Figure 3-1 ILMI Auto-Configuration Examples
Example 1
In this example, the ANIM installed in slot 1 of the 9A656-04 is an ANIM-21/3. This ANIM
provides 3 OC-3 (155 Mbps) switched ports that use Multimode fiber optic cabling. Port one
is connected to an Ethernet to ATM bridge. Ports 2 and 3 are connected to other ATM
switches.
The Ethernet to ATM LEC provides Ethernet users with access to the ATM backbone that the
SmartSwitch 9500 is a part of. In this example, the bridge is a Cabletron Systems
SmartSwitch 2200 (24 port Ethernet Switch) with an HSIM-A6DP (ATM uplink device)
installed. Connected to the SmartSwitch 2200 is a Network Management Station (NMS).
Upon power-up the 9A656-04 automatically configured a default LEC to allow a NMS to
manage the SmartSwitch 9500. The LEC resides on the i960 host processor as shown in
Figure 3-1 . The HSIM-A6DP has been configured to use UNI 3.1 only for signalling,
therefore ILMI has set port 1 of the ANIM to use this Signalling stack. Since the HSIM-A6DP
is an ATM access device, it is running a UNI 3.1 user side Signalling stack, and the 9A656-04
is running a UNI 3.1 network side Signalling stack.
NOTE
The In-Band Management LEC will respond to management requests from any
interface on the system. The NMS described in this definition is only an example of
how this function can work.
