Compound Module EtherSwitch2

Package: inet.nodes.ethernet
File: src/nodes/ethernet/EtherSwitch2.ned

Model of an Ethernet switch built with EtherMAC2, which means that all ports are operating in strictly full-duplex mode. Use EtherSwitch if you need half-duplex operation on some ports.

This model does not contain the spanning tree algorithm.

Unassigned submodule parameters:

Name	Type	Default value	Description
relayUnit.addressTableFile	string		set to empty string if not used
relayUnit.addressTableSize	int		max size of address table
relayUnit.agingTime	double		max idle time for address table entries (when it expires, entry is removed from the table)
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.txQueueLimit	int	1000	maximum number of frames queued up for transmission; additional frames are dropped. Only used if queueModule==""
mac.mtu	int	1500
