Administratively Enabling the Fabric Plane
This section describes the process for administratively enabling each newly downgradedCisco CRS-1
fabric plane.
Once enabled, the fabric plane status would be "Up".
RP/0/RP0/CPU0:router#admin
RP/0/RP0/CPU0:router(admin)#config
RP/0/RP0/CPU0:router(admin-config)#no controller fabric plane 0 shut
RP/0/RP0/CPU0:router(admin-config)#no controller fabric plane 1 shut
RP/0/RP0/CPU0:router(admin-config)#commit
Verify that each of the eight fabric planes is enabled by executing the show controllers fabric plane all
command:
RP/0/RP0/CPU0:router(admin)#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
Total number of providers for the statistics: 1
