Description
Configuration of the packet generator format. The packet generator is a
UDP packet generator that is compatible with iPerf software in UDP mode.
Typical use cases for the traffic generator and traffic monitor:
•
Generate traffic on a modulator and monitor this traffic on a
demodulator.
•
Generate traffic from an iPerf client on a PC and monitor this traffic
on a modulator or demodulator (via a modulator).
•
Generate traffic on a modulator and monitor this traffic on an iPerf
server on a PC (via a demodulator).The generator format can be
defined by space-separated sequence of the following criteria:
•
vlan==5
•
eth.dst==00:11:22:33:44:55 (hex)
•
eth.src==00:11:22:33:44:55 (hex)
•
ip.src==1.2.3.4
•
ip.dst==1.2.3.4
•
ip.len==1200
•
udp.dst==5001 (or 0x1389)
•
raw[12]==ab (hex)The destination UDP port defaults to 5001 (just
like in iPerf). In most situations, it is sufficient to configure a
destination IP address and a VLAN, if VLANs are used.Example for
setting up a traffic generator on a modulator that sends data to a
traffic monitor on a demodulator:1) Configure the packet monitor on
the demodulator: - Action = rx to packet monitor - Filter =
ip.dst==2.2.2.2 - Probe = All EthTx packets2) Configure the packet
generator on the modulator: - Probe = Eth RX interface - Packet
format = vlan==5 ip.dst==2.2.2.2 - Bitrate = 1000000 - Bytes to
transmit = 1000000The packet monitor will stop itself, when the last
packet of a session has been received. This last packet is detected
by a negative sequence id in an iperf-proprietary part of the packet.
