UM Config GRS
Release 8.0 09/2019
The following steps contain additional settings for subring configuration:

To help prevent loops during configuration, deactivate the Subring Manager function on the
main ring and subring devices. After you completely configure every device participating in the
main ring and subrings activate the global
Sub Ring
function and Subring Managers.

Disable the RSTP function on the MRP ring ports used in the subring.

Verify that the
Link Aggregation
function is inactive on ports participating in the main ring and
subring.

Specify a different VLAN membership for the main ring ports and subring ports although the
main ring is using the MRP protocol. For example, use VLAN ID 1 for the main ring and the
redundant link, then use VLAN ID 2 for the subring.
– For the devices participating in the main ring for example, open the
Switching > VLAN >
Configuration dialog. Create VLAN 1 in the static VLAN table. Tag the main ring ports for
membership in VLAN 1 by selecting T from the drop-down list of the appropriate port
columns.
– For the devices participating in the subring use the step above and add the ports to VLAN 2
in the static VLAN table.

Activate the
MRP
function for the main ring and subring devices.
– In the
Switching > L2-Redundancy > MRP
dialog, configure the 2 ring ports participating in the
main ring on the main ring devices.
– For the devices participating in the subring use the step above and configure the 2 ring ports
participating in the subring on the subring devices.
– Assign the same MRP domain ID to the main ring and subring devices. When you only use
Hirschmann devices, the default values suffice for the MRP domain ID.
Note: The
MRP domain
is a sequence of 16 numbers in the range from 0 to 255 . The default value
is 255 . 255 . 255 . 255 . 255 . 255 . 255 . 255 . 255 . 255 . 255 . 255 . 255 .
255 . 255 . 255 . A
MRP domain
consisting entirely of zeroes is invalid.
The
Sub Ring
dialog lets you change the MRP domain ID. Otherwise open the Command Line
Interface and proceed as follows:
12.8.3 Subring example configuration
Note: Help avoid loops during configuration. Configure every device of the subring individually.
Before you activate the redundant link, completely configure every subring device.
Proceed as follows to configure the 2 Subring Managers in the example:
enable
Change to the Privileged EXEC mode.
configure
Change to the Configuration mode.
mrp domain delete
Deletes the current MRP domain.
mrp domain add domain-id
0.0.1.1.2.2.3.4.4.111.
222.123.0.0.66.99
Creates a new MRP domain with the specified
MRP domain ID. Any subsequent MRP domain
changes apply to this domain ID.

Open the
Switching > L2-Redundancy > Sub Ring
dialog.

To add a table entry, click the button.

In the Port column, select the port that couples the device to the subring.
Use port
1/3
for this example.
For coupling, use one of the available ports with the exception of the ports which are
already connected to the main ring.
