That is basically all that is required to configure a simple ATM CIP network.
7.2 Configuring LAN Emulation
The IBM 8285 Control Point can provide the
7.2.1 8285 LAN Emulation Functions Overview
The IBM 8285 Control Point can provide the
7.2.2 LAN Emulation Parameters
The only parameters you will need in order to configure LAN Emulation functions are:
•ATM Address
This is the
1.ATM network prefix (bytes
2.ATM cluster number (ACN) (byte 12)
3.ATM hub number (HN) (byte 13)
4.End station identifier (ESI) (bytes
5.ATM selector field (SEL) (byte 20)
In the IBM 8285 there is only one command, SET DEVICE ATM_ADDRESS, to define the ATM address and it is to configure the ATM address for the CIP interface. The addresses of LAN Emulation components are automatically assigned based on the CIP interface address by changing the selector field of it. Table 35 on page 132 shows the
