Multiple Rings
 Other settings:
– Define a different VLAN membership for the Primary Ring and the
Sub-Ring even if the basis ring is using the MRP protocol, e.g. VLAN
ID 1 for the Primary Ring and VLAN ID 2 for the Sub-Ring.
– For all ring ports in the Sub-Ring, select this VLAN ID and the VLAN
membership Tagged (T) in the static VLAN table.
– Switch the MRP-Ring function on for all devices.
– In the Ring Redundancy dialog, under MRP-Ring, configure for all
devices the two ring ports used in the Sub-Ring.
– Switch the Ring Manager function off for all devices.
– Do not configure link aggregation.
– Switch RSTP off for the MRP Ring ports used in the Sub-Ring.
– Assign the same MRP domain ID to all devices. If you are only using
Hirschmann Automation and Control GmbH devices, you do not have
to change the default value for the MRP domain ID.
Note: The MRP domain ID is a sequence of 16 numbers (range 0 to 255).
The default domain (in the CLI: "default-domain") is the MRP domain ID of
255 255 255 255 255 255 255 255 255 255 255 255 255 255 255 255. A MRP
domain ID consisting entirely of zeroes is invalid.
If you need to adjust the MRP domain ID, open the Command Line Interface
(CLI) and proceed as follows:
enable
configure
mrp delete-domain
current-domain
MRP current domain deleted:
Domain ID:
255.255.255.255.255.255.255.255.255.255.255.255.255.255.255.255
(Default MRP domain)

Switch to the privileged EXEC mode.
Switch to the Configuration mode.
Deletes the current MRP domain. If no MRP
domain exists, the device outputs an error
message.
