Setting up the Ring Environment
The Ring topology is used to guarantee the network being normal even if one link
between two device broken. So, in ring topology, the network will work well if one
link is broken. In Ring Topology, you must enable RSTP/STP to prevent the loop
issue.
How to set up a Ring Environment.
We set up Ring environment with one IES-5000, one IES-2000 and one ES-4024. A
PC behind IES can connect the PC in the network even one of the links broken.
Following sections will describe the detailed procedures to set up the environment.
