to connect with a core managed switch easily and conveniently. With RDH
technology, you can also couple several Rapid Super Rings or RSTP cloud together,

LACP/Trunk aggregated ports is a virtual interface and it can work as the Ring port
of the MSR.
MultiRing can be aggregated within one switch by using different Ring ID. The
maximum Ring number one switch can support is half of total port volume. The
feature saves much effort when constructing complex network architecture.
This page allows you to enable the settings for Multiple Super Ring and Rapid
Dual Homing.
