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.
Generic Layout
Solution:Tunneled Node Status – Aruba Mobility Controller
Note:
Tunnel is automatically created when Tunneled-Node is enabled on switch interface.
Configuration: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
VerificationStep 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
