Why do we need “alias” or “netdestination” and how to configure it on Aruba controller?

This article explains the use of “netdestination” or “alias” and steps to configure it on the Aruba controller

 

“Alias” or “Netdestination” is created as an alias to a specific host, network or to club together a set of hosts/networks. While using this option, you need to configure the IP address of the host/network.

This can be useful if we need to allow/disallow a specific set of hosts/network then we need not permit or deny each host/network separately. We can instead create a netdestination containing those hosts/networks and allow or disallow access.

 

 

Environment : This article applies to all the controller models and AOS versions.
