====== Vxlan config example ======
The following recipe may configurs a vxlan tunnel between a linux host and an Aruba switch.
===== On Ubuntu linux host =====
  * ([[ https://joejulian.name/post/how-to-configure-linux-vxlans-with-multiple-unicast-endpoints/| Example source ]])
  * Create vxlan device ''vxlan0'' with vxlan network identifier ''42'', remote tunnel host ip and (default) port 4789: 
sudo ip link add vxlan0 type vxlan id 42 dev eth1 remote 158.38.153.170 dstport 4789
  * Assign ip vtep address and turn up interface: 
ip addr add 192.168.0.1/24 dev vxlan0  
ip link set up dev vxlan0
===== On Aruba 2930F switch =====
  * Prerequisits
    * Need vlan with static IP, i.e. vlan 2 for port 2 with IP 
(config)# interface 2 untagged vlan 2
(config)# vlan 2 ip address 158.38.153.141
    
    * (The IP set above cannot be on a the same subnet as other IP's set in the switch.)
  * Enter configuration and enable vxlan tunnels: 
# configure
(config)# vxlan enable
  * Create virtual network an associate network id 42 and Vlan 2 
(config)# virtual-network 42 2 "Vxlan-net1"
