Port SERVICEACCESS - UDP-RAW 🛈

UDP low level communication

Stimulation

This port has no stimulus capabilities.

Properties 🛈

Name	Available if	Default value	Valid values	Type	Description
Port				string	Name of the port inside a network. In Vector Hardware Config, the network-based mode must be activated.
Filter in BPF format		‘(ip dst host [IP] or ip[16] >= 224) and ip proto \udp and src port [DEST-PORT] and dst port [SRC-PORT]’		string	The identifiers [IP], [DEST-PORT], [SRC-PORT] in square brackets describe variables that are replaced with the corresponding value when the configuration is loaded. By default, filtering is based on the default source port as destination and the default receive port as source. [IP] corresponds to the port IP address. Caution: The filter may only filter UDP packets, since other transport protocols cannot be interpreted. VLAN filtering happens automatically when enabled. If UDP packets are transmitted in fragmented IP packets, there must be no filtering on ports.
VLAN settings		‘no tagging’	[‘no tagging’, ‘single tagging’]	string	Used VLAN setting
VLAN-VID		1		int	Integer, only used if VLAN tagging is enabled
Disable LibPcap buffering		☐		bool	Disable internal LibPcap buffering
Receive buffer size		1000		int	Number of messages which can be recorded in the receive buffer (ring buffer)
Automatic data reception on test run		☑		bool	Only operative if on the left for ‘Start’ either ‘Always’ is chosen, or ‘If necessary’ and the port is in use in the test configuration.
Path / file name for the PCAP/PCAPNG output file	Automatic data reception on test run			string	PCAP or PCAPNG file (with absolute path). Recording is done into this file. Leave blank if no recording is desired.
Default source MAC address		‘02:00:4C:4F:4F:50’		string	Default MAC address to be used for Ethernet frames
Default source IP address				string	Default IP address to be used for IP packets
Subnet mask for IP network				string	Subnet mask for the IP Network (necessary in order to recognize broadcast addresses, e.g. for ARP)
Default source port		30490		int	Default port to be used as source in the UDP header
Default destination port		30491		int	Default port to be used as destination in the UDP header

Jobs 🛈

ClearReceiveBuffer

Clears the ecu.test high-level receive buffer. Low-level buffers in the driver are not cleared.

ReceivePacket

Returns a packet from the receive buffer and removes it from there

Parameterization

Return value

Name	Available if	Default value	Valid values	Type	Description
result				string	Return value of type PacketUdp or NotPresent

ReceiveSomeIpMessage

Returns a packet from the receive buffer, interprets it and filters the MessageId if necessary. If MultipleResults are enabled, a list with more than one object might be returned. The packet will be removed from the receive buffer.

Parameterization

Parameter

Name	Available if	Default value	Valid values	Type	Description
InterpretAs		‘PacketSomeIp’	[‘PacketSomeIp’, ‘PacketSomeIpSd’]	string	Specifies which class a package is to be interpreted by. A packet is only returned if it could be successfully interpreted.
MessageId				object	MessageIds which have to match for passing (empty / int / list with ints)
MultipleResults		False	[False, True]	bool	Boolean, if enabled a list with result objects will be returned

Return value

Name	Available if	Default value	Valid values	Type	Description
result				string	Return value of specified type, list of it or NotPresent
