Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be 
within Round Trip Delay (bit times) in a half-duplex network segment (collision domain). 
For full-duplex operation, this will not be applied. You may use the TP-Fiber module to 
extend the TP node distance over fiber optic and provide the long haul connection. 

A hierarchical network with minimum levels of switch may reduce the timing delay 
between server and client station. Basically, with this approach, it will minimize the 
number of switches in any one path; will lower the possibility of network loop and will 
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. 
Server/Host is recommended to connect to the Level 1 switch. This is general if no VLAN 
or other special requirements are applied. 

Case 1: All switch ports are in the same local area network.     
Every port can access each other. 

 

If VLAN is enabled and configured, each node in the network that can communicate each 
other directly is bounded 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 
difference they are.
