This module handles the mapping between ports and MAC addresses.

Entries are deleted if their age exceeds a certain limit.

If needed, address tables can be pre-loaded from text files at the beginning of the simulation; this controlled by the forwardingTableFile module parameter. File format: line oriented table with space or TAB delimited columns. columns: VLAN ID: numeric value, 0 means no vlan MAC address: string, resolving with L3AddressResolver as MAC_ADDR Interface: interface name, e.g. eth3 (or interface id, e.g. 103) empty lines and commented out lines starts with '#' are allowed.
