Testpmd Runtime Functions

When testpmd is started in interactive mode using the -i or --interactive option, a prompt is displayed that allows for real time configuration, statistic read-outs, and the ability to start/stop packet forwarding. Many of the testpmd command-line options can also be accessed as runtime functions.

An extensive number of testpmd runtime functions are available that are broken into multiple categories. See dpdk.org for a complete list:

To help with getting started, here are some examples of common runtime functions:

• set verbose (level): Set the debug verbosity level.
• set fwd (io|mac|macswap|flowgen|rxonly|txonly|csum|icmpecho|noisy|5tswap|shared-rxq) (""|retry): Set the packet forwarding mode.
• show port (info|summary|stats|xstats|fdir|dcb_​tc|cap) (port_​id|all): Display information for a given port or all ports.
• show fwd stats all: View statistics for all ports that were collected beginning from the time the forwarding engine was started.
• start: Start packet forwarding with current configuration.
• stop: Stop packet forwarding and display accumulated statistics.
