Cisco TRex realistic traffic generator
TRex is an open source, low cost, stateful and stateless traffic generator fuelled by DPDK. This snap packages the TRex server, console and Python automation client from the upstream trex-core source.
The server runs in af_packet mode on kernel interfaces, without hugepages or NIC driver binding. DPDK PCI mode is not supported under strict confinement.
Setup
sudo snap connect trex-generator:network-control
sudo snap connect trex-generator:hardware-observe
sudo snap connect trex-generator:process-control
sudo snap connect trex-generator:system-observe
Configuration
Configuration files, scripts and their output live in
/var/snap/trex-generator/common. Select the server configuration with
sudo snap set trex-generator config=<path relative to that directory>
(default trex_cfg.yaml), or pass --cfg <absolute path>.
Commands
