Sub-Ring Example - Hirschmann RS20 User Manual

Multiple Rings
Note: Sub-Rings use MRP. You can couple Sub-Rings to existing primary
rings with the HIPER-Ring protocol, the Fast HIPER-Ring protocol and MRP.
If you couple a Sub-Ring to a primary ring under MRP, configure both rings
in different VLANs. You configure
 either the Sub-Ring Managers' Sub-Ring ports and the devices of the
Sub-Ring in a separate VLAN. Here multiple Sub-Rings can use the same
VLAN.
 or the devices of the primary ring including the Sub-Ring Managers'
primary ring ports in a separate VLAN. This reduces the configuration
effort when coupling multiple Sub-Rings to a primary ring.

Sub-Ring example

You want to couple a new network segment with 3 devices to an existing
redundant ring with the HIPER-Ring protocol. If you couple the network at
both ends instead of only one end, this provides increased availability with
the corresponding configuration.
The new network segment is connected as a Sub-Ring. The connection is
made to existing devices of the basis ring with the following types:
– RSR20/RSR30
– MACH 1000
– MACH 1040
– MACH 4000
– PowerMICE
Configure these devices as Sub-Ring Managers.
