Configuration backup
As a best practice, back up the next-startup configuration file on a device before adding the device to
an IRF fabric as a subordinate device.
A subordinate device's next-startup configuration file might be overwritten if the master and the
subordinate use the same file name for their next-startup configuration files. You can use the backup
file to restore the original configuration after removing the subordinate from the IRF fabric.

Perform this task on each
member device.
Perform this task on one or
multiple member devices to affect
the master election result.
For information about connecting
the crosslink ports, see the user
manual for the enclosure.
Perform this task on each
member device.
When you complete IRF port
binding and activation on all IRF
member devices, the IRF fabric is
formed.
When you log in to the IRF fabric,
you are placed at the master's
CLI, where you complete
subsequent IRF settings and
configure other features for the
member devices as if they were
one device.

MAD mechanisms are
independent of one another. You
can configure multiple MAD
mechanisms for an IRF fabric.
