IxLoad How to create an ARP broadcast storm

   IxLoad was not design to test L2 features ( as ARP)  but in case you do not have available other tools as IxNetwork or IxExplorer  there are some ways on  which you create an ARP  storm.

Scenario:
Let's  say you need to have 1000 ARP  request  sent to your Gateway IP address

Setup:
Create one IP Range having 1000 IP address and set the GW as your DUT.
DUT IP=1.0.0.1
Ixia Port IP= 1.0.0.2+1000/22

Configuration:
1. Create one IP range with 1000 clients

2. Click on IP  plugin on the stack and then  click on Plugin settings in Main ribbon.
     Enable  Gateway ARP for each IP Address

3. Apply the configuration in order to generate the ARP storm,  you do not need to run the configuration.

IxLoad How to configure Static ARP

  There are situation on which  the Gateway  IP address  is configured on a DUT which does not reply  to ARP  request. For this particular cases you need to create a static ARP entry for the gateway on IxLoad.

Setup:
Let's consider the following setup:
Client IP address is 1.1.1.1
Gateway  IP address is 1.1.1.254 and Gateway MAC address is aa:bb:cc:00:00:00
***GW does not reply to ARP

Configuration:
In order to accomodate this setup, you will need to add a Static ARP plugin which  on which you will define the MAC address associated with the Gateway IP address  as in the  images bellow.

 1. Righ click on the IP plugin and chose Add above Static ARP

2.  Set the proper (MAC, IP ) association on the Static ARP plugin

**If you are not able to  add a plugin,  make sure that the configuration is not applied on the ports . Press the button Release Config in Main ribbon and then try to perform the steps again.
