Accessing The Irf Fabric; Configuring Irf Member Devices In Irf Mode; Assigning An Irf Domain Id To The Irf Fabric - HP 12500 SERIES Configuration Manual

Step
1. Enter system view.
2. Set the operating mode to
IRF mode.
After you change the operating mode, the device automatically reboots to validate the change.
During the reboot, you may choose to have the system automatically convert the startup
configuration file to prevent some slot- or interface-related configurations from becoming invalid.
For example, the system can convert the slot slot-number parameter set in standalone mode to the
chassis chassis-number slot slot-number parameter in IRF mode, and add the chassis ID in an
interface number.
To restore the standalone mode, use the undo chassis convert mode command.
TIP:
IRF generates packets on a device in IRF mode, even if the device does not form an IRF fabric with
any other device. To avoid IRF protocol packets consuming system resources, set a device to
operate in standalone mode after removing it from an IRF fabric.

Accessing the IRF fabric

The IRF fabric appears as one device after it is formed. You configure and manage all IRF members
at the CLI of the master MPU. All settings you made are automatically propagated to the IRF
members.
When you log in to an IRF fabric, you are placed at the CLI of the master MPU, regardless of at
which member device you are logged in.
You can access an IRF fabric in one of the following ways:
Local login—Log in through the console or AUX port of a member device.
•
Remote login—Remotely log in at a Layer 3 Ethernet interface on any member device through
•
Telnet, Web, or SNMP.
For more information, see the login chapter in Fundamentals Configuration Guide.

Configuring IRF member devices in IRF mode

After you access the master MPU's CLI, you can perform the tasks in this section or configure
features in other configuration guides for the IRF fabric.

Assigning an IRF domain ID to the IRF fabric

This task is required for running LACP MAD and ARP MAD between two IRF fabrics. For BFD MAD,
this task is optional.
One IRF fabric forms one IRF domain. IRF domain IDs prevent IRF fabrics from interfering with one
another.
In Figure 13, Device A and Device B form IRF fabric 1, and Device C and Device D form IRF fabric 2.
These fabrics have LACP MAD links between them. When a member device in one IRF fabric
