6.2.2.1 Compliance to the Standards
The IBM 8285 is compliant to the following standard specifications:
•Physical Interface
As to the physical interface, refer to section 6.1.3, ªATM Ports and Cablingº on page 95.
•UNI (User-to-Network Interface)
There are three versions of UNI standardized by The ATM Forum, V3.0, V3.1, and V4.0. The IBM 8285 supports the following UNI versions:
−V3.0
−V3.1
In addition, the 8285 switch supports the dynamic interconnection between UNI V3.0 and V3.1 devices as well. Both SVC and PVC are supported and they can be defined on the same physical port.
•NNI (Network-to-Network Interface)
There are two protocols of NNI standardized by The ATM Forum, IISP (Interim
−IISP
The IISP protocol is called NNI in the IBM campus ATM Switch terminology.
•LANE (LAN Emulation)
There are two versions of LANE standardized by The ATM Forum, V1.0 and V2.0. The IBM 8285 supports the following LANE version and components:
−LANE V1.0 (both IEEE 802.5 and Ethernet/IEEE 802.3 LANE)
-LES (LAN Emulation Server)
-BUS (Broadcast and Unknown Server)
-LEC (LAN Emulation Client) for node management
The LES/BUS function can interwork with an external LECS. To get the LECS address, all of the standardized mechanisms (via ILMI, using the LECS
Note
The order an LEC attempts the mechanisms is also standardized by The ATM Forum and is as follows:
1.Get LECS address via ILMI
2.Use the LECS
3.Use the LECS PVC
