Configuring MRP

Adding an MRP ring to a vlan
NOTE
If you plan to use a topology group make sure you configure MRP on the topology group’s master
vlan.
To add a MRP ring to a vlan, enter commands such as the following.
Brocade(config)# vlan 2
Brocade(config-vlan-2)# metro-ring 1
Brocade(config-vlan-2-mrp-1)# name CustomerA
Brocade(config-vlan-2-mrp-1)# ring-interface ethernet 1/1 ethernet 1/2
Brocade(config-vlan-2-mrp-1)# enable
These commands configure an MRP ring in vlan 2 with a ring ID of 1, a ring name of Customer A. If
the node is the master then the following command is used to specify the node as the master for
the ring.
Brocade
(config-vlan-2-mrp-1)# master
The ring interfaces are 1/1 and 1/2. The first interface listed will be allocated as the primary
interface and the second will be allocated as the secondary interface. The primary interface
initiates RHPs. The ring takes effect in vlan 2.
Syntax: [no] metro-ring ring-id
The ring-id parameter specifies the ring ID 1 – 255. Configure the same ring ID on each of the
nodes in the ring.
Syntax: [no] name string
The string parameter specifies a name for the ring. The name is optional, but it can be up to 20
characters long and can include blank spaces. If you use a name that has blank spaces, enclose
the name in double quotation marks (for example: “Customer A”).
Syntax: [no] master
Configures this node as the master node for the ring. Enter this command only on one node in the
ring. The node is a member (non-master) node by default.
Syntax: [no] ring-interface ethernet primary-if ethernet secondary-if
The ethernet primary-if parameter specifies the primary interface. On the master node, the primary
interface originates RHPs. Ring control traffic will flow out of this interface by default. On member
nodes the order in which you enter the interfaces does not matter as the secondary interface is
determined by the receipt of RHP’s from the master meaning the other interface defined in config
becomes the primary. Once the ring is enabled the configuration entries on a member switch will
reflect the ring direction no matter what order they are originally entered.
The ethernet secondary-if parameter specifies the secondary interface.
NOTE
The Brocade NetIron CES and Brocade NetIron CER devices do not support selection of a secondary
interface based on reception of RHPs. As a result, the primary and secondary interfaces must be
configured correctly.
Syntax: [no] enable
The enable command enables the ring.
