Overview
Setting up virtual LANs (VLANs) is a way to segment networks to increase network flexibility
without changing the physical network topology. With network segmentation, each switch port
connects to a segment that is a single broadcast domain. When a switch port is configured to be
a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast
domain.
Ports are grouped into broadcast domains by assigning them to the same VLAN. Frames
received in one VLAN can only be forwarded within that VLAN, and multicast, broadcast, and
unknown unicast frames are flooded only to ports in the same VLAN. The G8000 supports
jumbo frames up to 9,216 bytes.
