EtherWAN α-Ring Technology
The α-Ring protocol was designed and developed by EtherWAN to overcome traditional
STP and RSTP’s inability to provide fast network recovery and minimize packet loss caused
by link failure. Among the advantages of α-Ring are:

High-speed Recovery
– Less than 15 milliseconds

Flexibility for Network Deployment
– Coexistence with STP, RSTP and MSTP

Ring Coupling
– Smaller rings coupled together to increase network efficiency
Implementing a Simple α-Ring
1. Change the Ring State to Enabled
2. Click on the Update Setting button.
Next, the ports that will be used to connect this switch to the α-Ring need to be assigned to
provide the connection redundancy (see
Figure 67 ).
1. Change Ring Port 1 to the port you will be using for the first redundant connection
2. Change Ring Port 2 to the port you will be using for the second redundant
connection.
3. Click on the Update Setting button.
4. Save the configuration (see the Save Configuration Page )
