Step 1 |
admin
Example:
RP/0/RP1/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 |
show platform rack number/**/*
Example:
RP/0/RP1/CPU0:router(admin)# show platform 1/**/*
|
Displays the status of all LCC modules in the specified rack.
-
Replace rack
with the rack number of the LCC to examine.
-
Repeat this command for all LCCs.
-
The state for all modules should be IOS-XR RUN.
-
It can take a few minutes for all LCC modules to start.
Note
|
The LCC module status appears only when the show platform command is executed in administration EXEC mode. |
|
Step 3 | configure
Example:
RP/0/RP1/CPU0:router(admin)#configure
|
Places the router in administration configuration mode.
|
Step 4 | do show controllers fabric plane all
Example:
RP/0/RP1/CPU0:router(admin-config)# do show controllers fabric plane all
|
Displays the administrative and operational status of all eight fabric planes.
-
The do command prefix allows the EXEC mode show command to execute in administration configuration mode.
Caution
|
To prevent service interruption, do not continue until the administrative and operational status for all eight planes is UP.
|
|
Step 5 |
controllers fabric plane planeNumber
shutdown
Example:
RP/0/RP1/CPU0:router(admin-config)# controllers fabric plane 0 shutdown
|
Modifies the target configuration to shut down the specified plane number.
-
Replace the planeNumber
parameter with the number of the plane you want to shut down.
-
The admin/operational state will be DOWN/DOWN.
|
Step 6 | commit
Example:
RP/0/RP1/CPU0:router(admin-config)# commit
|
Commits the target configuration to the router running configuration.
-
This step shuts down the plane identified in the previous step.
|
Step 7 | hw-module power disable location 0/smslotNumber
/sp
Example:
RP/0/RP1/CPU0:router(admin-config)# hw-module power disable location 0/sm0/sp
|
Disables the power-on feature on a specific fabric card.
|
Step 8 | commit
Example:
RP/0/RP1/CPU0:router(admin-config)# commit
|
Commits the target configuration to the router running configuration.
-
This step shuts down the plane identified in the previous step.
|
Step 9 | show platform 0/smslotNumber/sp
Example:
RP/0/RP1/CPU0:router(admin)# show platform 0/sm0/sp
|
Displays the status of the Rack 0 fabric slot specified by slotNumber
. Verify that the card is in the UNPOWERED state.
Note
|
The fabric card status appears only when the show platform command is executed in administration EXEC mode. |
|
Step 10 |
In Rack 0, remove the FC/S card (CRS-8-FC/S or CRS-8-FC140/S) for the plane that was shut down in Step 5
.
|
Creates room for the FC-140G/M card that is required for CRS-3 Back-to-Back System operation.
|
Step 11 |
In Rack 0, insert the FC-140G/M card for the plane that was shut down in Step 5
.
|
Provides the hardware required for communication with the LCC.
|
Step 12 | no hw-module power disable location 0/smslotNumber
/sp
Example:
RP/0/RP1/CPU0:router(admin-config)# no hw-module power disable location 0/sm0/sp
Example:
|
Re-enables the power-on feature on a specific fabric card.
|
Step 13 | commit
Example:
RP/0/RP1/CPU0:router(admin-config)# commit
|
Commits the target configuration to the router running configuration.
|
Step 14 | do show platform 0/smslotNumber/sp
Example:
RP/0/RP1/CPU0:router(admin)# show platform 0/sm0/sp
|
Displays the status of the Rack 0 fabric slot specified by slotNumber
. Verify that the card is in the IOS XR RUN state.
Note
|
The fabric card status appears only when the show platform command is executed in administration EXEC mode. |
|
Step 15 | do show log | inc OPER_UP
Example:
RP/0/RP0/CPU0:b2b(admin-config)#do show logging | inc OPER_UP
|
Displays the status of the fabric asic. The desired output will show two fabric asics in service for the plane that you just upgraded. If you do not see both asics in the UP state, do not continue. Output appears similar to the following:
-
SP/0/SM3/SP:May 19 17:51:32.599 : sfe_drvr[131]: %FABRIC-FABRIC_DRVR-6-ASIC_INITIALIZED : Notify FSDB that superstar/0/SM3/SP/0 is OPER_UP.
-
SP/0/SM3/SP:May 19 17:51:32.600 : sfe_drvr[131]: %FABRIC-FABRIC_DRVR-6-ASIC_INITIALIZED : Notify FSDB that superstar/0/SM3/SP/1 is OPER_UP
|
Step 16 | controllers fabric plane planeNumber shutdown data
Example:
RP/0/RP0/CPU0:b2b(admin-config)#controllers fabric plane 3 shutdown data
|
Modifies the target configuration to bring up the control part of the specified fabric plane.
The suggested admin/operational state of the plane in this state would be DATA_DN/UP, respectively.
|
Step 17 | do show controllers fabric plane planeNumber detail
Example:
RP/0/RP1/CPU0:router(admin-config)# do show controllers fabric plane 0 detail
|
Displays the status of the plane specified by planeNumber
.
-
Verify that the admin/operational state is DATA_DN/UP.
-
Verify that a capital “D” appears in the Down Flags column.
-
Wait for the plane to come up before you continue.
|
Step 18 |
no controllers fabric plane planeNumber shutdown
Example:
RP/0/RP1/CPU0:router(admin-config)# no controllers fabric plane 0 shutdown
|
Modifies the target configuration to bring up the specified fabric plane.
-
Verify that the admin/operational state is UP/UP.
-
This step brings up the previously shutdown plane, which is now configured to use the Back-to-Back LCC.
|
Step 19 | end
Example:
RP/0/RP1/CPU0:router(admin-config)# end
|
Changes the mode from administration configuration mode to administration EXEC mode.
|
Step 20 |
Repeat Step 2
through Step 19
for each fabric plane.
|
|
Step 21 |
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 operational and the status is UP/UP.
-
The plane you just migrated should show a counter increment of 1 in both the up->dn counter and the up->mcast counter.
