Preface
This user’s guide explains how to configure the AT-8202 ATM uplink
port installed in the FORMULA 8200™ switch and optimize its
available services.
Who Should Use This Guide
This guide is designed for you, the network administrator, to set up
and operate the ATM uplink on the FORMULA 8200 switch. You must
be familiar with ATM network administration.
This guide assumes that a FORMULA 8200 with an ATM uplink card is
already installed and is operational in your network.
Some configurations described in this guide require prior setups,
such as VLAN creation. In such cases, this guide will refer you to the
FORMULA 8200 User’s Guide for related procedures.

Signaling Version The FORMULA 8200 supports UNI 3.0 or UNI 3.1. Set this value depending
upon the UNI support on the ATM switch to which you have connected the
FORMULA 8200. Reboot the switch when the setting signaling version changes.
Default: UNI 3.0.
ILMI Enable ILMI provides network management (NMS) between an end-user and a public
or private network. ILMI functions for configuration, status, and control
information about the physical and ATM layer parameters are available for the
ATM interface.

the network (loop).
Options: Local or loop.
Default: local
Now that you have configured an ATM port, you need to select a
service for forwarding data traffic for the ATM end-system
environment. This comprises the second part of your ATM network
configuration process.
The FORMULA 8200 switch ATM uplink module supports the
following ATM end-system services:
❑
Classical IP (see page 1-4)
❑
LAN emulation client (LEC) (see page 1-7)
❑
Point-to-point bridging (PTOP) (see page 1-12)
1-3
Configuring Classical IP Over ATM (CIP)
Configuring Classical IP Over ATM (CIP)
Current classical IP (CIP) over the ATM model allows direct
connections only between nodes that are in the same logical IP
subnet (LIS). IP datagrams must traverse through routers whenever
they go outside IP subnet boundaries, even when the source and
destinations reside in the same ATM cloud.
IP switching is a way of providing high throughput IP packet transfer
over ATM while maintaining full compatibility with existing IP
networks and applications. IP switching dynamically selects
application traffic that is likely to have long sessions for IP switching,
while using conventional IP routing for low bandwidth application
data.
Y ou can configure up t o 16 CIP connections for every FORMULA 8200
switch.
Note
When using CIP, make sure that the ATM port is configured for SVC
mode.
T o c onfigure CIP par ameters f or an ATM service, you need to perform
the following procedures in sequence:
1. Create a VLAN with a valid IP address, using the command,
CONFIG/VLAN #. Refer to the FORMULA 8200 User’s Guide for the
VLAN/
procedures.
2. Create a CIP service.
3. Set the connection type.
4. Set the following values:
❑ The VCI value if it is a PVC connection
❑ The ARP server ATM address if it is an SVC connection
5. Define an IP address and subnet mask for this CIP service.
The CIP’s IP address must be on a different subnet than the
VLAN’s IP address.

6. Save the CIP configuration
AT-8202 ATM Uplink User’s Guide
To configure CIP services:
1. Use the VLAN/SHOW/VLAN command to verify that a valid IP
address exists.
The
VLAN/SHOW/VLAN command displays the following

2. Create the CIP service using the
<CIP Index> command.
ATM/CONFIG/CREATE/CIP
The valid CIP index values are from 0-15.
A sample screen is shown in Figure 1-2. Table 1-2 provides a
description of each parameter.
/ATM/CONFIG/CREATE > CIP 7

Enter Selection, 0 to save the Modification or ‘q’ to Quit: 2
4. Enter the IP address. The IP address for this CIP service must exist on a different
connected subnet other than the VLAN on the target switch.
5. Enter the subnet mask.
6. Enter the connection type (PVC or SVC). Enter
A for PVC or B for SVC.
7. Define the VCI value if your Step 6 entry is PVC;
or

8. Keep the default value for MTU size.
9. Set the RIP mode.
10. Enter
0 to save the configuration.
Note
To connect two switches for CIP service, you must configure the other
switch with a similar configuration. Also, both subnets and VCIs must
be identical on both switches. The CIP index, however, does not need
to be the same on both switches.
Configuring the LAN Emulation Client (LEC)
You can configure the FORMULA 8200 switch as a LAN emulation
client (LEC) within an emulated LAN (ELAN) environment. An LEC is a
type of virtual port that performs data forwarding, address
resolution, and other control functions over ATM when attached to a
bridge group on the switch. The LEC provides the MAC-level
emulated Ethernet IEEE 802.3 service interface to higher-level
software. The LEC uses the ATM Forum-specified signaling and LAN
emulation control protocols to establish switched virtual
connections (SVCs) with other LECs across ATM.
AT-8202 ATM Uplink User’s Guide
For detailed information on the LEC, refer to the ATM Forum
specification, LAN Emulation Over ATM (v1.0).
To configure LEC parameters for an ATM service, you will need to:
❑ Configure a LEC service
❑ Define a VLAN ID or number
❑ Set the port service for binding an ATM port
Note
Make sure that the ATM port is configured for SVC mode and that the
ILMI is enabled.
You can configure up to 16 LAN emulation clients (LECs).
To configure an ATM LEC service:
1. Verify that a valid IP address exists by using the VLAN/SHOW/
VLAN command.
The
VLAN/SHOW/VLAN command displays the following
information:

Configuring Point-to-Point (PTOP)
Configuring Point-to-Point (PTOP)
PTOP bridging enables setup between two or more parties to share a
virtual channel connection (VCC) using either a permanent virtual
connection (PVC) or a switched virtual connection (SVC). This feature
supports up to 16 PTOP connections. Only one VLAN and one VCI at a
time can participate in a PTOP configuration.
To configure PTOP parameters for an ATM service, you need to:
❑ Set the PTOP instance ID.
❑ Set the VCI value.
❑ Set the port service for binding an ATM port.
A VLAN with a valid IP address must exist prior to configuring PTOP.
To configure PTOP:
Note

Configuring Trunking
Configuring Trunking
Trunking allows VLANs to be extended across multiple switches.
Trunk ports encapsulate the bridged frames within a proprietary
frame. The proprietary frame includes information required to
reproduce the frame on the opposite end of the trunk and to
maintain VLAN separation.
Without trunking service, different groups of VLANs must use two
separate virtual circuits (VCs) across an ATM interface. With trunking,
different groups of VLANs can share the same ATM VC, as shown in
Figure 1-3.

Note
For ATM interfaces, a trunking service and a PTOP service can run
simultaneously on the same VLAN.
