The vulnerability is due to a missing bounds check in the handling of the Transport Layer Security TLS heartbeat extension. Found this mentioned in the release notes : In new instances the admin user will now start with a randomly generated password. Example use cases:. The examples illustrate novel traffic generation techniques made possible by TRex.
TRex is a Linux application, interacting with Linux kernel modules. Our regression setups uses Cisco UCS hardware for high performance low latency use cases. The following platforms have been tested and are recommended for operating TRex. In this way TRex can run almost on any Linux platform and any Linux interfaces e.
Docker example is provided Docker for more info see low footprint and Linux interfaces.
Preferred Low-End. See table below describing cisc. Both left and right should support x16 PCIe. Right Riser1 should be downloxd option A x16 and Left Riser2 should be x Need emultor order both. Fewer channels will impose a performance issue. The only Napatech NIC in our regression.
PCIe bifurcation. ASTF only one core. These are generally accomplished using multipacket buffering. For best performance, loopback the interfaces on the same NUMA controlled by the same physical processor. If you are unable to check this, proceed without this step. If you encounter link issues, try to loopback interfaces from different NICs, or use Cisco twinax copper cable.
Choose the ports to use and follow the instructions in the next section to create a configuration file. For many purposes, it is convenient to begin with a copy of the basic configuration file template, available in the cfg folder:. A script is available to automate the process of tailoring the basic configuration file to your needs.
The script emu,ator you started, and then you can then edit the resulting configuration file directly for advanced options. The script provides a list of available interfaces with interface-related information. Follow the instructions to create a basic config file. Create a configuration file by specified interfaces PCI address or Linux names: clsco etc.
Destination MACs to be used per each interface. List of IPs to use for each interface. List of default gateways to use for each interface.Cisco - Networking, Cloud, and Cybersecurity Solutions
Cores exclude: Black list of cores to exclude. When excluding cores, ensure that enough remain for each NUMA. No HyperThreading: Use only one thread of each core specified in the configuration file. Advanced option Prefix to be used in TRex configuration in case of parallel instances.
This option may reduce performance. Use only if necessary - for example, in case of a pair of interfaces at different NUMAs. General recommendation: For best performance, run TRex on "bare metal" hardware, without any type of VM. Bandwidth on a VM may be limited, and IPv6 may not be fully supported. One of the NICs must be connected to the main vSwitch network for an "outside" connection for the TRex client and ssh:.
The vSwitch did not route packets correctly. This downloas was resolved in version 2. Passthrough settings cannot be saved to OVA. Mark the desired NICs. Right-click the guest machine. Another interesting low-end use case is cisco native Linux interfaces. Starting from version 2.
It wraps a share memory infra ring. There is a foursome of arguments to interconnect 2 memifs to communicate: socketidrole and secret. Socket is for exchange of protocol control messages. Secret is optional string platform default empty wich has to match. The Linux interfaces reside in separate network namespace in order to have their own ARP tables and not interfere with the disco of system.
It can be extended in future to:. Many [thousands] emulated clients, while TRex port is emulator as switch connecting all that clients. Client Python API, trex-console older than v2. Update your client to v2. It provides similar capabilities found in Linux bonding driver.
Link Aggregation See here for the details. The bonded device inherits attributes from the first slave device. All slave devices should have same doownload and duplex. You can follow this presentation for an example of how to configure the router as a DUT. Though not present in the above output, measuring latency and jitter is possible!
Estimate of number of L4 ports sockets used per client IP. In this scenario, it is useful for all numbers displayed by TRex to be multiplied by ucs factor, so that TRex counters will match the DUT counters. The following is a simple example helpful for understanding how TRex works.
The example uses the TRex simulator. This simulator can be run on any Cisco Linux including on the TRex itself. TRex simulates clients and servers and generates olatform based on the pcap files provided. In basic usage, TRex does not wait for an initiator packet to be received.
3.1 response packet will be triggered based only on timeout IPG in this example. Usc advanced scenarios for example, NATthe first packet of download flow will be processed by TRex and initiate the response packet only when a packet is received.

Consequently, it is necessary to process the template pcap file offline and ensure that there is enough round-trip delay RTT between client and server packets. Take a look at: astf-sim for fixing pcaps Another approach is to change the yaml ipg field to a high enough value bigger than 10msec. Use the following to display the output as a chart, with: x axis: time seconds y axis: flow ID The output indicates that there are 10 flows in 1 33.1, as expected, and the IPG is 50 msec.
Note the gap in the second flow generation. This is an expected schedular artifact and does not have an effect. In this example, the IPG was taken from the pcap file, which is closer to 20 msec and not 50 msec taken from the configuration file.
In this case there is only one client so only ports are used to distinc the flows you need to be sure that you have enogth free sockets when running TRex in high rates. See the following example. SFR traffic includes a combination of traffic templates. This traffic mix in the example below was defined by SFR France. The traffic was recorded from a Spirent C with a Pagent that introduce 10msec delay from client and server side.
TRex commands typically include the following main arguments, but only -f is required. With this feature you can "repeat" flows and create stateless, IXIA ddownload streams.

After injecting the number of flows defined by limitTRex repeats the same flows. If all templates have limit the CPS downlload be zero after some time as there are no new flows after the first iteration. The -p is used here to send the client side packets from both interfaces. Normally it is sent from client ports only.
Downlload this option, the port is selected by the client IP. All the packets of a flow are sent from the same interface. PBR router configuration solves this issue but cannot be used in all cases. So use this -p option carefully. This configuration file creates flows that will be repeated as follows: f1f2f3 …. It is possible to mix stateless templates and stateful templates.
Currently, there is one global Emylator pool for clients and servers. It serves all templates. All templates will allocate IP plstform this global pool. It is required when the number of clients is very small and the template defines a very long duration. For example, with four ports, we would have get the following ip range is :.

When using -p option, TRex will not comply with the static route rules. Server-side traffic may be sent ucs the client side port 0 and vice-versa. If you use the -p option, you must configure policy based ucz to pass all traffic from router port 1 to router port 2, and vice versa.
VLAN feature does not comply with static route rules. Limitation: When using template with plugins bundlesthe number of servers must be higher emulator the number of clients. This 3-tuple should be distinct among active flows. Currently, only sequential distribution is supported in IP allocation. Dowmload means the IP address is increased by one for each flow.
For example, if we have a pool of two IP addresses: The above formulas can be used to calculate the PPS. The TRex throughput depends on the PPS calculated above and the meulator cisco m a multiplier ucz as command line argument -m. The m value is a multiplier of total pcap files CPS. CPS of pcap file is configured on yaml file.
The BPS depends on the emulaor size. This option measures downloax and jitter. This is particulary usefull if your DUT drops traffic from outside, and you need to open pin hole to get emulatof 3.1 traffic in for example when testing a firewall. The command output of the t-rex download with latency stats enabled looks similar to the following:.
One useful application of this can be in a lab setup where you have one TRex and many DUTs, and you want to test a different DUT on each 3.1, without changing cable connections. This feature converts asymmetric traffic to symmetric, from the port perspective, emularor router sub-interfaces.
Without VLAN support, the traffic is asymmetric. In this case, traffic on vlan0 is sent as before, while for traffic on vlan1, the order is reversed client traffic sent on port1 and server traffic on port0. TRex download the flows evenly downlload the vlans. This results in an equal amount of traffic on each port. This is ciscp mode.
Ability to generate IPv6 traffic from pcap wmulator containing IPv4 packets. The --ipv6 command line option enables this feature. The --ipv6 switch must be specified even when using a pcap file containing only IPv6 packets. TRex supports testing complex topologies with more than one DUT, using a feature called cksco clustering". This feature allows specifying the distribution of clients that TRex emulates.
There are two clusters of DUTs. Using the configuration file, you can partition TRex emulated clients into groups, and define how they will be spread between the DUT clusters. The following example uses the MAC address. The instructions after the example indicate how to change to Emulator. The above configuration divides the generator range of clients to two clusters.
Downloaf range of IPs in all groups in the client configuration file must cover the entire range of client IPs from the traffic profile file. If none is found, TRex exits with an error message. For example, in a MAC-based configuration:. Latency streams client IP is taken from the first IP in the default client pool.
Each dual port will have one Client IP. In case meulator cluster configuration this is a limitation as you can have a topology with many paths. For example, in this case cisco The folowing figure shows the topology. Latency stream will check only DUT should have a static route to move packets from client to server ucs vice versa, as traffic is rownload in the same subnet of the ports.
Associate the next-hop from cluster pool. In this case In this example there TRex has two dual ports. We can use traffic mask to differentiate the ip range. The profile download is the similar to the previous one with the difference that we need to add more mapping in the cluster file. Latency can be tested on another path in the configuration.
To learn the NAT translation, Cisco must embed information describing which flow a packet belongs to, in the first packet of each flow. UDP flow : Flow information is embedded in the IP identification field of the playform packet platform the flow. This mode was developed for testing NAT with firewalls which usually do not work with mode 2.
TRex can learn and compensate for seq num randomization in both directions of platform connection. This lpatform header is added only to the first packet in the flow. This mode can provide better connections-per-second performance than mode 1. But 3.1 all existing firewalls, the mode 1 cps rate is adequate. The client address range is In normal mode without the feature enabledreceived traffic is not checked by software.
Hardware Intel NIC testing for dropped packets occurs at the end of the test. This feature changes the TTL of the sampled flows to and expects to receive smulator with TTL or one routing hop. If you emulator more than one .31 in your setup, use --hops to platform it to a higher value.
More than one hop is possible if there are number of routers betwean TRex client side and TRex server side. There are no packet drops no need to wait for the end of ciscco test. Without this flag, you must wait for the end of the test in order to identify packet drops, because there is always a difference between TX and Rx, due to RTT.
Use --hop ucs configure this value. Masked interfaces, to ensure that TRex does not try to use the management ports as traffic ports. If you use version earlier than 2. For an example config, you can look here. The memory section is optional. It is used when there is a need to tune the amount of memory used by TRex packet manager.
Default values from the TRex source codeare usually good for most users. Unless you have some unusual needs, you can eliminate this section. The platform section is optional. It is used to tune the performance and allocate the cores to the right NUMA a configuration file now has the folowing struct to support multi instance. They shared the same Cisoc.
The flow scheduler uses a timer wheel to schedule flows.

To tune it for a large number of flows it is possible to change the default values. An experimental switch to scale up or down the number of active flows. It is not accurate due to the quantization of flow scheduler and in some cases does not work. Period in seconds between sending of gratuitous ARP for our addresses. Since version 2. Flag that specifies advanced stateful mode.
Currently works as batch, WIP on adding interactive support. Number of hardware threads to use per interface pair. Use at least 4 for TRex 40Gbs. TRex uses 2 threads for inner needs. Rest of the threads can be used. Maximum number here, can be number of free threads divided by number of interface pairs.
