How to Migrate to a Cisco CRS-3 Carrier Routing System (4-Slot)
DETAILED STEPS
What to Do Next
Next we disable power to the Fabric node, and verify that node is moved to Unpowered state.
Disabling Power to the CRS-1 Fabric Card
Prerequisites
Software Requirements
• Cisco IOS XR Software Release 4.0.0.T or later release (Cisco IOS XR Software Release 4.0.2 for
multishelf nodes)
• ROMMON 1.54 or later version (for Route Processor [RP])
Command or Action Purpose
Step 1
admin
Example:
RP/0/RP0/CPU0:router#admin
Places the router in administration EXEC mode.
• All commands listed in this procedure should be
entered on the pre-existing single-chassis system.
Step 2
configure
Example:
RP/0/RP1/CPU0:router(admin)#configure
Places the router in administration configuration mode.
Step 3
controller fabric plane 0 shut
Example:
RP/0/RP1/CPU0:router(admin-config)# controller
fabric plane 0 shut
Shuts down the fabric plane in the system.
• In a 4-slot CRS-1 router, we have four fabric nodes, or
Fabric Controller cards, numbered 0/SM0/SP to
0/SM3/SP. Each Fabric Controller card has one plane.
So for a 4-slot CRS-1 to CRS-3 migration we will be
migrating one plane at a time for all four planes.
Step 4
commit
Example:
RP/0/RP1/CPU0:router(admin-config)# commit
Commits the target configuration to the router running
configuration.
• This step brings up the previously shutdown plane,
which is now configured to use the CRS-3 fabric card.
Step 5
end
Example:
RP/0/RP1/CPU0:router(admin-config)# end
Changes the mode from administration configuration mode
to administration EXEC mode.
Step 6
Repeat Step 3 through Step 5 for each fabric plane.
Step 7
show controllers fabric plane all
Example:
RP/0/RP1/CPU0:router(admin)# show controllers
fabric plane all
Displays the administrative and operational status of all
eight fabric planes.
• Verify that all fabric planes are administrative state
down.
