IxNetwork Traffic : How to Configure Incremental Raw Traffic

In  case you need to send IP traffic from a  bunch  of source addresses  to   other bunch of destination address you have to options.

Option 1: configure IP Interfaces and use them to create  IPv4 Traffic Item

 This is useful when you   need to   add different other protocol on those IP addresses: let’s say that when you need  to send traffic from 1.1.0.1 and in the same time 1.1.0.1 should be a simulated OSPF Router

 Option 2: create directly Raw Traffic Item   between 2 ports and add IPv4 on payload .

This is useful if your purpose is just to send traffic. Take in consideration that you should  know the value of the 1^st Hop MAC Address  ( if  the traffic will pass through a router).

Bellow I am going to explain how to create traffic using the 2^nd option

Setup:

Create 1 traffic item with 10 flows tracked after the Source IP as bellow:

Flow 1   VLAN 101 Source IP=1.1.0.1 Destination IP=2.1.0.1

Flow2    VLAN 102 Source IP=1.2.0.1 Destination IP=2.2.0.1

………

Flow10  VLAN 110 Source IP=1.10.0.1 Destination IP=2.10.0.1

Configuration Steps:

     On Main Window go to Traffic Item and select to add a L2-3 Traffic item

    The Advance Traffic Wizard will open

    On Endpoint Page chose type of traffic Raw and send  from port 1 to 2

                            

      On Packet /QoS page perform the following settings:

Set the MAC destination address as : 00:00:02:00:00:1 

Clickon the small arrow  next to MAC value and chose to change the  value type Incremental  count 10

Perform similar setting on the MAC Source address

Mac Source=00:00:01:00:00:01 incremental count 10

Click on the Payload and then on Add Protocol button. On the popup window select to add VLAN

Make the VLAN incremental

Similarly Add IPv4 protocol to payload and make the Source/ Destination IP address incremental

    On the Flow Goup Setup page check that you want to create flows based on IPv4 Source Address

    On Frame setup change the Frame size to 1000B

    On the Rate Setup page change the rate to 1000pkts/seconds

    On Flow tracking page  chose to track  flows based on Ipv4 source address as we set on the flows 

Now you will see the newly created  Traffic Item  on the Traffic Item Window

In order for traffic to work you will need to apply it to the ports using the following button

As soon as traffic is applied you will see the green arrow next to it and you can start it.

Note:

If you want you can start just one  flow at a time by going on L2-3 flow groups window

After traffic is started you can see  the traffic  item statistics in the Main Statistics window

If yo would like to see statistics per flow chose to Drill down the statistics per IPv4 Source Address

IxNetwork Traffic- How to send multicast traffic

IxNetwork Traffic: Setup Multicast Traffic

Setup information:
Multicast source port: IP=1.1.1.1
Multicast destination port: IP=1.1.1.2, G=224.0.0.1
Traffic (S=1.1.1.1, G=224.0.0.1) 
For   sending multicast traffic ( if multicast routing  is already working) you will need to perform the following:
1. Configure  IGMP  protocol on the Multicast Destination ports
2. Configure the multicast traffic

Configuration steps:
1. Configure  IGMP  protocol on the Multicast Destination ports
Enable IGMP  protocol on the Multicast Destination ports

Make sure that IP addresses are configured properly. The Protocol Interface node button should be green:

Click on IGMP protocol node and go to Hosts tab.
Change the version of IGMP to 3 if necessary and set the number of groups to 1
Assign the connected interface and  check the Enable box

Configure multicast destination port  as IGMP host for multicast address G=224.0.0.1
Click on IGMP tab and go to Group Ranges:
In the Group IP configure the  multicast address and enable.

Start the IGMP protocol from the button: 

2. Create the multicast traffic:
Chose to add a L2-3 Item. 

On the destination side click on the button  with the cursor on. Select the destination as multicast:

*** Another way to set the traffic stream is to directly select as destination IGMP-> Multicast range. 

***In order for statistics to work properly in case you have more ports as destination for multicast traffic make sure that Merge Destination range is checked
