APIC EM and TRex - A collaboration for testing a complex network topology

Worked with the APIC EM testing team to provide a way for TRex (Cisco open source traffic generator) to test a complex network topology.

 Using APIC EM controller for configuring your network might impose a challenge on how to test a complex topology. This has led the APIC EM team to request TRex dev team to provide a way to test a more complex topology.

 Let's take a look at the following topology:

 We wish to test this topology with a range of clients communicating with a range of servers.

Testing this kind of a network topology requires a way to divide the range of the clients to the clusters by providing: 

1. Different VLANs for both directions

2. Different MAC addresses for each cluster

3. A way to direct different amount of traffic to each cluster

 In TRex we were able to adapt to the need in less than two weeks !

The solution is based on a well known standards such as YAML format for configuration:
