Chapter 7. IBM 8285 Configuration
This chapter provides information on how to configure 8285 Classical IP devices and LAN Emulation. ELAN parameters are also listed in this chapter, as well as configuration instructions to troubleshoot the LANE.
7.1 Configuring Classical IP
To allow the 8285 ATM Control Point to communicate with Classical IP (CIP) devices, it is necessary to configure and enable CIP on it.
7.1.1 Classical IP Parameters
The minimal set of parameters you will need in order to configure CIP are:
ATM address | This is the | |
| switch′s CIP interface. This address is comprised of five | |
| basic parts: | |
| 1. | ATM network prefix (bytes |
| 2. | ATM cluster number(ACN) (byte 12) |
| 3. | ATM hub number (AHN) (byte 13) |
| 4. End station identifier (ESI) (bytes | |
| 5. | ATM selector (byte 20) |
ARP server | The ATM address of the ARP server with which to register. | |
| The ARP server will be used for resolving CIP IP | |
| addresses in to ATM addresses. | |
IP address | The IP address assigned to the switch. This must be | |
| unique. | |
Subnet mask | The mask used to allocate the IP address bits. Must | |
| match the mask used by the default gateway. | |
Default gateway | The address to forward packets to to reach other IP | |
| networks. | |
7.1.2 Configuring a Simple CIP Network
The figures below show a simple CIP network, both physically and logically, comprised of an IBM 8285 Nways ATM Workgroup Switch and an ARP server.
