This chapter discusses the initial configuration of the LightStream 1010 ATM switch processor (ASP) and includes the following sections:
The LightStream 1010 ATM switch defaults to a working configuration suitable for most networks. However, you might need to customize the configuration for your network.
Although some software configuration examples are provided, this chapter does not provide complete software configuration information. Refer to the LightStream 1010 ATM Switch Software Configuration Guide for complete software configuration information and the LightStream 1010 ATM Switch Command Reference publication for command syntax.
Complete all the interface and power connections described in the LightStream 1010 ATM Switch Hardware Installation Guide and the port adapter module (PAM) connections described in the LightStream 1010 ATM Switch PAM Installation Guide before you begin to configure the switch.
You can configure the LightStream 1010 ATM switch from a direct console connection to the console port or remotely through the Ethernet interface on the ASP.
If you are using a direct console connection, configure your terminal emulation program for 9600 baud, 8 data bits, no parity, and 1 stop bit.
If you are using the Ethernet interface, you need to assign an IP address to the Ethernet interface. The Ethernet interface allows multiple simultaneous Telnet sessions or Simple Network Management Protocol (SNMP) network management for the switch. Ethernet interface configuration instructions are described later in this chapter in the section "Configuring the Ethernet Interface."
Before you power on the system, make sure you have:
All configuration tasks are performed from your terminal emulation program window.
Power on your console and LightStream 1010 ATM switch. Messages similar to the following appear in your terminal emulation program window:

The LightStream 1010 ATM switch should now be operating correctly and transferring data. To confirm that the hardware and software installation and configuration procedures were successful, refer to the next chapter "Checking the ASP Installation."
You can remotely configure the LightStream 1010 ATM switch through the Ethernet interface, but first you must configure an IP address on the Ethernet interface so that it is reachable. There are two ways to configure the Ethernet interface: manually from the command-line interface (CLI) or automatically from a BOOTP server.
Before you begin to manually configure the Ethernet interface, obtain the IP address and subnet mask.
Take these steps:
| Step | Command | Description |
|---|---|---|
| 1 | Switch> enable Switch# | Enter privileged EXEC mode.
|
| 2 | Switch# configure terminal Switch(config)# | Enter global configuration mode.
|
| 3 | Switch(config)# interface eth 2/0/0 | Enter interface configuration mode on Ethernet interface 2/0/0 (the Ethernet port on the ASP). |
| 4 | Switch(config)# ip address ipaddress subnetmask | Enter the IP address and subnet mask for the Ethernet interface. |
| 5 | Switch(config)# line vty 0 4 | Enter line configuration mode for virtual terminal connections. Commands entered in this mode control the operation of telnet sessions to the LightStream 1010 ATM switch. |
| 6 | Switch(config-line)# password password | Enter a password for telnet sessions. |
| 7 | Switch(config-line)# end Switch# | Return to EXEC mode. |
You can set up the LightStream 1010 ATM switch to retrieve its Ethernet IP address from a BOOTP server. Add the MAC and Ethernet IP addresses to the BOOTP configuration file on the BOOTP server. This configuration allows the LightStream 1010 ATM switch to use the BOOTP protocol to retrieve an Ethernet 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 on the switch. (This setting is the default for a new switch or a switch without a configuration file.)
Take these steps:
| Step | Command | Description |
|---|---|---|
| 1 | - | Install the BOOTP server code on the workstation (BOOTP server) if it is not already installed. |
| 2 | - | Locate the switch MAC address on the label attached to the front of the switch. |
| 3 | - | Add an entry to the BOOTP configuration file (usually /usr/etc/bootptab) for each switch. Press Return after each entry to create a blank line between each entry. See the following Example BOOTP Configuration File. |
| 4 | Switch> enable Password: Switch# | Enter privileged EXEC mode. |
| 5 | Switch# reload | Reload the LightStream 1010 ATM switch to request the IP address from the BOOTP server. |

Take these steps:
| Step | Command | Description |
|---|---|---|
| 1 | Switch> enable Switch# | Enter privileged EXEC mode. |
| 2 | Switch# clock set hh:mm:ss | Set the current time in military format, where hh:mm:ss is the time in hours, minutes, and seconds. |
| 3 | Switch# configure terminal Switch(config)# | Enter global configuration mode. |
| 4 | Switch(config)# hostname name_string | Enter a system name. |
| 5 | Switch(config)# enable password password | Enter an enable password to restrict configuration changes. Give this password to users permitted to make configuration changes to the LightStream 1010 ATM switch. |
| 6 | Switch(config)# end Switch# | Return to EXEC mode.
|
When you power on the switch for the first time, the ATM interfaces are automatically configured on the physical ports. Private Network-Network Interface (PNNI) and the physical card type are used to automatically derive the ATM interface type, User-Network Interface (UNI) version, maximum virtual path identifier (VPI) and virtual channel identifier (VCI) bits, ATM interface side, and ATM UNI type. Refer to the
LightStream 1010 ATM Switch Software Configuration Guide for more information.
You can copy, delete, and configure files between the onboard Flash memory Single In-Line Memory Module (SIMM), Flash memory cards, and network servers.
The subsections that follow contain information about the memory file system commands:
This section describes some of the commands you can use with the onboard Flash memory SIMM (bootflash) and Flash memory cards.
Enter the pwd privileged EXEC command to determine which file system device you are accessing:
Switch# pwd bootflash
Enter the cd [bootflash: | slot0: | slot1:] privileged EXEC command to move between Flash memory media:
Switch# cd slot0: Switch# pwd slot0 Switch#
Switch# dir -#- -length- -----date/time------ name 1 5393 May 03 1996 15:32:57 startup-config 2 1814648 Jul 15 1996 10:29:34 ls1010-wp-mz.111-3.005 31819888 Aug 20 1996 15:22:21 ls1010-wp-mz.111-3.018 2428436 bytes available (5566956 bytes used) Switch#
Enter the delete privileged EXEC command to mark a file for deletion from any Flash memory media:
Switch# delete ls1010-wp-mz.111-3.005 Switch# dir -#- -length- -----date/time------ name 1 5393 May 03 1996 15:32:57 startup-config 31819888 Aug 20 1996 15:22:21 ls1010-wp-mz.111-3.018 2428436 bytes available (5566956 bytes used) Switch#
 | Caution When deleting files from memory, do not delete all images. If you delete all existing images, you can no longer download any new images. |
To verify that the delete command was successful, enter the dir command.
Switch# squeeze slot0: All deleted files will be removed, proceed? [confirm]y Squeeze operation may take a while, proceed? [confirm]yebESESESESESESESESESESESE SESESZ Switch# dir -#- -length- -----date/time------ name 1 5393 May 03 1996 15:32:57 startup-config 2 1819888 Aug 20 1996 15:22:21 ls1010-wp-mz.111-3.018 6169852 bytes available (1825540 bytes used) Switch#
In this output, the characters indicate the following:
To prevent data loss due to sudden power loss, the "squeezed" data is temporarily saved to another location of Flash memory specifically allocated for that purpose.
The squeeze command operation keeps a log of the functions performed so that if a power failure occurs, the system continues the process when the power resumes. The character "Z" means this log was erased after the successful squeeze command operation.
A Flash memory card shipped as part of a LightStream 1010 ATM switch contains a system image. A Flash memory card ordered as a spare part is blank and must be formatted before use. This section describes how to format a Flash memory card.
Take these steps:
Step 1 Enter the copy flash tftp EXEC command to copy any important files on the Flash memory card to a TFTP server before reformatting the card. The formatting procedure erases all information on the Flash memory card.
Step 2 Insert the Flash memory card into slot 0. (If slot 0 is not available, use slot 1.) Refer to the section "Installing and Removing Flash Memory Cards" in the chapter "Installing the ASP" for more information.
Step 3 Enter the format slot0: (or format slot1:) privileged EXEC command:
Switch# format slot0: All sectors will be erased, proceed? [confirm] Enter volume id (up to 30 characters): MyNewCard Formatting sector 1 Format device slot0 completed Switch#
The new Flash memory card is now formatted and ready to use.
As future releases of Cisco IOS system images become available, you can receive them either as a file booted from a network server, a file on a floppy disk, or a file on a Flash memory card.
The example that follows describes how to use a new image on a Flash memory card in slot 1 in a system that has an old image on a Flash memory card in slot 0, and a default boot image on the onboard Flash memory SIMM.
In the example, there are three files:
You can copy the new image from the new Flash memory card in slot 1 onto the Flash memory card in slot 0 that contains the old image.
The example that follows assumes that the new image fits on the Flash memory card in slot 0, beside the old image. If there is not enough space, use the delete command to mark the files for deletion from the Flash memory card until there is enough room for the new image; however, do not delete the image.old file. Then enter the squeeze command to remove the files marked for deletion from the Flash memory card. If, after you delete the files and use the squeeze command, the two files cannot coexist on the Flash memory card in slot 0, remove the card, then insert the new Flash memory card (with the file image.new) in slot 0. Enter the boot system flash slot0:image.new command to designate the file image.new as the default boot image.
Make sure both Flash memory cards are installed in slots 0 and 1, and power on the switch. To copy bootable images, take these steps:
| Step | Command | Description |
|---|---|---|
| 1 | Switch> enable Password: Switch# | Enter privileged EXEC mode. |
| 2 | Switch# copy slot1:image.new slot0:image.new | |
| 3 | Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)# | Enter global configuration mode. |
| 4 | Switch(config)# no boot system | Disable booting from bootflash. |
| 5 | Switch(config)# boot system flash slot0:image.new Switch(config)# Ctrl-z Switch# | Enable booting from the file image.new on the Flash memory card in slot 0. |
| 6 | Switch# copy running-config startup-config | Save the configuration to NVRAM. |
| 7 | Switch# reload | Reboot the system. When the system reloads, it boots the file image.new from the Flash memory card in slot 0. |
Take these steps:
| Step | Command | Description |
|---|---|---|
| 1 | Switch> enable Password: Switch# | Enter privileged EXEC mode. |
| 2 | Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)# | Enter global configuration mode. |
| 3 | Switch(config)# boot system flash slot0:image.new | Enable booting from the file image.new on the Flash memory card in slot 0. |
| 4 | Switch(config)# config-reg 0x2102 | Disable Break. |
| 5 | Switch(config)# exit | Return to privileged EXEC mode. |
| 6 | Switch# copy running-config startup-config | Save the configuration to NVRAM. |
| 7 | Switch# reload | Reboot the system. When the system reloads, it boots the file image.new from the Flash memory card in slot 0. |
When you enter boot commands, be careful not to insert extra spaces, which influence the way the switch interprets the command. For example, notice the difference in the following commands:
Switch(config)# boot system flash slot0:myfile (correct command) Switch(config)# boot system flash slot0: myfile (incorrect command)
In the first case, the switch boots the file specified (myfile). In the second case, the switch finds the filename field blank and boots the first file on the Flash memory card.
Take these steps:
| Step | Command | Description |
|---|---|---|
| 1 | Switch> enable Password: Switch# | Enter privileged EXEC mode. |
| 2 | Switch# cd slot 0: | Change directories to slot 0. |
| 3 | Switch# pwd slot0 | Verify that you are in the slot 0 directory. |
| 4 | Switch# dir -#- -length- -----date/time------ name 1 1617864 Nov 01 1996 17:01:27 ls1010-wi-mz_111-1 | Display the contents of Flash memory. Note the name of the file you want to copy. In this example, the system image is ls1010-wi-mz_111-1. |
| 5 | Switch# copy flash tftp | Copy a file from Flash memory to a TFTP server. |
| 6 | Enter source filename: ls1010-wi-mz_111-1 | Enter the name of the system image. In this example, the system image is ls1010-wi-mz_111-1. |
| 7 | Enter destination filename [ls1010-wi-m_1.083.bin.Z]: CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC CCCCCCCC | Enter the destination filename. You can accept the default filename in square brackets or enter a new filename. The series of Cs indicates that a checksum verification of the image is occurring after the image has been written to Flash memory. |
| 8 | Address or name of remote host [172.69.1.129]? ! Switch# | Enter the name or address of the remote host. You can accept the default address in square brackets or enter a new address. |
If the software image on your switch was updated or corrupted, you might want to replace the LightStream 1010 ATM switch system software by copying the image from a TFTP server to the onboard Flash memory.
| Step | Command | Description |
|---|---|---|
| 1 | Switch> enable Password: Switch# | Enter privileged EXEC mode. |
| 2 | Switch# cd slot0: | Change directories to slot 0. |
| 3 | Switch# pwd slot0 | Verify that you are in the slot 0 directory. |
| 4 | Switch# copy tftp flash | Copy a file from a TFTP server to Flash memory. |
| 5 | Enter source filename: ls1010-wi-mz_111-1 | Enter the name of the system image. In this example, the system image is ls1010-wi-mz_111-1. |
| 6 | Enter destination filename [ls1010-wi-m_1.083.bin.Z]: | Enter the destination filename. You can accept the default filename in square brackets or enter a new filename. |

A locked block of Flash memory occurs when power is lost or a Flash memory card is unplugged during a write or erase operation. When a block of Flash memory locks, it cannot be written to, erased, or copied from and the operation consistently fails at a particular block location. You can recover from locked blocks by reformatting the Flash memory card with the format command.
| Caution Formatting a Flash memory card to recover from locked blocks causes you to lose existing data. |
When you have completed autoconfiguration and any manual configurations, copy the configuration into nonvolatile random-access memory (NVRAM). If you power off the LightStream 1010 ATM switch before saving the configuration to NVRAM, all manual configuration changes are lost. Enter the copy running-config startup-config privileged EXEC command to save the configuration to NVRAM:
