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.

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

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.

Entering Commands
Enter commands by typing selections from each successive menu,
then pressing the Enter key. You can also enter the entire command
at the prompt or you can use an alias; both methods are described in
the section, Command Formats.
Use of Square
Brackets [ ]
Use of Angle
Brackets <>
Some commands in the main menu have square brackets around
them to indicate that the command requires additional parameters.
When you enter one of these commands, a submenu appears that
lists the available parameters.
Note
Do not enter the brackets when you enter the command.
This guide sometimes directs you to enter a command with a
variable that is specific to your environment, such as IP or ATM
addresses. The variables you must supply are enclosed in angle
brackets.
For example, to configure a gateway address, enter:
/INET/CONFIG/ROUTE/ADD <default router address>
where <default router address> can be in the format,
123.123.123.123.
Note
Do not enter the brackets when you enter the command.

Command
Formats
The software allows you to enter commands in three ways:
❑By using the complete command
❑By using a shortcut
❑By using an alias
Separating Command Words
When you enter any command, separat e the command words with a
slash (/). For example:
/ATM/SHOW/CIP
You may also separate commands with spaces.
AT-8202 ATM Uplink User’s Guide
Shortcuts
Use a shortcut by typing the first few characters needed to
distinguish the command from others that start with the same
letters, such as:
/AT/SH/CIP
The shortcut works unless your shortened version is ambiguous,
which results in an error message.
Aliases
An alias is an abbreviated command that can be accessed from
anywhere in the command line interface. For example, the following
alias is equivalent to the
ATM/SHOW/CIP command:

Appendix A
ATM Acronyms and Terms
This appendix lists and defines ATM acronyms and terms used in this
guide. For a more comprehensive list of ATM acronyms, visit the ATM
Forum website at www.atmforum.com.
For other terms commonly used in Allied Telesyn publications, refer
also to the glossary in Allied Telesyn’s website at
www.alliedtelesyn.com.
AAL (ATM adaptation
layer)
AsynchronousA method of transmission in which the time intervals between
ATM layerThe la y er in the ATM model above the physical layer responsible f or:
CIP (classical IP)RFC 1577 specifies how to carry IP datagrams over the ATM network.
The layer in the ATM model that provides the protocol between
packet services and any ATM cell-oriented switching devices. The
services primarily consist of segmentation and reassembly of data
into multiple 48-byte cells.
characters are not required to be equal and signals are sourced from
independent clocks with different frequencies and phase
relationships. Start and stop bits are added to coordinate character
transfer.
cell multiplexing; virtual path identifier and virtual channel
identifier translation; cell header generation and extraction; and
generic flow control.
It specifies the format of the ATM ARP requests and replies over the
ATM AAL5 layer. It also defines the role and the protocol operation
of the ATM ARP server, and the use of ATM ARP to resolve IP
addresses from ATM addresses and ATM VCI values.
RFC 1483 allows the multiplexing of multiple families of PDUs over
the same VCI, and the protocol is identified by prefixing the PDU by
A-1
ATM Acronyms and Terms
an IEEE 802.2 LLC header (called LLC encapsulation). Using CIP, you
can configure hosts and routers within a closed logical IP subnet
(LIS) with the same IP network/subnet number and address mask,
and they communicate with other members of the same LIS over
the ATM network.
Hosts of different IP subnets must communicate via an IP router,
even though they can communicate via a direct VC.
ELAN (emulated LAN)Following the ATM Forum sub-working group LAN emulation
specification, emulated LANs make connection-oriented ATM
networks look like connectionless local area networks.
End pointOn an ATM network, an end station, server, or internetworking
device connected to the network. End points use either a user-tonetwork interface (UNI) for end stations or servers, or a network-tonetwork interface (NNI) for switch-to-switch connections.
IISP (interim interswitch signaling
protocol)
ILMI (interim local
management interface
A standardized signaling protocol to enable switched virtual circuits
(SVCs) between switches in a private ATM network using static
routes. Based on UNI 3.1 with optional support for UNI 3.0.
Integrated Local Managment Interface: An ATM Forum defined
interim specification for network management functions between
an end user and a public or private network and between a public
network and a private network. This is based on a limited subset of
SNMP capabilities.
LANE (LAN emulation)The method used by switching equipment to emulate the
characteristics of shared-media LANs, standardized by the ATM
Forum to allow transparent operation of existing LANs and
protocols across ATM. Facilitates the operation of broadcastoriented, connectionless networks and employes a server to resolve
addresses between Ethernet and ATM systems. Allows for multicast
services for supporting broadcast traffic when needed and MAC
driver interfaces on A TM stations supporting existing protocols such
as IP, APPN, NetBIOS, and IPX.
LEC (LAN emulation
client)
One of the components of LAN emulation, the LEC is an Ethernet
port in a virtual LAN that has its own ATM address.
A-2
In LANE, ARP is used to translate and map the MAC addresses to
ATM addresses. When an end station sends a MAC frame to an LEC,
the LEC finds the ATM address of the destination with the help of
the LAN emulation server (LES) and sets up an ATM virtual
connection to the destination using SVC. The MAC traffic is then
sent as an ALL5 PDU with an LLC encapsulation ov er the established
virtual connection.
AT-8202 ATM Uplink User’s Guide
LECS (LAN emulation
configuration server)
One of the components of LAN emulation, it is the service that
maintains tables of virtual addresses. A given LEC can query this
database for the address of the LAN emulation server (LES) with
which the LEC needs to register.
LES (LAN emulation
server)
MTU (maximum
transmission unit)
NNI (network-tonetwork interface)
One of the components of LAN emulation, this is the service that
resolves MAC and ATM address mappings for LAN emulation clients.
The largest possible unit of data that can be transmitted on a given
physical medium using a given protocol.
An interface connecting private or public switches. A private NNI is
between two private network switches within a building. A public
NNI is between two public switching devices that create a WAN. The
NNI specification can be applied in both switch-to-switch and
network-to-network situations.
PVC (permanent
virtual circuit)
A dedicated connection between DTE devices configured manually
to be used for a single purpose. This is comparable to a leased line
between communicating devices.
PTOP (point-to-point)A communication link between two end objects or computer
systems in a network of computers.
A PTOP connection link or type requires a set up between two or
more parties before end systems can communicate with each other.
RIP (routing
information protocol)
A distance-vector protocol in the IP suite (used by IP and IPX
network-layer protocols) that enables routers in the same
autonomous system to exchange routing information by means of
periodic updates. For RIP, the best path to a destination is the path
with the fewest hops. RIP computes the distance as a metric, usually
the number of hops from the network of origin to the destination.
SVC (switched virtual
circuit)
UNI (user-to-network
interface)
On-demand connection between ATM or Frame Relay source and
destination that lasts only for the duration of the transmission.
Generic term to indicate interfaces to both public or private Frame
Relay or ATM networks. Typically end point devices such as client
workstations, client servers, or ATM routers. The current UNI
specification describes the signaling protocols that let users set up
connections between ATM devices in customers’ equipment or
public carrier equipment. The UNI specification includes support for
SVCs.
VC (virtual circuit)A network service that provides connection-oriented service
regardless of underlying network structure.
VC (virtual channel)A concept used to describe unidirectional transport of ATM cells
associated by a common unique identifier value.
A-3
ATM Acronyms and Terms
VCC (virtual channel
connection)
VCI (virtual channel
identifier)
The link set up between any source and destination in the ATM
network.
Address or label contained in the ATM cell header to designate the
virtual channel within the virtual path on the physical ATM link.
