The GUI version (packETH) you can create and send packets. With the CLI version (packETHcli) you can only send already stored packets from pcap file. The CLI version also has a receiver mode, that can count packets and check if all packets that were sent were also received.

There is a large list of advanced features for testing network. You can create and send any ethernet packet. Supported protocols:

  • Ethernet II, ethernet 802.3, 802.1q, QinQ, user defined ethernet frame
  • ARP, IPv4, IPv6, user defined network layer payload
  • UDP, TCP, ICMP, ICMPv6, IGMP, user defined transport layer payload
  • RTP (payload with options to send sin wave of any frequency for G.711)
  • JUMBO frames (if network driver supports it)

User may send a sequence of packets. the tool will allow to have the following options:

  • Delay between packets, number of packets to send
  • Sending with max speed, approaching the theoretical boundary
  • Change parameters while sending (change IP & mac address, UDP payload, 2 user defined bytes, etc.)
  • Size and speed ramp option

Once the test is completed user may save the configuration to a file and load from it – pcap format supported.
