How to Migrate to a Cisco CRS-3 Carrier Routing System (4-Slot)
When the boot process completes the node-state will be IOS-XR RUN.

Administratively Enabling the Fabric Plane
This section describes the process for administratively enabling each new Cisco CRS-3 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
Plane Admin Oper up->dn up->mcast
Id State State counter counter
---------------------------------------------
0 UP UP 2 2
1 UP UP 2 2
2 UP UP 0 0
3 UP UP 0 0
4 UP UP 0 0
5 UP UP 0 0
6 UP UP 0 0
7 UP UP 0 0
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 Migrated Cisco CRS-3 Node
To ascertain that traffic is flowing on the CRS-3 node please run the following command on both the
planes that have been migrated. Run it a few times to ensure that the counters are incrementing. The lost
or error counters should not be incrementing.
The same command should also be applied on the legacy nodes (not yet migrated) to make sure there is
no traffic lost or traffic with errored cells.
