Typical Network Topologies
A network with the lowest number of levels of switches will reduce the timing delay between server and
client. With this approach, the number of switches in any one path will be minimized, lowering the
possibility of a network loop and improving network efficiency. If more than two switches are connected in
the same network, select one switch as the Level 1 switch and connect all other switches to it at Level 2.
It is recommended to connect the servers to the Level 1 switch. This is a general case if no VLANs or
other special requirements are applied.
Case 1: All ports are in the same local area network. Every port can access each other (See Figure 2-3).
Figure 2-3 No VLAN Configuration Diagram
If VLANs are enabled and configured, each node in the network can only communicate with other nodes
in the same VLAN.
Here VLAN area is defined by what VLAN you are using. The switch supports both port-based VLAN and
tag-based VLAN. They are different in practical deployment, especially in terms of physical location. The
following diagram shows how each on works and the differences between the two.
