The goal of this document is to provide a recommended procedure to deploy SMU for CSCuz14087, CSCva07986 and CSCvb23010. In the event this procedure is not followed, there is a possibility of below set of line cards fail to boot.
Following are the affected Line cards:
- A9K-2x100GE-SE
- A9K-2x100GE-TR
- A9K-1x100GE-SE
- A9K-1x100GE-TR
Note: Additionally only above cards with specific internal revision are affected. More information is below.
There are three versions of above 100Gig Enhanced Ethernet line cards in the field. Though there is no difference in functionality of these line cards, cards with capability value 00, 02 and 03 have different version FPD’s. This is due to the fact that previous version cards (02 and 00) have older version ASIC. These cards have been differentiated using “Capability value” as shown below.
Following command shows card version (See the first Capability field)
RP/0/RP0/CPU0:asr9k-1#admin show diag 0/1/CPU0 eeprom-info | include Cap
Thu Aug 28 22:24:44.460
Capabilities : 00 <== NOT affected by this issue
Capabilities : 10 <== Not important for this issue
RP/0/RP0/CPU0:asr9k-1#admin show diag 0/2/CPU0 eeprom-info | include Cap
Thu Aug 28 22:28:44.460
Capabilities : 02 <== affected by this issue
Capabilities : 10 Not important for this issue
RP/0/RP0/CPU0:MT02#admin show diag 0/3/CPU0 eeprom-info | include Cap
Thu Aug 28 22:34:44.460 UT
Capabilities : 03 <== NOT affected by this issue
Capabilities : 10
Due to the issue documented in CSCuz14087, 02 capability line cards gets loaded with FPD image of 03 capabilities line cards. Hence after FPD upgrade, LC’s with capability 02 may not boot.
This issue is not applicable to “Capability 03” and “capability 00” line cards as correct version FPD is getting loaded.

SMU upgrade procedure for 5.3.2
1. Disable auto FPD upgrade in admin plane. Example output:
RP/1/RSP1/CPU0:asr9k-1#admin config
RP/1/RSP1/CPU0:asr9k-1(admin-config)#no fpd auto-upgrade
RP/1/RSP1/CPU0:asr9k-1(admin-config)#
RP/1/RSP1/CPU0:asr9k-1(admin-config)#commit
2. Install and activate CSCva12633, CSCuz14087 & CSCva07986 SMU’s together. Since all are reload SMU’s, it is important to activate all the SMU’s together to avoid multiple reloads.
RP/1/RSP1/CPU0:asr9k-1#admin install add source <> <SMU’s>
3. Router will be reloaded as above SMU’s are reload
4. After the reload, using below command ensure CSCva12633, CSCuz14087 and CSCva07986 SMU's are active:
RP/1/RSP1/CPU0:asr9k-1#admin show install active summary
5. Check if FPD upgrade is required using below command:
Admin show hw-module fpd location all
6. If FPD upgrade is needed, upgrade all the FPD’s using below command:
Admin upgrade hw-module fpd all location all
7. Once FPD upgrade is successful, reload the router
Note: If if number of LCs/FC/RP's needs to be reloaded within acceptable limit, specific hardware can be reset instead of full router reload.
But in some cases, router reload might be easier from operation point of view.

SMU upgrade procedure for 5.3.3 and 5.2.4
1. Disable auto FPD upgrade in admin plane. Example output:
RP/1/RSP1/CPU0:asr9k-1#admin config
RP/1/RSP1/CPU0:asr9k-1(admin-config)#no fpd auto-upgrade
RP/1/RSP1/CPU0:asr9k-1(admin-config)#
RP/1/RSP1/CPU0:asr9k-1(admin-config)#commit
2. Install and activate CSCva12633, CSCuz14087 & CSCvb23010 (Supercedes CSCva07986) SMU’s together. In 5.3.3 and 5.2.4, CSCva12633 and CSCuz14087 are reload SMU's and CSCvb23010 is a process restart
RP/1/RSP1/CPU0:asr9k-1#admin install add source <> <SMU’s>
3. Router will be reloaded as above SMU’s are reload
4. After the reload, using below command ensure CSCva12633, CSCuz14087 and CSCvb23010 SMU’s are active:
RP/1/RSP1/CPU0:asr9k-1#admin show install active summary
5. Check if FPD upgrade is required using below command:
RP/1/RSP1/CPU0:asr9k-1#Admin show hw-module fpd location all
6. If FPD upgrade is needed, upgrade all the FPD’s using below command:
RP/1/RSP1/CPU0:asr9k-1#Admin upgrade hw-module fpd all location all
7. Once FPD upgrade is successful reload the router.
8. NOTE: If these SMU’s are included in SP(service pack), auto fpd needs to be disabled before installing the SP.

Upgrade from 511,512,513,514,520, 521, 523, 525, 530, 531
1.Disable auto FPD upgrade in admin plane. Example output:
RP/1/RSP1/CPU0:asr9k-1#admin config
RP/1/RSP1/CPU0:asr9k-1(admin-config)#no fpd auto-upgrade
RP/1/RSP1/CPU0:asr9k-1(admin-config)#
RP/1/RSP1/CPU0:asr9k-1(admin-config)#commit
2. Install and activate CSCuz14087. This is a reload and also Mandatory.
RP/1/RSP1/CPU0:asr9k-1#admin install add source <> <SMU’s>
3. After router reload, ensure CSCuz14087 SMU is active on the router:
RP/1/RSP1/CPU0:asr9k-1#admin show install active summary
4. Once above SMU is active, proceed with router upgrade
5.3.4 and higher Releases
534,601,611 and higher doesn’t need any SMU’s. CSCuz14087 is committed in the lineup so no fix is required.
