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 switch installation guide.
Assigning a member ID to each IRF member
device
CAUTION:
In an IRF fabric, changing IRF member IDs might cause undesirable configuration changes and
even data loss. Before you do that, back up the configuration and make sure you fully understand
the impact on your network. For example, all member devices in an IRF fabric are the same model.
If you swapped the IDs of any two members, their interface settings would also be swapped.
To create an IRF fabric, you must assign a unique IRF member ID to each member device.
To prevent any undesirable configuration change or data loss, avoid changing member IDs after the
IRF fabric is formed.
The new member ID takes effect at a 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.
