Ring/Network Coupling
 Activate the function in the "Operation" frame
The displays in the "Select port" frame mean:
– "Port mode": The port is either active or in stand-by mode.
– "Port state": The port is either connected or not connected.
– "IP Address": The IP address of the partner, if the partner is already
operating in the network.
The displays in the "Information" frame mean:
– "Redundancy guaranteed": If the main line no longer functions, the
redundant line takes over the function of the main line.
– "Configuration failure": The function is incomplete or incorrectly
configured.
To avoid continuous loops, the Switch sets the port state of the coupling
port to "off" if you::
– switch off operation or
– change the configuration
while the connections are in operation at these ports.
Note: The following settings are required for the coupling ports (you
select the Basic Settings:Port Configuration dialog):
See table on
Note: If VLANs are configured, set the coupling and partner coupling
ports' VLAN configuration as follows:
– in the dialog Switching:VLAN:Port Port VLAN ID 1 and „Ingress
Filtering" deactivated
– in the dialog Switching:VLAN:Static VLAN-Membership U
(Untagged)
Note: If you are operating the Ring Manager and two-Switch coupling
functions at the same time, there is the possibility of creating a loop.
