Verify that each of the eight fabric planes is enabled by executing the show controllers fabric plane all

Each plane transitions from UP -> MCAST_DOWN -> DOWN -> MCAST_DOWN -> UP. Thus each
plane will cycle through up->dn twice. This is why the up->dn counter shows 2. Similarly each plane
will cycle through mcast_dn->up twice as well and the mcast_dn->up counter shows 2.

Verifying Traffic Statistics on the Newly Downgraded Cisco CRS-1 Node

To ascertain that traffic is flowing on the downgraded Cisco CRS-1 fabric node please run the following
show controllers fabric plane 0 statistics detail command on both the planes that have been
downgraded. Run it a few times to ensure that the counters are incrementing. The lost or error counters
should not be incrementing.
The same show controllers fabric plane 0 statistics detail command should also be applied on the
Cisco CRS-3 nodes that have not yet been downgraded to make sure there is no traffic lost or traffic with
errored cells.
RP/0/RP0/CPU0:router(admin)#show controllers fabric plane 0 statistics detail
