Fault fltCoopDomCoopDomCitizenVersionLower
                

Rule ID:1662

Explanation:
This fault occurs when the version of the Council Of Oracles Protocol (COOP) running on a leaf (citizen node) is determined by the spine (oracle node) to be lower than what is currently supported. No impact to connectivity should be seen due to running at lower version. However, failure to upgrade to the fabric node firmware on the leaf that contains highest supported version of coop may impact coop performance or coop may not operate with supported functionalities introduced in the higher coop version.

Recommended Action:
To recover from this fault, try the following actions

1. Verify there is no leaf (citizen node) with a lower coop version than highest supported version running in the fabric. To verify the leaf with lower version:
   • Use the GUI to examine the maxVersion value under Fabric > Inventory > Pod > Leaf > Protocols > COOP > [domain-name] ; or
   • Use REST API to examine the maxVersion value from https://[leaf-ip]/api/mo/sys/coop/inst/dom-[domain-name].xml; or
   • Use CLI to examine the maxVersion value in file /mit/sys/coop/inst/dom-[domain-name]
2. Upgrade the fabric node software on the leaf in question to a version that has the highest supported coop version running in the fabric. You can examine other leafs to determine what switch firmware version to upgrade to.
3. If the above actions did not resolve the issue, generate the show tech-support file and contact Cisco TAC.
