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.



  1. Navigate to Configuration> Stateful Firewall> Destination
  2. Click “Add”
  3. Enter IP version, Destination name and Destination description (optional).

  5. Click “Add” at the bottom
  6. Add the new rule
  7. Click “add” and “Apply.
