Traffic Generation
89
All the IPv4 datagram configuration lays within the Network menu. The network menu
is not enabled unless the port is configured in TX / RX mode. The procedure to follow
to configure the IP datagram is described below:
1. Make sure that your tester is connected to the network. The physical layer must
be up and working (See section 4.1.1). Check that your tester is operating in
IP Endpoint mode (See section 2.1) and that the port is in TX / RX.
2. From the Home panel, go to CONFIG,
The test port settings panel is displayed.
3. Select Port A or Port B to enter in the port specific configuration.
4. Enter in the Network layer menu.
UDP Enables or disables transmission of the User Datagram Pro-
tocol (UDP) in the current stream.
The UDP is defined in RFC 768 and it is a lightweight trans-
port protocol for unreliable data transmission. RFC 768
defines an eight-byte fixed length header for UDP that is gen-
erated when UDP generation is enabled in the stream.
If UDP generation is on, the Transport protocol field is set to
17. This value cannot be edited by the user.
Transport protocol This setting contains an 8-bit word that constitutes the proto-
col identifier to be transmitted by the traffic generator.
TCP uses 6 as the protocol number, UDP uses 17 for the
same purpose and ICMP uses number 1. However, the pay-
load structure does not match the structure corresponding to
these protocols even if the correct protocol number is config-
ured. To enable UDP header and payload generation, enable
UDP in the current stream.
Source port Source transport layer port transmitted in the UDP header in
the current stream.
Ports are service identifiers used to multiplex data from differ-
ent applications generated by IP hosts. The tester supports
source port generation for UDP streams only.
Destination port Destination transport layer port transmitted in the UDP
header in the current stream.
Ports are service identifiers used to multiplex data from differ-
ent applications generated by IP hosts. The tester supports
destination port generation for UDP streams only.
