Example pktgen Configuration

This section provides a more complex example of a pktgen command.

This command starts pktgen with these EAL parameters:

• -l <core list>: List of cores to run on, where ‘-‘ is used as a range separator and ‘,’ is used as a single number separator.
• -n <number of channels>: Set the number of memory channels to use.
• --proc-type: Type of this process.
• --log-level:
• --socket-mem: Memory to allocate on specific sockets (use comma separated values)
• --file-prefix: Prefix for hugepage filenames
• -a, --allow <[domain:]bus:devid.func>: Add a PCI device into the list of devices to probe.

1. Example pktgen configuration command: ./pktgen -l 24-32 -n 4 --proc-type auto --log-level 7 --socket- mem=0,1024 --file- prefix pgb2000 -a b2:00.0 -- -N -P -T -m [25-28:29-32].0
2. Pktgen entropy configuration to enable multiple traffic streams with RSS: Pktgen:/> set 0 proto tcp Pktgen:/> set 0 size 128 Pktgen:/> set 0 src mac 68:05:ca:a6:0b:1c Pktgen:/> set 0 dst mac 68:05:ca:a6:0a:b0 Pktgen:/> set 0 src ip 192.168.103.101/24 Pktgen:/> set 0 dst ip 192.168.103.102 Pktgen:/> enable 0 range Pktgen:/> range 0 proto tcp Pktgen:/> range 0 size 128 128 128 1 Pktgen:/> range 0 src mac 68:05:ca:a6:0b:1c 68:05:ca:a6:0b:1c 68:05:ca:a6:0b:1c 00:00:00:00:00:01 Pktgen:/> range 0 dst mac 68:05:ca:a6:0a:b0 68:05:ca:a6:0a:b0 68:05:ca:a6:0a:b0 00:00:00:00:00:01 Pktgen:/> range 0 src ip 192.168.103.101 192.168.103.101 192.168.103.101 0.0.0.1 Pktgen:/> range 0 dst ip 192.168.103.102 192.168.103.102 192.168.103.102 0.0.0.1 Pktgen:/> range 0 dst port 2000 2000 2000 1 Pktgen:/> range 0 src port 3000 3000 3016 1 Pktgen:/> start 0 Note: The above configuration can be saved to a file and loaded directly to the pktgen. Pktgen:/> save <path-to-file> Pktgen:/> load <path-to-file>
