What is Trex traffic generator?

TRex is an open source, low cost, stateful and stateless traffic generator fuelled by DPDK. It generates L3-7 traffic and provides in one tool capabilities provided by commercial tools.

How do you use Trex in CML?

Using Trex Nodes in CML

An initial user account will be created when the VM boots. By default, a cisco account with password cisco is created. You can override the username and password for this initial user account by setting the USERNAME and/or PASSWORD in the Edit Config pane for the node in the Workbench.

How does a traffic generator work?

A traffic generator is used to put traffic onto a network for other machines to consume. Logically, a traffic generator has a physical layer address (and usually higher-level address), because it is supposed to look like a machine on the network to the target machines receiving the traffic.

What is Cisco TRex used for?

TRex is a traffic generator for Stateful and Stateless use cases. 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).

How do I monitor my TRex?

T-Rex comes with a built-in web monitoring/control page. By default, it is only accessible from the same PC where the miner is running - http://127.0.0.1:4067/. If you would like to use it from other machines in your local network you need to set --api-bind-http parameter, e.g. --api-bind-http 192.168.

Is Ostinato free?

Ostinato - Free download and software reviews - CNET Download.

How do I enable the watchdog on my Trex?

By default, T-Rex has watchdog disabled. To enable it, change option "no-watchdog":true to be "watchdog-exit-mode":"N:M:A" instead: N is number of restarts. M is number of minutes in which N number of restarts needs to occur to trigger the watchdog.

What is drop rate in Cisco Trex?

The default value is 1%. pdr (percentage of drop rate) represents the allowed percentage of drops, out of total traffic. The default value is 0.1%.

What is the difference between CML Personal and Personal Plus?

The difference between "Cisco Modeling Labs-Personal" and "Cisco Modeling Labs-Personal Plus" is the number of available nodes, 20 and 40, respectively.

What are Trex capabilities?

TReX has the capability to mimic specific threat radio waveforms including but not limited to: Fast, frequency hopping tactical radios. Fixed-frequency tactical radios.

What is stateful traffic generator?

WARP17, The Stateful Traffic Generator for L1-L7 is a lightweight solution for generating high volumes of session based traffic with very high setup rates. WARP17 currently focuses on L5-L7 application traffic (e.g., HTTP) running on top of TCP as this kind of traffic requires a complete TCP implementation.

What are T. rex weaknesses?

What is a Tyrannosaurus rex weakness? Although Tyrannosaurus rex is known for its sharp claws and teeth, this dinosaur also had a few weaknesses. One of them is the presence of extremely short arms, which were too short to be used for eating or grasping items.

Why is T. rex so strong?

The fearsome Tyrannosaurus rex could generate tremendous bone-crushing bite forces thanks to a stiff lower jaw. That stiffness stemmed from a boomerang-shaped bit of bone that braced what would have been an otherwise flexible jawbone, a new analysis suggests.

How many MPH can at Rex run?

One previous study of a single footprint of a large tyrannosaur suggests that the beast could have been traveling as fast as 11 kilometers per hour (6.8 miles per hour), says Eric Snively, a vertebrate paleontologist at the University of Wisconsin, La Crosse.

What are 5 common traffic control devices?

Devices typically used include speed bumps, barricades to block streets, turn prohibitions, stop signs, and raised pavement markers. Traffic restraint also includes programs to foster bicycle and pedestrian travel.

What are the 3 types of traffic control devices?

Traffic Control Devices include street signs, traffic signals, and road markings. These signs, signals, and stripes guide drivers in navigation and control of their vehicles.
