NAME

ilmid − ATM Address Registration daemon

SYNOPSIS

/opt/SUNWatm/bin/ilmid [ −c ] [ −v ] [ −x ]

DESCRIPTION

The ATM Address Registration daemon communicates with the switch to establish the 20-byte ATM address for the end system. It implements ILMI, which is the Interim Local Management Interface specified in the ATM User Network Specification. It uses the Simple Network Management Protocol (SNMP) for communication between an ATM switch and host.

An ATM address is made up of a 13-byte network prefix, a 6-byte end system identifier (esi), and a 1-byte selector. Currently, the selector byte is not used in the SunATM implementation; it will be 00 in most cases. The network prefix is assigned by the switch and will be used by the switch for routing. The esi is the unique identification of the end system. A good choice for this is often the default MAC address for the interface. Note that SunATM 1.0 hardware boards do not have their own MAC address assigned, so the default will be the system MAC address. SunATM 2.0 boards, however, do have their own MAC addresses, so the default MAC address will be unique to the board. For all Sun products, the MAC address will begin with the octets 08:00:20.

When the ilmi daemon is executed, it first registers the local MAC address for each interface, obtained from the ATM driver, with the switch. Part of the initial registration process involves obtaining the switch prefix, which ilmid reports to the ATM software. It then waits to receive messages from user programs or the switch, and responds to those accordingly.

Additional addresses may be registered in two different ways. aarsetup(1M) and lanesetup(1M) register additional addresses that may appear in aarconfig(4) and laneconfig(4), respectively. There is also a user program, atmreg(1M), that may be used to register and de-register addresses, and also check the status of any address.

OPTIONS

-c Clear address table. Normally, when ilmid is started, it obtains a list of all addresses that were previously registered from the ATM software, and re-registers all of them. Using the -c option instructs ilmid instead to only register the default address for each interface, and clear all other addresses from the ATM software address table.

-v Verbose mode. Print additional information regarding the communication with the switch.

-x Print (to the console) the messages exchanged between the switch and end system in hexadecimal notation.
