Example 1
In this example, the ANIM installed in slot 1 of the 9A686-04 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 Enterasys 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 9A686-04 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 9A686-04
is running a UNI 3.1 network side Signalling stack.
The In-Band Management LEC will respond to management requests from any
NOTE
interface on the system. The NMS described in this definition is only an example of
how this function can work.
