Planning the IRF fabric setup

Consider the following items when you plan an IRF fabric:
• Hardware compatibility and restrictions.
IRF fabric size.
•
Master device.
•
IRF physical interfaces.
•
Member ID and priority assignment scheme.
•
• Fabric topology and cabling scheme.
For more information about hardware and cabling, see the installation guide for the device.
Preconfiguring IRF member devices in standalone
mode
Perform the preconfiguration tasks on every IRF member device. These settings take effect on each
member device after their operating mode changes to IRF.

Assigning a member ID to each IRF member device

By default, a device operates in standalone mode without an IRF member ID. You must assign it a unique
IRF member ID before changing its operating mode to IRF.
The member ID assigned to a device is saved in both active and standby MPUs of the device. The standby
MPU might store a different member ID than the active MPU after an MPU replacement. For consistency,
the system automatically updates the member ID in the active MPU to the standby MPU when the
difference is detected.
To set a member ID for the device in standalone mode:

Remarks
Adding physical interfaces to an IRF
port is required if you did not
preconfigure IRF port bindings.
CAUTION:
Changing member IDs in an IRF
fabric can void member ID-related
configuration and cause
unexpected problems. Make sure
you understand the impact on your
live network before you change
member IDs.
