Advanced Dual Homing

EKI managed switches support Dual Homing for connecting with another

network which runs RSTP (Rapid Spanning Tree Protocol) or MSTP (Multiple

Spanning Tree Protocol). Dual Homing means an EKI switch is connected

to a network with two independent connecting paths. The standby path

will be actuated when the primary path fails. Thus, users can connect 2

paths to the same switches, or switches on different levels of the network

architecture. This is a convenient way for the network planner to expand

the network without replacing existed devices.

RSTP/MSTP

Dual Ring

Multiple rings can be aggregated by one central switch. This provides

centralized management and saves costs.

Multi-Couple Rings

Multiple rings can be connected via 2 links, one is

active and another one is standby one. This largely

increases the ring communication redundancy.
