Accessing The Irf Fabric; Configuring Irf Member Devices In Irf Mode; Assigning An Irf Domain Id To The Irf Fabric; Changing The Member Id Of A Device - HP FlexFabric 12500 Series Configuration Manual

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 global active MPU. All settings you made are propagated automatically to the IRF members.
When you log in to an IRF fabric, you are placed at the CLI of the global active MPU, regardless of at
which member device you are logged in.
You can use the following methods to access an IRF fabric:
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 by using
•
methods including Telnet, Web, and SNMP.
For more information, see the chapter on login in Fundamentals Configuration Guide.

Configuring IRF member devices in IRF mode

After you access the global active MPU's CLI, you can perform the tasks in this section or configure
features in all other configuration guides for the device.

Assigning an IRF domain ID to the IRF fabric

This task is required for running LACP MAD, ARP MAD, or ND 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.
To assign a domain ID to an IRF fabric:
Step
1. Enter system view.
2. Assign a domain ID to the
IRF fabric.

Changing the member ID of a device

CAUTION:
In IRF mode, an IRF member ID change can invalidate member ID-related settings and cause data loss. Be
sure you fully understand its impact on your live network.
The new member ID takes effect at reboot. After the device reboots, the settings on all member ID related
physical resources (including common physical network ports) are removed, regardless of whether you
have saved the configuration.
To change the member ID of a member device:
Command
system-view
irf domain domain-id
23
Remarks
N/A
By default, the domain ID of an IRF fabric is 0.
