Chapter 1 ATM Network Configuration This chapter : ❑ Lists the key ATM features of the FORMULA 8200 ❑ Shows how to configure the ATM port ❑ Shows how to set parameters for specific ATM functions you want to run (LEC, CIP, PTOP, or trunking) The commands used in this section are also described in Chapter 2, ATM Commands.
Configuring the ATM Port Configuring the ATM Port This section describes the first of a two-part process to configure the ATM network. To configure an ATM port, use the ATM/CONFIG/MODIFY/PORT command to display screen similar to Figure 1-1. /ATM/CONFIG/MODIFY >PORT ATM Port Configuration 1. ATM PVC/SVC Mode (PVC Mode (a), SVC Mode (b)): SVC Mode 2. Signaling Version (3.0(a), 3.1(b)): Uni 3.0 3. ILMI Enable (Enable(a), Disable(b)): Enable 4. ILMI Poll Enable (Enable(a), Disable(b)): Disable 5.
AT-8202 ATM Uplink User’s Guide Table 1-1 ATM Port Configuration Parameters (Continued) Parameter Description ILMI Poll Enable ILMI variables may be polled using this parameter. Options: Enable or disable Default: Enable Scrambling Enable Bit randomization to increase security Options: Enable or disable Default: Enable Timing Mode Clocking is performed by the FORMULA 8200 (local) or by another switch on the network (loop). Options: Local or loop.
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.
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 ID ==== 1 VLAN Description =============== Default VLAN(#1 IP Network Address ========== 1.1.1.1 Admin Status ====== ENABLE Operation Status ========= ACTIVE Port Membership ========== 1-16 2.
Configuring Classical IP Over ATM (CIP) Table 1-2 CIP Configuration Parameters Parameter Description CIP Index Index of this CIP entity IP Address Takes the same IP network number and subnet number of the LIS (logical IP subnetwork) IP Subnet Mask Subnet mask for this LIS entity Description Optional text description of up to 31 characters Admin Status Administrative status. Options: Enable or disable Default: Enable Connection Type Connection type.
AT-8202 ATM Uplink User’s Guide 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.
Configuring the LAN Emulation Client (LEC) /VLAN/SHOW/VLAN Virtual LAN Information: VLAN ID ==== 1 VLAN Description =========== Default VLAN(#1 IP Network Address ========== 1.1.1.1 Admin Status ====== ENABLE Operation Status ========= ACTIVE Port Membership ========== 1-16 Note If an IP address does not exist for this VLAN, enter an IP address for the FORMULA 8200 using the VLAN/CONFIG/VLAN # command. Refer to the FORMULA 8200 User’s Guide for details. 2.

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.
AT-8202 ATM Uplink User’s Guide /ATM/CONFIG/CREATE >PTOP 1 PTOP Configuration 1. PTOP Index: 1 2. PTOP Description (Optional): PTOP Instance 1 3. Admin Status(ENABLE(a),DISABLE(b): ENABLED 4.

Verify that PTOP services have been created by using the ATM/ SHOW/PTOP command.
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.
AT-8202 ATM Uplink User’s Guide To create trunking service: Note Values shown are for example purposes only; replace with values that apply to your own configuration. 1. Verify the existence of the VLANs you wish to configure with trunking by using the VLAN/SHOW/VLAN command. /VLAN/SHOW >VLAN Virtual LAN Information: VLAN ID ==== 1 2 VLAN Description =============== Default VLAN(#1 VLAN 2 IP Network Address ========== 192.48.127.31 1.1.1.

Chapter 2 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 ? at the prompt.
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 [ ] 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.
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.
Command Edit Mode Command Edit Mode The command interface provides a history mechanism similar to the UNIX K-shell history facility, which allows you to automatically display and edit previously typed commands. This feature may help to save time when entering frequently used commands. Entering and Exiting Edit Mode Press [Escape] to invoke edit mode. Once you are in edit mode, your keystrokes no longer display the characters you type. Instead they invoke the edit mode commands listed in Table 2-1.
AT-8202 ATM Uplink User’s Guide ATM Command Descriptions When you enter the ATM command from the main menu, the following display appears: == ATM MENU == [CONFIG] [SHOW] [STATS] [TEST] Each command and its alias is described in the remainder of this chapter.

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) The layer in the ATM model that provides the protocol between packet services and any ATM cell-oriented switching devices.
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.
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) One of the components of LAN emulation, this is the service that resolves MAC and ATM address mappings for LAN emulation clients.
ATM Acronyms and Terms VCC (virtual channel connection) The link set up between any source and destination in the ATM network. VCI (virtual channel identifier) Address or label contained in the ATM cell header to designate the virtual channel within the virtual path on the physical ATM link.
