Unassigned submodule parameters:

Name	Type	Default value	Description
hostA.cli.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
hostA.cli.startTime	double	this.waitTime	time of sending the first request
hostA.cli.waitTime	double	uniform(0s,1s)	interval between sending requests
hostA.cli.reqLength	int	100B	length of request packets
hostA.cli.respLength	int	1KB	length of response packets
hostA.mac.promiscuous	bool	false	if true, all packets are received, otherwise only the ones with matching destination MAC address
hostA.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.
hostA.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.
hostA.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).
hostA.mac.txQueueLimit	int	1000	maximum number of frames queued up for transmission; additional frames are dropped. Only used if queueModule==""
hostA.mac.mtu	int	1500
hostB.cli.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
hostB.cli.startTime	double	this.waitTime	time of sending the first request
hostB.cli.waitTime	double	uniform(0s,1s)	interval between sending requests
hostB.cli.reqLength	int	100B	length of request packets
hostB.cli.respLength	int	1KB	length of response packets

hostC.cli.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
hostC.cli.startTime	double	this.waitTime	time of sending the first request
hostC.cli.waitTime	double	uniform(0s,1s)	interval between sending requests
hostC.cli.reqLength	int	100B	length of request packets
