It is defined at each switch in the network and consists of an 11-byte network address and a 2-byte area identifier, which is further divided in to a 1-byte ATM Cluster Number (ACN), and a 1-byte Hub Number (HN).
This soft copy for use by IBM employees only. Because ATM allows for dynamic registration of resources, signalling processes have been established to provide for initial registration, connection setup, and connection teardown, whether the connection is native ATM, ATM Forum-Compliant LAN Emulation, or Classical IP (CIP).
This soft copy for use by IBM employees only. If the requested endstation is not local, the switch will forward the request to the correct switch based on routing information compiled and maintained by the 8285 ATM Control Point ′ s Topology and Routing Services (TRS) subsystem.
This soft copy for use by IBM employees only. To avoid having to configure the LES ′ s address at each endstation, LANE provides for a Lan Emulation Configuration Server (LECS), which LECs can query for their proper LES address.
This soft copy for use by IBM employees only. CIP Address Registration: Because in CIP there is no function analogous to the LECS in LANE, each endstation must be configured with the ATM address of its ARP server. The ARP client establishes a connection to the ARP server, and notifies it of its IP address and its ATM address.

Please note that the ACN is the same, indicating that both switches are in the same cluster and will therefore communicate using SSI protocols.
This soft copy for use by IBM employees only. To enable connectivity between the switches, we configure an SSI connection between them. This is done using the SET PORT command: 8285> set port 1.13 enable ssi 155000 When setting up your SSI parameters, make certain that you satisfy the following conditions: 1 .

As a result, the LES and BUS on an ELAN use the same ATM address and the CIP interface address may be in conflict with one of the LANE components ′ addresses.

Note There is a well-known restriction that the IP interfaces of the IBM 8285 and the IBM 8260 should not use IP network number 10 because it i s u se d on their internal network. This restriction applies not only to the CIP interface of the IBM 8285 but also to that of the LECs.
