Note:
We don’t suggest you to set one switch as a Ring Master and a Coupling Ring at the same time due to heavy
load.
4.1.4.2 OPEN-Ring
Open-Ring technology can be applied for other vendor’s proprietary ring. Thus, you can
add switches of ORing into the network constructed by other ring technology and enable
Open-Ring to co-operate with other vendor’s managed switch.
