Compound Module EtherHost

Package: inet.nodes.ethernet
File: src/nodes/ethernet/EtherHost.ned

An example host with one Ethernet port and traffic generators that generate Ethernet traffic directly. This host model does not contain higher layer protocols (IP, TCP).

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

LargeLAN (compound module)	Several hosts and an Ethernet hub on a switch. One port of the hub connect to a 10Base2 segment.
MediumLAN (compound module)	Several hosts and an Ethernet hub on a switch
SmallLAN (compound module)	Several hosts on an Ethernet hub

Networks:

BusLAN (network)	Sample Ethernet LAN: four hosts on a bus.
HubLAN (network)	Sample Ethernet LAN: four hosts connected by a hub.
LargeNet (network)	A large Ethernet LAN -- see model description here.
MixedLAN (network)	Sample Ethernet LAN containing eight hosts, a switch and a bus.
SwitchedLAN (network)	Sample Ethernet LAN: four hosts connected to a switch.
TwoHosts (network)	Sample Ethernet LAN: two hosts directly connected to each other via twisted pair.

ethg	inout

Unassigned submodule parameters:

Name	Type	Default value	Description
cli.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
cli.startTime	double	this.waitTime	time of sending the first request
cli.waitTime	double	uniform(0s,1s)	interval between sending requests
cli.reqLength	int	100B	length of request packets
cli.respLength	int	1KB	length of response packets
mac.promiscuous	bool	false	if true, all packets are received, otherwise only the ones with matching destination MAC address
mac.address	string	"auto"	MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.
mac.txrate	double	100Mbps	maximum data rate supported by this station (bit/s); actually chosen speed may be lower due to auto- configuration. 0 means fully auto-configured.
mac.duplexEnabled	bool	true	whether duplex mode can be enabled or not; whether MAC will actually use duplex mode depends on the result of the auto-configuration process (duplex is only possible with DTE-to-DTE connection).
mac.txQueueLimit	int	1000	maximum number of frames queued up for transmission; additional frames are dropped. Only used if queueModule==""
mac.mtu	int	1500
