Emulator path for TX:022 RX:002

Emulator (TX) on 022

Resources (OFED and DPDK) are under /opt on 021 and 022. We use pktgen to generate a fix-rate flow of UDP JUMBO frames. Start pktgen with the pre-defined configuration via running as root the following script:

[root@np04-srv-022 opt]# pwd
/opt
[root@np04-srv-022 opt]# ./start-pktgen-txsetup.sh

The pre-defined configs are setting the destination MAC and IP addresses of np02-srv-002 already. You should see the pktgen control console GUI. You can modify different parameters of the packet generation.

Modify the rate to 1% of the available bandwidth of the output port:

Pktgen:/> set 0 rate 1

Modify the packet size to the size of a WIB-Ethernet Frame size (7192 Bytes):

Pktgen:/> set 0 size 7192

Start the flow of data on the port:

Pktgen:/> start 0

Receiver (RX) on 002

Setup a workarea as described on the devarea instructions.
