If the failed switch was a member of a Resilient-Overlay Network (RON),
you can alternatively use
show ron from any other RON member. This
shows the UUID even if the chassis is no longer online. For example, the
following command (run on another switch in the RON) shows the UUID
for a failed chassis, “gffstnA.” Again, the UUID is highlighted in bold text:
bstnA# show ron

Applying the UUID
The initial-boot script has a prompt for the UUID (shown in the example
above). This is where you enter the UUID of the replaced switch. For
example,
...
The UUID should only be entered if this chassis is replacing a failed chassis
and the entered UUID should match the UUID of the failed chassis.
11. Enter the switch's UUID
in the format
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.(default=6df0854c-6af4-11d8-954a-f844c83bc5f3) #
e5d870ae-571e-1352-916b-ef324fbc05a2
...
Important
No two running chassis should ever share the same UUID. Only enter the
UUID in a switch-replacement scenario.
