Configuring the LightStream 1010 ATM Switch

This chapter discusses the initial configuration of the LightStream 1010 Asynchronous Transfer mode (ATM) switch. Because the LightStream 1010 offers true plug-and-play operation, most users may not need to perform any of these procedures.

The LightStream 1010 is shipped with the ATM address autoconfigured to an address assigned by Cisco Systems. This feature lets the switch automatically configure attached end systems using the Interim Local Management Interface (ILMI) protocol and automatically establishes itself as a node in a single-level Private Network-Network Interface (PNNI) routing domain.

Note The default software image for the LightStream 1010 contains only the Interim Interswitch Signaling Protocol (IISP) for routing. This is suitable for small networks that do not require the sophistication of the PNNI protocols. A separate orderable image contains both PNNI and IISP. The PNNI protocol provides the route dissemination mechanism for complete plug-and-play capability.

The ILMI and PNNI protocols, when used with such IP address autoconfiguration mechanisms as BOOTP, allow the LightStream 1010 to be entirely self-configured. Through network management applications and the text-based command line interface (CLI), the switch's network operator has the capability, if desired, to configure and customize all aspects of the operation of the switch.

An IP address must be assigned to allow up to eight simultaneous Telnet sessions to connect to the switch or to use Simple Network Management Protocol (SNMP) network management for the switch. The Ethernet IP address can be assigned either manually or by a BOOTP server. See the section "Configuring Ethernet IP Interface Parameters."

Note If your Telnet station or SNMP network management workstation is on a different network from the switch, a static routing table entry must also be added to the routing table. Use the configure ip route command to set the static routing table entry.

For definitions of all commands discussed in this chapter, refer to the publication LightStream 1010 ATM Switch Command Reference.

The following sections describe how to initially configure the LightStream 1010:

Before You Begin

You may need the following information before you can begin your LightStream 1010 configuration if you want to configure some additional features:

Media Access Control (MAC) address of the Ethernet port if you want to configure a BOOTP server to inform the switch of its Ethernet IP address and mask
ATM address assigned by your system administrator if you want to configure a new ATM address for the switch (an autoconfigured ATM address is assigned by Cisco Systems)
IP address of the Ethernet port if not using BOOTP
Netmask address if you want to configure the Ethernet port on the ATM Switch Processor (ASP)
Broadcast address if you want to configure the Ethernet port on the ASP

To help configure your switch you should have already completed the worksheets in the section "Port Configuration Worksheets" in the appendix "Configuration Worksheets."

Note Complete all interface and power connections described in the chapter "Installing the LightStream 1010 ATM Switch" before beginning to configure the switch.

Powering Up Your System

Before powering up your system, check for correct AC power voltages. See the appendix "System Specifications" for correct AC power voltages.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."

Warning Care must be given to connecting units to the supply circuit so that wiring is not overloaded. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."

Now you can safely power up your system by flipping the power switch(es) on the power supply(ies).

Verifying Installed LightStream 1010 Software and Hardware

When you first power up your console and LightStream 1010, a screen similar to the following appears:

The LightStream 1010 should be operating correctly and transferring data. To confirm that the hardware and software installation and configuration procedures were successful, see the chapter "Confirming the Installation."

BOOTP Server Configuration

The LightStream 1010 Ethernet IP address can be automatically assigned using the BOOTP protocol by adding the MAC and IP addresses of the Ethernet port to the BOOTP server configuration file. When the switch boots, it automatically retrieves the IP address from the BOOTP server.

The switch performs a BOOTP request only if the current IP address is set to 0.0.0.0. (This setting is the default for a new switch or a switch that has had its configuration file cleared using the erase startup-config command.)

To allow your LightStream 1010 to retrieve its IP address from a BOOTP server, find the MAC address label attached to the front of the switch. Add that MAC address to the BOOTP configuration file on the BOOTP server. The following tasks provide an example of creating a BOOTP server configuration file:

Task	Command
Install the BOOTP server code on the workstation if it is not already installed.	None
The switch MAC address is printed on a label attached to the front of the switch.	None
Add an entry in the BOOTP configuration file (usually /usr/etc/bootptab) for each switch. Press Return after each entry to create a blank line between each entry. Figure 6-1 is an example of a server BOOTP configuration file.	None
Restart the LightStream 1010 to automatically request the IP address from the BOOTP server.	Restart

ATM Address Configuration

The LightStream 1010 ATM switch is autoconfigured with an ATM address using a hierarchical addressing model similar to the Open System Interconnection (OSI) network service access point (NSAP) addresses. PNNI uses this hierarchy to construct ATM peer groups.

Note The most important rule in the addressing scheme is to maintain the uniqueness of the address across very large networks.

Autoconfigured ATM Addressing Scheme

During the initial startup, the LightStream 1010 generates an ATM address using the defaults shown in Figure 6-2.

Figure 6-2: ATM Address Format

Authority Format Identifier (AFI)--1 byte
Cisco-specific International Code Designator (ICD)--2 bytes
Cisco-specific information--4 bytes
Unique MAC address--6 bytes (used to distinguish multiple switches)

Note In the address, the first 13 bytes comprise a switch prefix used by ILMI in assigning addresses to end systems connected to user-to-network interface (UNI) ports.

MAC address of the switch--6 bytes (used to distinguish multiple end systems attached to the same switch)

Note Both MAC address fields are the same.

Selector--1 byte

The switch's ATM address uses a hierarchical addressing model similar to the Open System Interconnect (OSI) network service access point (NSAP) addresses. PNNI uses this hierarchy to construct ATM peer groups. ILMI uses the first 13-bytes of this address as the switch prefix that it registers with end systems.

Default Address Format Features and Implications

Using the default address format has the following features and implications:

Switches other than LightStream 1010 ATM Switches can be manually configured using the Cisco autoconfigured address format. This allows them to be used in a single-level PNNI routing domain consisting primarily of autoconfigured LightStream 1010 ATM switches. A globally unique MAC address must be used to generate the ATM address.
The same MAC address can be used for bytes 8 through 13 and bytes 14 through 19.
This address assignment format is relatively flat. To achieve scalable hierarchical network organization the ATM routing addresses will need to be changed when connecting to a large ATM network with multiple levels of PNNI hierarchy.
Summary addresses less than 13 bytes long should not be used with autoconfigured ATM addresses. Other switches with autoconfigured ATM addresses matching the summary may exist outside the default peer group.

Manually Setting the ATM Address

To configure a new ATM address that replaces the previous ATM address when running IISP software only, see the section "Configure the ATM Address" in the chapter "Configuring ILMI" in the LightStream 1010 ATM Switch Software Configuration Guide.

To configure a new ATM address that replaces the previous ATM address and generates a new PNNI node ID and peer group ID, see the section "Configure PNNI Node" in the chapter "Configuring PNNI" in the LightStream 1010 ATM Switch Software Configuration Guide.

Multiple addresses can be configured for a single switch and this configuration can be used during ATM address migration. ILMI registers end systems with multiple prefixes during this period until an old address is removed. PNNI automatically summarizes all of the switch prefixes in its reachable address advertisement.

If operation with ATM addresses other than the autoconfigured ATM address is desired, use the atm address command to manually assign a 20-byte ATM address to the switch. The atm address command address_template variable can be a full 20-byte address or a 13-byte prefix followed by ellipsis (...). Entering the ellipsis will automatically add one of the switch's 6-byte MAC addresses in the ESI portion and 0 in the selector portion of the address.

Caution ATM addressing may lead to conflicts if not configured correctly. The correct address must always be present. For instance, if you are configuring a new ATM address, the old one must be completely removed from the configuration.

To set the ATM address manually, refer to the LightStream 1010 ATM Switch Software Configuration Guide.

Configuring the Interfaces

When the switch is powered on initially without any previous configuration data, the ATM interfaces are automatically configured on the physical ports. ILMI and the physical card type are used to automatically derive the ATM interface type, UNI version, maximum virtual path identifier (VPI) and virtual channel identifier (VCI) bits, ATM interface side, and ATM UNI type.

Default ATM Interface Configuration Without Autoconfiguration

If ILMI has been disabled or if the connecting end node does not support ILMI, the following defaults are assigned to all interfaces:

ATM interface type = UNI
UNI version = 3.0
Maximum VPI bits = 8
Maximum VCI bits = 14
ATM interface side = network
ATM UNI type = private

The following PAM types have specific defaults assigned:

OC3 PAM:

Framing = sts-3c
Clock-source = free-running
Synchronous Transfer Signal (STS) -stream scrambling = on
Cell payload scrambling = on

OC12 PAM:

Framing = sts-12c
Clock-source = free-running
STS-stream scrambling = on
Cell payload scrambling = on

DS3 PAM:

Framing = cbit-adm
Cell payload scrambling = off
Clock-source = free-running
Line build out (LBO) = short
Auto-ferf on loss of signal (LOS) = on
Auto-ferf on out of frame (OOF) = on
Auto-ferf on red = on
Auto-ferf on loss of cell delineation (LCD) = on
Auto-ferf on alarm indication signaling (AIS) = on

E3 PAM:

Framing = g.751 plcp
Cell payload scrambling = on
Clock-source = free-running
Auto-ferf on LOS = on
Auto-ferf on out of frame (OOF) = on
Auto-ferf on red = on
Auto-ferf on LCD = on
Auto-ferf on AIS = on

You can accept the default ATM interface configuration or overwrite the default interface configuration using the CLI commands. These commands are described in the LightStream 1010 ATM Switch Software Configuration Guide, which provides detailed ATM interface configuration tasks.

Configuring Ethernet IP Interface Parameters

Three different IP addresses may be configured on the LightStream 1010. The IP address for the Ethernet port, classical IP over ATM, and a LAN emulation (LANE) client. Each IP address is configured using one of the following methods:

Ethernet port--May be configured either from the BOOTP server or using the interface ethernet 2/0/0 ip address command
Classical IP over ATM--See the section "Configuring Classical IP Over ATM" in the chapter "Configuring an ATM Network"
LANE client--See the section "Configuring LAN Emulation Client Example" in the chapter "Configuring an ATM Network"

Note These IP connections are used only with network management.

Configure the interface to communicate with the switch central processor unit (CPU) (interface 2/0/0) or Ethernet interface 2/0/0 using the following information as a guide:

Provide the IP address and subnet mask bits for the interface as follows:

IP address

: Internet addresses are 32-bit values assigned to hosts that use the IP protocols. These addresses are in dotted decimal format (four decimal numbers separated by periods) such as 192.17.5.100. Each number is an 8-bit value between 0 and 255. The following is a summary of IP addressing concepts for those who are somewhat familiar with IP addressing.
: The addresses are divided into three classes; the classes differ in the number of bits allocated to the network and host portions of the address.
: The Class A Internet address format allocates the highest 8 bits to the network field and sets the highest-order bit to 0 (zero). The remaining 24 bits form the host field.
: The Class B Internet address allocates the highest 16 bits to the network field and sets the two highest-order bits to 1, 0. The remaining 16 bits form the host field.
: The Class C Internet address allocates the highest 24 bits to the network field and sets the three highest-order bits to 1, 1, 0. The remaining 8 bits form the host field.
: Default: None.
: Action: Enter your Internet address in dotted decimal format for each interface you plan to configure.

Subnet mask bits

: Subnetting is an extension of the Internet addressing scheme, that allows multiple physical networks to exist within a single Class A, B, or C network. The usual practice is to use a few of the far left bits in the host portion of the network address for a subnet field. The subnet mask determines whether subnetting is in effect on a network.
: Internet addressing conventions allow a total of 24 host bits for Class A addresses, a total of 16 host bits for Class B addresses, and a total of 8 host bits for Class C addresses. When you are further subdividing your network (that is, subnetting your network), the number of host addressing bits is divided between subnetting bits and actual host address bits. You must specify a minimum of two host address bits, or the subnetwork could not be populated by hosts. Therefore, the ip address command permits you to specify up to 22 host bits for Class A subnetting, 14 bits for Class B subnetting, and
6 bits for Class C subnetting. Table 6-1 provides summaries of these subnetting parameters.

Table 6-1: Summary of Subnetting Parameters

First Class	First Byte	Network Bits	Host Bits
First Class	First Byte	Network Bits	Max Subnet Bits	Min Address Bits
A	1-126	8	22	2
B	128-191	16	14	2
C	192-223	24	6	2

: Default: 0.

Note Because all zeros in the host field specify the entire network, subnetting with subnet address 0 is illegal and is strongly discouraged.

Define subnet mask bits as a decimal number between 0 and 22 for Class A addresses, 0 and 14 for Class B addresses, or 0 and 6 for Class C addresses. Do not specify 1 as the number of bits for the subnet field. That specification is reserved by Internet conventions.

Configuring the Network Routing

The default software image for the LightStream 1010 will contain only the IISP routing protocol. This will be suitable for small networks that do not require the sophistication of the PNNI protocols. A separate orderable image contains both PNNI and IISP protocols. The PNNI protocol provides the route dissemination mechanism for complete plug-and-play capability.

The following section describes modifications that may be made to the default PNNI or IISP routing configurations:

For detailed descriptions of these routing protocols see the section "ATM Routing" in the chapter "What is the LightStream 1010 ATM Switch?"

Configuring PNNI Connections

The PNNI routing protocol automatically creates peer groups that are a collection of logical nodes, each of which exchanges information with the other members of the group, so that all members maintain an identical view of the group. For example, hellos, database synchronization, and flooding are carried out among members of the same peer group. All members of the same peer group have the same 13-byte PNNI prefix in their ATM address. A peer group can be considered similar to either open shortest path first (OSPF) or IP routing domains, depending on usage.

This peer group configuration information is in the hierarchy database stored within each switch and updated regularly.

The following section will discuss manually configuring two autonomous peer groups to create one single peer group.

Peer Group ID Modification

To manually configure two autonomous peer groups into one, all members of the peer group must have the same peer group ID in their ATM address. The following sections describe the manual PNNI peer-group modification process:

Using show atm pnni node id to Determine Peer-Group ID

Use the show pnni node-id command to determine the peer-group IDs to modify:

Task	Command
Display ATM address prefix	show atm pnni node-id

Example

Switch#show atm pnni node-id
  Node    Node Id
  ----    -------
  1       56:160:47.000000000000000000000000.000000005656.00
Switch#

Using atm address to Manually Change Peer-Group ID

The atm address command assigns a 20-byte ATM address to the switch. See the section "ATM Address Configuration" for a complete description of this command.

Multiple addresses can be configured for a single switch and this can be used during address migration. ILMI would register end systems with multiple prefixes during this period until an old address is removed. PNNI automatically summarizes all switch prefixes in its reachable address advertisement.

To configure the ATM address manually, use the following commands using the no form of this command to disable.

Task	Command
At the privileged EXEC prompt, enter configuration mode from the terminal	configure¹ [terminal]
Change 13 byte ATM prefix in the ATM address to match the desired switch prefix	atm address 13_byte_switch _prefix ...
Delete the old ATM address	no atm address 13_byte_switch_prefix ...
Start PNNI configuration mode	atm router pnni
Disable the node	atm node 1 disable
Enable the node	atm node 1 enable
Restart PNNI to force it to read the new node IDs.	restart pnni

¹ This command is documented in the LightStream 1010 ATM Switch Command Reference publication.

Example

The following steps configure a peer-group ID manually:

Step 1 Adds the ATM address prefix 47.0091.8100.5670.000.0ca7.ce01, (...), and adds the default MAC address as the last six bytes.

Step 2 Deletes the old ATM address prefix.

Step 3 Starts PNNI configuration mode.

Step 4 Disables ATM node 1.

Step 5 Reenables node 1.

Step 6 Restarts PNNI.

Switch(config)#atm address 47.0091.8100.5670.0000.0ca7.ce01...
Switch(config)#no atm address 47.0091.8100.1200.0000.0ca7.ce01...
Switch(config)#atm router pnni
Switch(config)#atm node 1 disable
Switch(config)#atm node 1 enable
Switch(config)#restart pnni

Configuring ATM Routes for IISP or PNNI

Use the atm route command to configure a static route. A static route attached to an interface allows all ATM address prefixes where the static route is a match to be reached through that interface.

Note Two PNNI peer groups may be connected using the IISP protocol. This requires a static route to be configured on the IISP interfaces to allow connections to be setup across the IISP link(s).

Figure 6-3 is an example of the atm route command configuring a static route to the 13-byte-switch-prefix = 47.0091.8100.567.0000.0ca7.ce01 to interface 3/0/0.

Figure 6-3: Example of the atm route Command

Switch(config)#atm route 47.0091.8100.567.0000.0ca7.ce01 atm 3/0/0
Switch(config)#

Configuring the System Information

Although not required, several system parameters should be set as part of the initial system configuration. These system information commands make troubleshooting and configuring the switches easier. To set the system parameters, perform the following tasks in EXEC mode:

Task	Command
Set the system clock.	clock set hh:mm:ss
At the privileged EXEC prompt, enter configuration mode from the terminal.	configure¹ [terminal]
Set the system name.	hostname name_string

¹ This command is documented in the LightStream 1010 ATM Switch Command Reference publication.

Syntax Description

hh:mm:ss--Current time in hours (military format), minutes, and seconds.
name_string--Desired name of the switch.

Configuring SNMP Management

SNMP, an application-layer protocol, facilitates the exchange of Management Information Bases (MIBs) between network devices. SNMP community strings authenticate access to the MIB and function as embedded "passwords."

To manually configure the LightStream 1010 SNMP, refer to the LightStream 1010 ATM Switch Software Configuration Guide. For definitions of all commands discussed in this chapter, refer to the publication LightStream 1010 ATM Switch Command Reference.

Storing the Configuration at Startup

When autoconfiguration and any manual configurations are complete, you should copy the configuration into nonvolatile random-access memory (NVRAM). If you should power off your LightStream 1010 prior to saving the configuration in NVRAM, all manual configuration changes will be lost. Figure 6-4 is an example of the copy running-config startup-config command.

Using ping to Test the Ethernet Connection

After you have configured the IP address(es) for the Ethernet interface, test for connectivity between the switch and a host. The host can reside anywhere in your network. To test for Ethernet connectivity, perform the following tasks:

Task	Command
Test the configuration using the ping command. The ping command sends an echo request to the host specified in the command line.	ping [protocol] {host \| address}

For example, to test Ethernet connectivity from the switch to a workstation with an IP address of 192.34.56.5, enter the command ping 192.34.56.5. If the switch receives a response, a message is displayed as show, in Figure 6-9.

Figure 6-9: Example of ping ip Command

Switch#ping ip 172.20.40.201
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.20.40.201, timeout is 2 seconds:
