The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single link, not throughout the ATM network, because it has local significance only. The arguments vpi and vci cannot both be set to 0; if one is 0, the other cannot be 0. |
ilmi | (Optional) Used to set up communication with the ILMI; the associated vpi and vci values are ordinarily 0 and 16, respectively. |

If you are configuring an ATM network processor module (NPM), the atm aal aal3/4 command is not required. SMDS encapsulation is not supported on the ATM port adapter. |
