Issue :

• While preparing SharePoint server, we have missed the configuring Distributed Cache Service on WFEs
• Distributed cache service is not registered
• We were not able to see the “Distributed Cache service” listed on the “Service on Server”page in Central Administration

Solution : We need to Add a WFEs to the cache cluster and starting the Distributed Cache service by using SharePoint Management Shell

• Start the SharePoint Management Shell on WFE which we need to add to cache-cluster
• Execute the following CMDLET

Add-SPDistributedCacheServiceInstance

What is Distributed Cache Service :

• Distributed Cache service provides caching functionality for following features
  • Authentication
  • Newsfeeds
  • OneNote client access
  • Security Trimming
  • Page load performance
