5. Redundant Ring Application
5.1 Auto Multi-Ring Technology for 4-Port Switch Mode
Auto Multi-Ring Technology was developed especially for switches connected in a ring topology which needs
redundant support when any failure occurs in the ring. For large networks, more than one ring connection are
very common. Auto Multi-Ring Technology implementation can support more than one ring connection within a
switch. It is also able to work with RSTP support concurrently in the switch.
Some basic information is:

Supports up to two rings in one switch

Supports ring member status monitoring for up to 100 member switches in one ring

Supports ring connection for up to 250 switches

Auto backup is activated when one or more than one fault occur

Auto recovery when fault is repaired (Limited in cases of more than one faults)

Provides fast response time than RSTP protocol

Works with RSTP protocol concurrently within one switch
