Since version 2. I would like to describe how we tested this, and the performance we have seen. For network cards, this means the ability of one card to appear as if it was few separate cards called virtual functions VFseach with its own PCI address. This is particularly useful on virtual machines environments, where you have one NIC, and you want each VM to view it as if it is the only consumer.
The below link for example gives very good explanation:. We used Centos 7. Now, when running:. You should see lines like this:. These are the ports that should be used in TRex config file. TRex stateful performance. Using the following command, running on x card with VF driver, we can see that TRex can reach 30GBps, using only one core. We can also see that the average latency is around 20 usec, which is pretty much the same value we get on loopback ports with x physical function without VF.
Cpu Utilization : TRex stateless performance Using stateless with one core with x VF: sudo. Port Status. With the console command:. We can see, that we can reach 8M packet per second, which in this case is around Global Statistics. Port Statistics. CPU util. Line Util.

The abilities and scale of this product posed a challenge from a testing point of view. The requirements for the testing included:. As a former leader of the Openstack QA Activities, I started diving into a new Open Source Project to find a solution traffic generator that would answer my testing environment requirements.
Why TRex? TRex Configuration File:. The Mellanox Traffic Mix represents Mellanox' s view of the traffic in relevant locations in the network. It has been verified by key vendors and is tuned toward traffic in the data center. Mellanox is using this traffic mix when profiling and optimizing its stateful L technologies.TRex- fast open source traffic generation tool by Ido Barnea
Although different, both the SFR traffic profile and the Mellanox traffic profile are attempts at depicting average stateful traffic. A key differentiator between the profiles is the number of concurrent flows i.
This profile exercises the DUT performance too, and we expect that a similar feature running on x86 will experience a performance degradation with our Mellanox traffic profile. We could have improved TRex performance by creating a distribution of flows over time as described in the manual, but we chose not to do so. Snapshot of TRex run Console:. TRex Missing Functionality:.
The following items are lacking from TRex in our view:.Composite Software, Inc was previously a privately held data virtualization software company based in San Mateo, California. Composite Software was founded in October by Michael R. Composite Software was cited as an "industry leader" in the Forrester Research " Forrester Wave: Data Virtualization" study for its help in advancing data virtualization to its current form, known under a variety of names including data federation and Information as a Service.
The Composite Data Virtualization Platform is data virtualization middleware that "brings together data from multiple, disparate sources -- anywhere across the extended enterprise-- into a unified, logical virtualized data layer for consumption by nearly any front-end business solution including portals, reports, applications and more.
Composite Software's data virtualization software is used in financial services companies, pharmaceutical companies, energy companies, communications, consumer and industrial companies, and government agencies including the U.
Army and the Environmental Protection Agency. It continues to be sold to address the same use cases at large enterprise customers,  and is also central to Cisco's move into data and analytics  associated with the Internet of Things.

Here is a step by step installation instruction:. Please, follow this link. You can open it from the Stats menu or by click on the dashboard icon in top-right corner of the main window. At the top of the dashboard you can see global TRex statistics. Global statistics contains ten panels which represents main TRex statistics.
Four of them have an color indicator which is green if value is good and red if it is not. Ports statistics table represents total information about all selected ports and detail information about each of it. Here is two rows which have color indicator with good value threshold equals to 0. It are oerrors and ierrors. Latency window table represents detail information about the last ten temporary max latencies, jitter, max latency, avg latency and common information about the errors.
Errors row has color indicator with good value threshold equals to 0. Latency window table represents detail information about the latencies and errors. All error rows have color indicator with good value threshold equals to 0. You need to enable RX stats for Streams in order to see them on charts:. Port attributes tab displays detailed port information and provides capabilities to modify port attributes such as Multicast, Promiscuous, Flow control and others. Also it is possible to control port's service mode right from the GUI.
Also you can ping hosts with properly configured L3 mode. IPv6 is supported also. Pinging IPv6 hosts works also. If you have real NIC you probably need to see hardware counters for debugging purposes or any other matters.
By default non-zero counters is visible.
If you need to find certain counter you can specify it's name in the filter and pin interested one and see the value despite on filter options. User can monitor activity on TRex ports without connecting to the TRex console. It is very useful capability which completes full lifecycle of traffic generation. The are two ways to see captured packets in realtime. And the second one is launch monitoring in Wireshark.
To open Packet Editor you need to click on "Advanced mode" button in stream editor window. You can select available suggested layers, or type any layer you want to produce a malformed structure.
Click on a append field and start typing - autocompletion will show all available variants without restrictions. Packet editor is flexible and uses Scapy to build packets. It allows to create malformed packets, and shows a warning red label on a layer name. You can move and remove any layer except Ether by the right-click on the layer title.
Use template-code and specify the target size of a payload of a whole packet you want. Template code is a hex string. You can upload a binary file as a payload.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again.

Traditionally, network infrastructure devices have been tested using commercial traffic generators, while the performance was measured using metrics like packets per second PPS and No Drop Rate NDR. As the network infrastructure functionality has become more complex, stateful traffic generators have become necessary in order to test with more realistic application traffic pattern scenarios.
Realistic and Stateful traffic generators are needed in order to:. Flexibility : Commercial tools do not allow agility when flexibility and changes are needed. Testing in low scale and extrapolation became a common practice, it is not accurate and hides real life bottlenecks and quality issues. Generates L traffic and able to provide in one tool capabilities provided by commercial tools.
Virtualization support. Enable TRex to be used in a fully virtual environment without physical NICs and the following example use cases:. It is more packet based.
Build and run Cisco Trex traffic generator
Large-scale - Supports about million packets per second Mpps per core, scalable with the number of cores. The framework can be extendable with new protocols. The following example shows three streams configured for Continuous, Burst, and Multi-burst traffic.
This opens the following new capabilities:. In this case, there is a different TCP session on each side, but L7 data are almost the same. Ability to work in either client mode or server mode. This way TRex client side could be installed in one physical location on the network and TRex server in another. Emulate L7 application, e. ASTF documentation. ASTF Performance. New Stateless support. DPDK summit Github is here trex-stateless-gui.
The objective is to implement client side L3 protocols i. This project is not limited to client protocols, but it is a good start.
The project provides a framework to implement and use client protocols. The framework is fast enough for control plane protocols and will work with TRex server. Each of the aforementioned protocol is implemented as a plugin. These plugins are self contained and can signal events one to the other, or to the framework, using an event-bus. The framework has an event driven architecture, this way it can scale. The framework also provides to a protocol plugin infrastructure, for example RPC, timers, packet parsers, simulation and more.

Skip to content.January 10, The 1GbE port is only being utilized to manage the system ie control-plane and the 10GbE ports are strictly for test data data-plane. General TRex configuration file. TRex will use the MAC addresses here to rewrite generated packets toward it's destination.
Perhaps the most practical use of TRex, this is actually an optional configuration file useful for testing a single or multiple devices with a single test.
Note the following configuration elements:. This allows me to change the VLAN in which I want to run tests without touching the switchport configuration.
This boolean must be specified as true or false. You will need to configure IP routes for the TRex client Use the 'Command Line' section of the TRex manual to tweak certain things, like traffic rate, etc. Some benefits of using VTI is it that does away with the painful requirement of configuring all of those joyless static crypto map access-lists, meaning you no longer have to manually maintain all possible local-to-remote prefix security associations.

Note that no special hardware SSD, etc is needed on the Firepower series devices to support this configuration. A quick housekeeping aside: To anyone who reads this article and believes that one is giving up security by replacing FTD with ASA, I strongly contend that you're probably wrong about that.
Also, if from reading this it sounds as though I'm being harsh toward Cisco and their Firepower product team's top-level decision making, it's only because it actually is that terrible. Concepts and Key Terms Cisco's Firepower isn't actually a product in and of itself but a suite of products and subcomponents. For those uninitiated with the breakdown, it's important to understand what those components are for this procedure.
