Overview
The 9A656-04 (shown in Figure 1-1) is a 4.5 Gbps, single slot module for the
SmartSwitch 9500 chassis. Up to four ATM Network Interface Modules (ANIMs)
of any type can be plugged into the 9A656-04 to provide front panel connectivity
to the network. Cabletron Systems ANIMs can support up to 622 Mbps of
bandwidth per port. The 9A656-04 switches data between the ANIMs and the Cell
Transfer Matrix (CTM) backplane in the SmartSwitch 9500 chassis. This allows for
high-speed switching of data between modules installed in the same chassis that
connect to the CTM backplane. The CTM provides a dedicated 1.6 Gbps link
between each 9A656-04 module.
Through its distributed switching architecture, the 9A656-04 allows all the
modules in the chassis to appear as a single entity, with a single IP address and a
single ATM address. The individual i960 processors and the CTM backplane
interfaces are transparent to the network manager and management applications.
A fully loaded SmartSwitch 9500 chassis appears as a single switch, with one IP
address, and one ATM address.
The 9A656-04 is fully compatible with the following ATM Forum speciÞcations:
¥ Integrated Local Management Interface (ILMI) 4.0 for autoconÞguration.
¥ UNI v3.0 /3.1 and v4.0 for signalling.
¥ ATM Forum P-NNI 1.0 and IISP 3.0/3.1 routing speciÞcations for establishing
connections between ATM switches.
¥ IETF AToM MIB (RFC 1695) and AToM II MIB.
¥ LANE 1.0 for the management LAN Emulation Client.
