Configuring the Route Processor for the Catalyst 8540 and Using Flash Memory Cards

The RP resides in slot 4.

• Check that the system is set for the correct AC power voltages.

Refer to the appendix "System Chassis Specifications" in the Catalyst 8540 Chassis Installation Guide for correct AC power voltages.

• Connect the cables to the system.

• Configure your terminal emulation program for 9600 baud, 8 data bits, no parity, and 1 stop bit.

All configuration tasks are performed from your terminal emulation program window.

1. Power up your console and Catalyst 8540 campus switch router.

Messages appear in your terminal emulation program window.

The Catalyst 8540 campus switch router should now be operating correctly and transferring data. To confirm that the hardware and software installation and configuration procedures were successful, refer to the chapter "Checking the Component Installation" in the Catalyst 8540 Campus Switch Router Processor and Line Module Installation Guide.

Before you begin to manually configure the RP interface, obtain its IP address and IP subnet mask.

Step	Command	Description
1	Router> enable Router#	To enter enable mode the first time, just enter enable. The # prompt indicates you are in enable mode.
2	Router# enable-password password	Set the enable password.
3	Router# show interface ethernet0	Issue the show interface ethernet0 command to discover the switch router's MAC address. The console cable must be connected to the system.
4	Router# configure terminal Router(config)#	Enter global configuration mode. You can also abbreviate the command to config t. The prompt Router(config)# indicates that you are in global configuration mode.
5	Router(config)# interface ethernet0	Enter interface configuration mode on the Ethernet interface Ethernet0 (the management port on the RP).
6	Router(config-if)# ip address ipaddress subnetmask	Enter the IP address and IP subnet mask for the Ethernet interface.
7	Router(config-if)# exit Router(config)#	Return to global configuration mode.
8	Router(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 Catalyst 8540 campus switch router.
9	Router(config-line)# password password	Enter a password for Telnet sessions.
10	Router(config-line)# Ctrl-Z Router#	Return to privileged EXEC mode.

The switch router 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.)

Step	Command	Description
1	---	Install the BOOTP server code on the workstation (BOOTP server) if it is not already installed.
2	---	Note the switch router's MAC address, which you can find by issuing a show interface ethernet0 command.
3	---	Add an entry to the BOOTP configuration file (usually /usr/etc/bootptab) for each switch. Press Enter after each entry to create a blank line between each entry. (See the following example BOOTP configuration file.)
4	Router> enable Password: Router#	Enter privileged EXEC mode.
5	Router# reload	Reload the Catalyst 8540 campus switch router to request the IP address from the BOOTP server.

• Enable password: a less secure, or nonencrypted, password.

• Enable secret password: a very secure, encrypted password.

By setting an encrypted password, you can prevent unauthorized configuration changes.

The enable and enable secret password functionality is available in all Cisco IOS releases for the Catalyst 8540 campus switch routers. When you are running from the boot ROM, the enable password might be used, depending on your ROM level.

The passwords should be different for maximum security. If you enter the same password for both during the setup script, the system will accept it, but you will receive a warning message indicating that you should enter a different password.

An enable password can contain any number of uppercase and lowercase alphanumeric characters; an enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters. In both cases, a number cannot be the first character. Spaces are also valid password characters; for example, "two words" is a valid password. Leading spaces are ignored; trailing spaces are recognized.

Step	Command	Description
1	Router># enable Router#	To enter enable mode the first time, enter enable. The # prompt indicates you are in privileged EXEC mode.
2	Router# configure terminal Router(config)#	Enter global configuration mode. You can also abbreviate the command to config t. The prompt Router(config)# indicates that you are in global configuration mode.
3	Router (config)# enable-password password	Set the enable password.
4	Router(config)# enable secret new password	Enter an enable secret password. Once set, a user must enter the enable secret password to gain access to global configuration mode.

Step	Command	Description
1	Router# clock set hh:mm:ss month day year	From privileged EXEC mode, set the current time in 24-hour format, in which hh:mm:ss is the time in hours, minutes, and seconds. For example, 1:30 p.m. is 13:30:00 in 24-hour format.
2	Router# configure terminal Router(config)#	Enter global configuration mode.
3	Router(config)# hostname name_string	Enter a system name. In this example, we set the hostname to "8540," which is the hostname used throughout this guide.
4	8540(config)# enable password password	Enter an enable password to restrict configuration changes. Give this password to users permitted to make configuration changes to the Catalyst 8540 campus switch router.
5	8540(config)# end 8540#	Return to privileged EXEC mode.

e	This special location has been erased (which must be performed before any write operation).
b	The data about to be written to this special location was temporarily copied.
E	The sector temporarily occupied by the data was erased.
S	The data was written to its permanent location in Flash memory.

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" indicates this log was erased after the squeeze command operation was successfully completed.

To format a Flash memory card, follow these steps:

Step 1 To copy any important files on the Flash memory card to a TFTP server before reformatting the card, enter the copy flash tftp EXEC command.

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.)

For more information, refer to the section "Installing and Removing Flash Memory Cards" in the Catalyst 8540 Campus Switch Router Processor and Line Module Installation Guide.

Step 3 Enter the format slot0: (or format slot1:) privileged EXEC command:

8540# format slot0:
All sectors will be erased, proceed? [confirm]
Enter volume ID (up to 30 characters): MyNewCard
Formatting sector 1
Format device slot0 completed

The new Flash memory card is now formatted and ready to use.

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.

In the example, there are three files:

• The new image on the Flash memory card in slot 1 is image.new.

• The old image on the Flash memory card in slot 0 is image.old.

• The bootable image on the onboard Flash memory is image.boot.

Step 1 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.

Step 2 Enter the squeeze command to remove the files marked for deletion from the Flash memory card.

Step 3 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.

Step 5 Make sure both Flash memory cards are installed in slots 0 and 1, and power up the Catalyst 8540 switch router.

Step	Command	Description
1	8540> enable Password: 8540#	Enter privileged EXEC mode.
2	8540# copy slot1:image.new slot0:image.new	Copy the file image.new in slot 1 to the Flash memory card in slot 0 only if there is enough memory space for the two images to coexist.
3	8540# configure terminal 8540(config)#	Enter global configuration mode.
4	8540(config)# no boot system	Disable booting from bootflash.
5	8540(config)# boot system flash slot0:image.new 8540(config)# Ctrl-Z 8540#	Enable booting from the file image.new on the Flash memory card in slot 0.
6	8540# copy running-config startup-config	Save the configuration to NVRAM.
7	8540(config)# reload	Reboot the system. When the system reloads, it boots the file image.new from the Flash memory card in slot 0.

Step	Command	Description
1	8540# cd slot 0:	From privileged EXEC mode, change the Flash device to slot 0 on the Flash memory card.
2	8540)# pwd slot0	Verify that you are in the slot 0 directory.
3	8540# show flash all # cat8540c-in-mz_111-1	If you do not already know it, note the exact spelling of the system image filename in Flash memory. Use the show flash all command to display the contents of Flash memory. Note the name of the image file you want to copy. In this example, the system image is named cat8540c-in-mz_111-1.
4	8540# copy flash tftp:	Copy a file from Flash memory to a TFTP server. Be sure to include a colon at the end of the tftp parameter as shown in this example.
5	Enter source filename: cat8540c-in-mz_111-1	Enter the name of the system image.
6	Enter destination filename: [cat8540c-in-mz_111-1]:	Enter the destination filename. You can accept the default filename in square brackets or enter a new filename.
7	Address or name of remote host: [172.68.16.129]? 8540#	Enter the domain name or IP address of the TFTP server. You can accept the default address in square brackets or enter a new address.

Before you begin, be sure to insert a properly formatted Flash memory card into slot 0.

Step	Command	Description
1	8540# cd slot0:	From privileged EXEC mode, change the Flash device to slot 0 on the Flash memory card.
2	8540)# pwd slot0	Verify that you are in the slot 0 directory.
3	8540# copy tftp flash	Copy a file from a TFTP server to Flash memory.
4	Enter source filename: cat8540c-in_mz_111-1	Enter the name of the system image.
5	Enter destination filename: [cat8540c-in-mz_111_1]:	Enter the destination filename. You can accept the default filename in square brackets or enter a new filename.
6	5746016 bytes available on device slot0, proceed? [confirm] y	Enter y if enough space exists in Flash memory for the file you want to copy.
7	Address or name of remote host: [172.68.16.129]?	Enter the domain name or IP address of the TFTP server. You can accept the default address in square brackets or enter a new address.

To save your configuration changes to NVRAM so that they are not lost during a power cycle or power outage, follow these steps:

Step	Command	Description
1	8540# show running	Check the settings you have configured so far.
2	8540# copy running startup	If the settings are what you want, save the configuration to NVRAM.
3	8540# Ctrl-Z 8540>	Return to user EXEC mode.
