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.
1-4

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
information:
/VLAN/SHOW/VLAN
Virtual LAN Information: VLAN VLAN IP Network Admin Operation Port
ID Description Address Status Status Membership ==== =============== ========== ====== ========= ========== 1 Default VLAN(#1 1.1.1.1 ENABLE ACTIVE 1-16
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

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.

ATM Commands

This chapter contains the ATM command set for the FORMULA 8200 with ATM uplink. Each command is explained, and any applicable arguments and related commands are shown.

How Commands are Organized

FORMULA 8200 switch commands are arranged in a hierarchy of menus. The main menu contains a list of commands. Many of these commands, in turn, have commands or submenus under them.
To display the main menu, type display appears:
== MAIN MENU == ? ALIAS ALLCMD [ATM] [BOOT] [CONSOLE] [ELOG] [ETHERNET] EXIT [FDDI] [FILE] [INET] LOOKUP [MODE] [PORTSERV] REBOOT [SNMP] [SYSTEM] [TFTP] TOP UP [VBRIDGE] [VLAN] [TRACE] / >
? at the prompt. The following
2-1

Entering Commands

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.
2-2
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:
vcip
Aliases are listed with each command description throughout the rest of this chapter.

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)
Asynchronous A method of transmission in which the time intervals between
ATM layer The 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 point On 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.
