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 switch configuration of the IE 3100 without the need for direct switch "console port" level knowledge and access.
Note: The IP Network Wizard Tool does not support non-standard configuration of the IE 3100 switches, or the configuration of the IE 3200, IE 3300, and IE 3400 switches. Manual configuration of the MRP switch is required. Use of the BAS IT Network Questionnaire is recommended to determine site specific configuration requirements by the customer.

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 IE 2000 IOS CLI command

Cisco IE 3100 IOS XE CLI command

1

Enable the MPR ring manager right-to use license.

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

Active by default in IOS XE.

2

Enter global configuration mode.

Switch# configure terminal

3

Disable PROFINET MRP.

Switch(config)# no profinet mrp

Active by default in IOS XE.

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

Switch(config-mrp)# mode auto-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

Switch(config)# interface GigabitEthernet1/1

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

Switch(config)# interface GigabitEthernet1/2

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
