occurs. -

Page 50: Link Aggregation Settings
Chapter 7 Advanced total bandwidth is approximately the sum of the individual switch ports. For example, there is a 100Mbps switch device, a LAG containing two ports will have 200Mbps bandwidth, and a LAG containing four ports will have 400Mbps bandwidth. Link aggregation provides a higher performance logical link, as well as providing a fault-tolerant link between two devices. -
Page 51: Linkage Management
Chapter 7 Advanced All ports in a LAG must belong to the same VLAN, and must have the same tag VLAN port settings (configured in the Advanced > VLAN > VLAN Port Settings page) if you enable tag-based VLAN on the Switch. A LAG can’t contain the mirroring port. - Page 52 Chapter 7 Advanced Port: It displays the local Switch’s port to which the remote switch is connected.
