Example 1: MRP Manager Re-Config (Web UI)
This application example shows the MRP Manager reconfiguring the traffic path based on the client state.
Sample Setup
: This setup includes one device with MRP enabled and has an admin role set as Manager and
three clients connected in a ring topology. See the MRP Sample Setup diagram below.
Procedure
:
1.
Disable any other Ring technologies and disable Spanning-tree at Configuration > Spanning Tree > CIST Port.
2.
For the device acting as MRM click 'Add New Domain' button to configure the MRP instance in the 'Media
Redundancy Protocol Configuration' page.
3.
Assign the first ring port under 'Primary' and the second ring port under 'Secondary'.
4.
Set the Administrative Role to 'Manager' under 'Adm. Role'. Assign any VLAN ID from 2-4094.
5.
Set the instance to 'enable'.
6.
Go to the 'Ring Domain Configuration (Manager Role)' page and set a Domain name.
7.
Tick the Default box for UUID.
8.
Select the Primary and Secondary Port IDs.
9.
Enable 'Check Media Redundancy'.
10.
Leave other settings as default.
11.
For the devices acting as MRCs in the 'Ring Domain Configuration (Client Role)' page assign the first Primary
and Secondary Port IDs for the ring ports.
12.
Enter the same VLAN ID as in step 4 above.
13.
Link Down Interval should be 20ms. Link Up Interval should be 20ms. Link change count should be 4.
14.
'BLOCKED State Supported' must be enabled. By default, one ring port will be disabled for loop-free
communication.
15.
Configure ring ports to Hybrid mode on the VLAN Configuration page. Assign the VLAN ID as configured in
step 4.
16.
Send bi-directional traffic tagged with the VLAN ID set in step 4 above.
17.
Create a failure on any one of the client ring ports by disconnecting the cable. The MRM should reconfigure
the path within 200<500ms. The Redundancy Manager will send test frames marked with a unique MAC
with OUI of 00-15-4E and forwarded by the MRCs to the opposite ring ports per the interval specified.
The disabled ring port should now be enabled, creating a new loop-free topology.
18.
There should be no traffic loss after path reconfiguration.
