While other switch vendors may support MRP, Cisco has optimized their MRP ring manager to support large rings of Johnson Controls IP controllers. Cisco is therefore Johnson Control’s switch vendor of choice when deploying MRP rings.

Note: The IP Network Wizard tool has been designed to support the network design and enable switch configuration without the need for direct switch "console port" level knowledge and access.

The following steps are required to configure an MRP ring on a Cisco Industrial Ethernet (IE) managed switch.

Table 1. Configuring Media Redundancy Protocol (MRP) Rings on a Cisco Managed Switch

Configuration Step

Cisco IOS CLI Command

1

Enable the MPR ring manager right-to use license.

Switch# license right-to-use activate mrp manager acceptEULA

2

Enter global configuration mode.

Switch# configure terminal

3

Disable PROFINET MRP.

Switch(config)# no profinet mrp

4

Create an MPR ring (1-3). In this example, MPR ring 1 is created.

Switch(config)# mrp ring 1

5

Configure the MRP manager mode.

Switch(config-mrp)# mode manager

6

Configure the domain ID of the MRP ring. In this example the 32 hexadecimal digit domain ID of MPR ring 1 is set to 1 followed by 31 Fs.

Switch(config-mrp)# domain-name 1FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

7

Configure the VLAN of the MRP ring. In this example, the MRP ring is in VLAN 10.

Switch(config-mrp)# vlan-id 10

8

Configure the recovery profile of the MRP ring. In this example, the maximum recovery time is set to 200 msec.

Switch(config-mrp)# profile 200

9

Exit configuration mode for the MRP ring.

Switch(config-mrp)# exit

10

Configure the switch port that will serve as the first ring port for the MRP ring. In this example, switch ports 1 and 2 will be configured as the ring ports for MRP ring 1.

Switch(config)# interface fastethernet 1/1

11

Configure the switch port as an access port.

Switch(config-if)# switchport mode access

12

Associate the switch port with the MPR ring.

Switch(config-if)# mrp ring 1

13

Exit configuration mode for the switch port.

Switch(config-if)# exit

14

Configure the switch port that will serve as the second ring port for the MRP ring.

Switch(config)# interface fastethernet 1/2

15

Configure the switch port as an access port.

Switch(config-if)# switchport mode access

16

Associate the switch port with the MPR ring.

Switch(config-if)# mrp ring 1

17 Exit global configuration mode.

Switch(config-if)# end
