Enable Backward Compatibility

Enable Backward Compatibility between Catalyst 9800 WLC Devices and Prime Infrastructure 3.9

Cisco Prime Infrastructure 3.9 will support Catalyst 9800 17.x by default, but we have an option to toggle the Catalyst 9800 16.12.x version. Follow the instructions below to toggle the versions.


Important
At any point of time only one version of controller will be active (either 16.12.x or 17.x). By default when you first install Prime Infrastructure 3.9, support for Catalyst 9800 17.4.x will be active.

Procedure to enable Backward Compatibility between Catalyst 9800 Devices and Prime Infrastructure 3.9

Before you begin

Install Cicso Prime Infrastructure 3.9 System patch as mentioned in the System Patch 3.9 section given below.

Ensure you have the administrative previlages right to access nscdiag.

Enable ncsdiag. For more details, see ncs run diag section in the latest Command Reference Guide for Cisco Prime Infrastructure 3.9.

Procedure

Step 1

Change the Catalyst 9800 version using https://<prime ip>/ncsdiag/coralService.html url.

Step 2

In the Coral Service page, click Change coral to change the current Catalyst 9800 version supported by Prime Infrastructure 3.9.

Example: If the Coral Service page shows the Current Coral verison is "Coral 17", once you click Change Coral you will be swapped to "Coral 16".

Step 3

When Prime Infrastructure is in High Availability mode:

  • If you are using Catalyst 9800 17.x and you chose to toggle to Catalyst 9800 16.12.x, you have to wait for the Primary and Secondary Prime Infrastructure instances to synchronize.
  • If you are using Catalyst 9800 16.12.x and you chose to toggle to Catalyst 9800 17.x, you have to delete .coral16 file from /opt/CSCOlumos path in standby Prime Infrastructure manually.

Step 4

When Prime Infrastructure is not on High Availability mode, please skip to Step 5.

Step 5

Restart Prime Infrastructure

Important

 
Restarting the server after toggling the version is essential for the new Catalyst 9800 changes to take effect.

Step 6

Go to the directory /opt/CSCOlumos/coralinstances/coral2/coral/bin to verify if the Catalyst 9800 version has changed by running the ./coral version 1 commands:
