3.4 Switch Cascading in Topology
Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may uplink an unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with the IEEE 802.3/802.3u and other 802.1 series protocol specifications, which limit the timing requirement from physical signals defined by the Media Access Control (MAC) and PHY802.3 series specification, and the timer from some OSI layer 2 protocols such as 802.1d, 802.1q, and LACP.

3.5 Typical Network Topology in Deployment
A hierarchical network with minimum switch levels may reduce the timing delay between server and client station. This will minimize the number of switches in any one path, lower the possibility of network loops, and improve network efficiency. If more than two switches are connected in the same network, select one switch as Level 1 switch and connect all other switches to it at Level 2. We recommend connecting the Server/Host to the Level 1 switch if no VLAN or other special requirements are used.
Case1: All switch ports are in the same local area network. Every port can access each other (See Figure
Figure 3-3. No VLAN Configuration Diagram.
If VLAN is enabled and configured, each node in the network that can communicate each other directly is bound in the same VLAN area.
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 physical location. The following diagram shows how it works and what the differences are.
