Hello,
I would appreciate, if someone could please confirm my understanding:
The CPLD version is embedded in the uploaded image*, it is not available as individually download from the Cisco Download site. However, when upgrading the switch, the CPLD version still needs to be upgraded manually following the steps below:
*CPLD comes with the images as listed below:
ReleaseROMMON Version (C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y)CPLD Version (C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y)ROMMON Version (C9400X-SUP-2, C9400X-SUP-2XL)CPLD Version (C9400X-SUP-2, C9400X-SUP-2XL)

- Procedure to CPLD upgrade version
Step 1 | Upgrade the CPLD Version of the standby supervisor module Enter the following commands on the active supervisor: - Device# configure terminal
- Device(config)# service internal
- Device(config)# exit
- Device# upgrade hw-programmable cpld filename bootflash: rp [ standby | active ]
The standby supervisor module reloads automatically and the upgrade occurs in ROMMON. During the upgrade, the supervisor module automatically power cycles and remains inactive for approximately 5 minutes. Wait until the standby supervisor module boots up and the SSO has formed (HOT) before you proceed to the next step; this takes approximately 17 minutes. |
Step 2 | Perform a switch over - Device# redundancy force-switchover
This causes the standby supervisor (on which you have completed the CPLD upgrade in Step 1) to become the active supervisor module |
Step 3 | Upgrade the CPLD Version of the new standby supervisor module Repeat Step 1 and all its substeps. NOTE: Do not operate an HA system with mismatched FPGA versions. FPGA version should be upgraded on both the supervisors one at a time. When performing the CPLD version upgrade as shown, the show platform command can be used to confirm the CPLD version after the upgrade. This command output shows the CPLD version on all modules. However, the CPLD upgrade only applies to the supervisors, not the line cards. The line cards CPLD version is a cosmetic display. After the upgrade is completed in a high availability setup, the supervisors will be upgraded, but the line cards will still show the old CPLD version. The version mismatch between the supervisors and line cards is expected until a chassis reload. |
