====== How to Specify an ATM Address ======


Depending on whether you’re using ILMI and the LANE services, you may have to specify
one or more ATM addresses when installing the adapter drivers. The ATM address is 20 bytes
in length and is specified as 40 hexadecimal characters. The logical components of an ATM
address are:

  * The switch prefix, consisting of the first 13 bytes, which is typically the same for all ports on a single switch. For example:- **47000580ffe1000000f2150f5b**

  * The end system identifier (ESI), consisting of bytes 14 through 19, which usually is the six-byte hardware MAC address of a particular adapter card. For example:- **002048102aef**

  * The selector byte, the last byte of the ATM address. For example:- **0a**

The following is a sample of the entire ATM address:- **47000580ffe1000000f2150f5b002048102aef0a**


If you are specifying the address in NetWare, Windows NT, or Windows 95, you can use periods to separate the logical components of the address:- **47000580ffe1000000f2150f5b.002048102aef.0a**


The periods used in the sample address above are included to make the address easier to read.
Their use is not required, and they can be placed at irregular intervals as frequently as every
byte.
