ATM Address Registration Daemon (ilmid)

Address registration with a switch is controlled by ilmid. When an ATM interface is brought up at boot time, ilmid is also started. ilmid then begins an exchange of messages with the switch: relaying local address information (the 7 octet ESI and selector) to the switch and receiving the 13 octet network prefix information from the switch.

The default local address that is registered with the switch at boot time consists of the network prefix provided by the switch, the MAC address assigned to the local interface, and the default selector for that interface (usually 0). Additional addresses are registered in two different ways. aarsetup(1M) and lanesetup(1M) register additional local addresses that may appear in aarconfig(4) and laneconfig(4), respectively. You can also use atmreg(1M) to register addresses, un-register addresses, and check the status of any address.
