Port SERVICEACCESS - UDP-PCAP-SOCKET 🛈¶
PCAP-based network stack UDP
This port is only available if Npcap is installed.
Stimulation¶
This port has no stimulus capabilities.
Properties 🛈¶
Name |
Available if |
Default value |
Valid values |
Type |
Description |
|---|---|---|---|---|---|
Network interface card |
string |
The network interface card or network adapter to be used for receiving network packets |
|||
Receive buffer size |
1000 |
int |
Number of messages which can be recorded in the receive buffer (ring buffer) |
||
Keep cyclic sending active |
☐ |
bool |
If the check mark is set, the cyclical sending of packets is only stopped at port stop or by the explicit call to ‘StopSendPacketCyclic’. Otherwise (default), the cyclic sending is already terminated at the end of the test. |
Jobs 🛈¶
ClearReceiveBuffer¶
Clears the ecu.test high-level receive buffer. Low-level buffers in the driver are not cleared.
CloseConnection¶
Closes opened UDP connections
ConnectionInfo¶
Provides IP addresses and ports of the connected network end point.

Type |
Description |
|---|---|---|---|---|---|
DevGw |
string |
String (Format: 192.168.0.1 / fd48:a7e0:36c1:42b6::1), Empty when the gateway is not needed |
|||
DevIp |
string |
Local IP address as a string (format: 192.168.0.1 / fd48:a7e0:36c1:42b6::1).

|||
DevSubnetMask |
‘Default’ |
string |
For IPv4 addresses a subnet mask or prefix length can be given (format: ‘255.255.255.0’ or ‘24’). ‘default’ uses the default subnet mask of the IP address’s (DevIp) network class. For IPv6 only a prefix length is accepted and the value ‘default’ is not supported. |
