How to do Tunneled Node Configuration on Aruba OS switches.


Supported Model of switches ?


•5400R switch series with v2 and v3 modules

•3810 switch series

•3800 switch series

•2930F switch series

•2920 switch series


What is Tunneled Node?

•Extends the AP-controller tunneling scheme to the access switches.

•A single GRE tunnel transports all traffic to/from “tunneled” interfaces




•Traffic from other interfaces is forwarded normally by the switch

•Management and control traffic is NOT tunneled.

Tunneled Node Status – Aruba Mobility Controller 



        Tunnel is automatically created when Tunneled-Node is enabled on switch interface.




Tunneled Node Configuration – Switch Configuration Steps


Step 1: Setup Tunneled-Node-Server IP address (Aruba Mobility Controller)

  Aruba-Stack-3810M(config)# tunneled-node-server controller-ip


 Optional: Setup Backup Controller IP

 Aruba-Stack-3810M(config)# tunneled-node-server backup-controller-ip

 Optional: Set Tunneled-Node Keepalive timer – Set time interval between keepalive messages (Default = 8)

Aruba-Stack-3810M(config)# tunneled-node-server keepalive interval

 <1-8>                                         Configure the time interval between two successive

                                                 keepalive messages sent to the controller.


Step 2: Enable Tunneled-Node on interface


Aruba-Stack-3810M (config)# interface 1/23

Aruba-Stack-3810M (eth-1/23)# tunneled-node-server

Step 3: Check to see if Tunneled-Node is complete


  Aruba-Stack-3810M(config)# show tunneled-node-server state
