Wired Intelligent Edge (Campus Switching and Routing)

Requirement:

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 

Note:

        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 10.2.10.11

 Optional: Setup Backup Controller IP

 Aruba-Stack-3810M(config)# tunneled-node-server backup-controller-ip 10.2.10.12

 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

Tunneled Node Configuration – Mobility Controller

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

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

   Tunneled Node Port State

   Active Controller IP Address  : 10.2.10.11

   Port   State
