Planet ISW-802M [42/60] Redundant ring

To configure the port as an edge port, set the port to "True" status.

6. Admin Non Stp: The port includes the STP mathematic calculation. True is not including STP

mathematic calculation. False is including the STP mathematic calculation.

7. Click

button.

[NOTE] Remember to execute the "Save Configuration" action, otherwise the new configuration will lose

when the switch power off.

RSTP – Per Port Configuration interface

4.16 Redundant Ring

Redundant ring provide a faster redundant recovery than Spanning Tree topology. The action is similar

with STP or RSTP, but the algorithms not the same.

In the redundant ring topology, every switch should enable redundant ring function and assign two

member ports in the ring. Only one switch in the redundant ring group would be set as a backup switch

that one of two member ports would be blocking, called backup port, and another port is called working

port. Other switches are called working switches and their two member ports are called working ports.

When the network connection failure, the backup port will automatically become a working port to

recovery the failure.

The switch supports one Dipswitch for configuring the switch as the ring master or slave mode. The ring

master has the rights to negotiate and place command to other switches in the redundant ring group. If

there are 2 or more switches are in master mode, then software will select the switch with lowest MAC
