Performing incompatible ISSU upgrade
CAUTION:
To upgrade system software of the IRF fabric through ISSU when the new and current system software
image versions are incompatible, make sure that the multi-active detection (MAD) function has been
configured for the IRF fabric. Otherwise, duplicate IRF fabrics will coexist after the new master (the slave
switch specified with the
issu load
command) is rebooted, causing network faults.
# Upgrade the specified slave switch (the new master after the upgrade), which is slave switch 2 in this
example.
