Page 20: Vlan Setting
VLAN Setting A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would allows user to isolate network traffic so only the members of VLAN will receive traffic from the same members of VLAN. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. - Page 21 PVID: Enter the Port VLAN ID Awareness: Enable: Transmit to the PVID group that the same with the packets’ VID. Disable: Transmit to the PVID group that the same with the incoming port’s PVID. Frame Type: Tag: Only allow tagged frame pass the port. All: Allow all type of frames pass through.

Page 22: Aggregation
VLAN Port Setting interface 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. -

that called a hash algorithm. Traffic pattern on the network should be considered carefully before applying it. When a proper hash algorithm is used, traffic is kind of randomly decided to be transmitted across either link within the trunk and load balancing will be seen. - Page 24 orderly manner. Link aggregation allow user grouping up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode, more detail information refers to IEEE 802.3ad.
