Verifying the Fabric Plane Status

First, execute the show platform command to verify that all Cisco CRS-3 fabric cards are operational
(i.e. IOS-XR RUN) and all Fabric Planes are UP.
RP/0/RP0/CPU0:router(admin)#show platform

Next, execute the show controllers fabric plane all command to verify that all Fabric Planes are UP:

Note
Before starting the downgrade process, take a snapshot of the traffic flowing through the router and use
it as a benchmark to compare against traffic flow during the downgrade and/or after completing the
downgrade. Since it is a hitless downgrade, there should be zero impact to the traffic flow during the
downgrade and/or after completing the downgrade.
