This chapter describes how to initially configure the Layer 3 switch routers.
 |
Note You are at Step 2 in the suggested process for configuring your Layer 3 switch router (see Table 2-1). You should have already set up the hardware before proceeding with the initial switch router configurations. |
The following is a review of tasks you should have completed during hardware installation, including starting up the switch router. These tasks must be completed before proceeding with configuring your switch router.
Refer to the Catalyst 2948G-L3 Hardware Installation Guide or the Catalyst 4908G-L3 Hardware Installation Guide for correct power voltages.
Step 2 Connect the cables to the switch router.
Step 3 Connect the console terminal to the switch router.
Step 4 Power on the switch router.
Step 5 Enter CLI configuration mode by answering no when you are prompted to enter the initial dialog:
Would you like to enter the initial dialog? [yes]:no
You see the following user EXEC prompt: Router>
In this step, you can also choose to answer yes and continue to use the configuration menu that is provided.
You can configure your switch router from a direct console connection to the console port or remotely through its management port.
For interface configuration instructions, see the "Configuring the Management Port" section.
For further details on configuring ports and lines for management access, refer to the
Cisco IOS Configuration Fundamentals Configuration Guide .
Your switch router has a console terminal line that you might need to configure. For line configuration, you must first set up the line for the terminal or the asynchronous device attached to it. For a complete description of configuration tasks and commands used to set up your terminal line and settings, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Dial Solutions Configuration Guide.
You can connect a modem to the console port or to the auxiliary port on the switch router. The following settings on the modem are required:
You can configure your modem by setting the DIP switches on the modem or by connecting the modem to terminal equipment. Refer to the user manual provided with your modem for the correct configuration information.
|
Note Because there are no hardware flow control signals available on the console port, the console port terminal characteristics should match the modem settings. |
For further details on configuring ports and modems for management access, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Dial Solutions Configuration Guide.
The Catalyst 2948G-L3 and the Catalyst 4908G-L3 support Xmodem and Ymodem protocols. If all of the system images in the boot flash memory are somehow damaged or erased, you can copy an image from a local or remote computer (such as a PC, UNIX workstation, or Macintosh computer) using the Xmodem or Ymodem protocols. The Xmodem and Ymodem protocols support different speeds of file transfers. The maximum file transfer speed supported is 57600 baud. This functionality primarily serves as a disaster recovery technique where system images are recovered using Xmodem and Ymodem commands on the ROM monitor from the console port on your switch router.
See the "Recovering a System Image Using Xmodem and Ymodem" section.
There are two types of passwords.You can configure both an enable password and an enable secret password. For maximum security, the enable password should be different from the enable secret password.
You will configure passwords in the next section, "Configuring the Management Port."
You can remotely configure the switch router through the management port, but first you must configure an IP address so that the switch router is reachable. You can manually configure the management port interface from the command-line interface (CLI).
|
Note Before you begin to configure the management port interface manually, obtain the switch router's IP address and IP subnet mask. Also make sure the console cable is connected to the console port. |
You can configure the management port from an IP connected network. To obtain remote management access using Telnet, use the following steps:
| Command | Purpose | |
|---|---|---|
Step 1 | Router> enable Router# | Enters enable mode. The # prompt indicates enable mode. |
Step 2 | Router# configure terminal | Enters global configuration mode. You can also abbreviate the command to config terminal. The Router(config)# prompt indicates that you are in global configuration mode. |
Step 3 | | Sets the enable password. See the "About Passwords" section. |
Step 4 | | Enters an enable secret password. Once set, a user must enter the enable secret password to gain access to global configuration mode. |
Step 5 | | Enters interface configuration mode on the Ethernet interface. You can use any Fast Ethernet interface 1-48 or any Gigabit Ethernet interface 49-50 on the Catalyst 2948G-L3 or any Gigabit Ethernet interface 1-8 on the Catalyst 4908G-L3 to configure the management port. |
Step 6 | | Enters the IP address and IP subnet mask for the interface specified in Step 5. |
Step 7 | | Enables the interface. |
Step 8 | | Returns to global configuration mode. |
Step 9 | | |
Step 10 | Router(config-line)# password password | Enters a password for Telnet sessions. |
Step 11 | Router(config-line)# end Router# | Returns to privileged EXEC mode. |
Step 12 | | Saves your configuration changes to NVRAM. |
|
Note Any Fast Ethernet interface 1-48 and any Gigabit Ethernet interface 49-50 on the Catalyst 2948G-L3 switch router, or any Gigabit Ethernet interface 1-8 on the Catalyst 4908G-L3 switch router, can be configured as a management port. |
Your switch router should now be operating correctly. You can now use Telnet to remotely assign and verify configurations.
You can display the configuration file when you are in privileged EXEC (enable) mode.
Router# show running-config
Router# show startup-config
If you made changes to the configuration, but did not yet write the changes to NVRAM, the results of the show running-config will differ from the results of the show startup-config command.
| Command | Purpose | |
|---|---|---|
Step 1 | | Enters global configuration mode. |
Step 2 | | Enters a system name. In this example, we set the hostname to "Router." |
Step 3 | | Returns to privileged EXEC mode. |
Step 4 | | Copies your configuration changes to NVRAM. |
The Catalyst 2948G-L3 and Catalyst 4908G-L3 switch routers use the onboard boot flash memory as the file storage system. The boot flash memory SIMM stores a copy of the switch router's software image. This section describes how to use the boot flash memory SIMM to perform the following system administration tasks:
You can perform the following tasks with the associated commands to view the contents of the onboard boot flash memory SIMM:
Router#pwd bootflash:
Router#dir Directory of bootflash:/ 1 -rw- 3153784 <no date> cat2948g-in-mz.old 2 -rw- 3153932 <no date> cat2948g-in-mz 16777216 bytes total (7315372 bytes free)Router#
 |
Caution When deleting files from memory, be careful not to delete all the system images. You should always retain one known good image as a backup image. |
To delete a file, use the delete command. The following example demonstrates how a specified image file is deleted using the delete command.
Router#dir Directory of bootflash:/ 1 -rw- 3153784 <no date> cat2948g-in-mz.old 2 -rw- 3153932 <no date> cat2948g-in-mz 16777216 bytes total (7315372 bytes free)Router#delete cat2948g-in-mz.old Delete filename [cat2948g-in-mz.old]? Delete bootflash:cat2948g-in-mz.old? [confirm]Router#dir Directory of bootflash:/ 2 -rw- 3153932 <no date> cat2948g-in-mz 16777216 bytes total (7315372 bytes free)
 |
Tips Before you copy software between the network server and boot flash memory in the switch router, do the following: - Make sure you have access to the network server, and obtain its IP address and name. - Verify that the server has sufficient room to accommodate the Cisco IOS software image. - Check the filename requirements and file space of the network server. |
To create a backup of the system software on a TFTP server, use the following steps beginning in privileged EXEC mode:
| Command | Purpose | |
|---|---|---|
Step 1 | | Displays the contents of boot flash memory, including the names of the images that currently reside there. Note the name of the image file you want to copy. |
Step 2 | Router# copy bootflash: tftp: |
The following example demonstrates copying a specified system image file from the boot flash memory to the default TFTP server:
Router# dir bootflash: Directory of bootflash:/ 1 -rw- 3173128 <no date> cat2948g-in-mz.120-7.W5.14.45 2 -rw- 3173364 <no date> cat2948g-in-mz.120-7.W5.14.46 16777216 bytes total (10430596 bytes free) Router# copy bootflash: tftp: Source filename []? cat2948g-in-mz.120-7.W5.14.46 Address or name of remote host []? 171.10.0.111 Destination filename [cat2948g-in-mz.120-7.W5.14.46]? yes !!.!.!!!!!!!!!.!!!!!!!!!.!.!!!!!!!!!.!.!!.!.!!!!!!!!!.!.!.!!!!!!!!!.!!!!!!!!!.!! !!!!!!!!.!.!!!!!!!!!.!!!!!!!!!!.!!!!!!!!!.!!!!!!!!!.!!!!!!!!!.!.!.!!!!!!!!!.!!.! !!!!!!!!.!.!.!.!!!!!!!!!.!.!!.!.!!!!!!!!!.!!!!!!!!!.!.!!!!!!!!!!.!!!!!!!!!.!.!.! !!!!!!!!.!!!!!!!!!.!!!!!!!!!.!!.!.!!!!!!!!!.!!.!.!.!!!!!!!!!!.!!!!!!!!!.!.!!.!!! !!!!!!.!.!.!.!.!!!!!!!!!.!!.!.!.!!!!!!!!!.!!!!!!!!!!.!!!!!!!!!.!.!!.!!!!!!!!!.!! !!!!!!!!.!.!.!.!!!!!!!!!.!!!!!!!!!.!.!!.!.!!!!!!!!!.!!.!.!.!.!!!!!!!!!!.!!!!!!!! !.!.!!.!!!!!!!!!.!.!!!!!!!!!!.!!!!!!!!!.!!.!!!!!!!!!.!.!.!!!!!!!!!.!.!.!!!!!!!!! !!!!!!!!.!!!!!!!!!.!.!.!!!!!!!!!.!!.!.!!!!!!!!!.!!.!.!.!!!!!!!!!.!!.!.!.!.!.!!!! !!! 3173364 bytes copied in 743.840 secs (4271 bytes/sec)
You can copy system image files from a TFTP server to the boot flash memory SIMM for use in booting the switch router.
It is a good idea to have a copy of the current system image on the boot flash memory SIMM in case the new image file that you copy from the TFTP server is corrupted.
|
Note You can also create a backup copy of your system image by copying the system image from boot flash memory to a Trivial File Transfer Protocol (TFTP) server. You can maintain a known good image as a backup image on the TFTP server. In case the new image file you copy from the TFTP server is corrupted, you can then retrieve the known good backup copy of the system image file from the TFTP server. |
Use the following commands to copy the system image from the TFTP server to a boot flash memory SIMM beginning in privileged EXEC mode:
| Command | Purpose | |
|---|---|---|
Step 1 | | Displays the contents of boot flash memory, including the names of the images that currently reside there. |
Step 2 | | Copies a file from a TFTP server to boot flash memory. |
The following example demonstrates copying a system image from the TFTP server to the boot flash memory SIMM without erasing the previous image file.
Router# dir bootflash: Directory of bootflash:/ 1 -rw- 3173128 <no date> cat2948g-in-mz.120-7.W5.14.45 16777216 bytes total (13604024 bytes free) Router# copy tftp: bootflash: Address or name of remote host [172.10.00.00]?

|
Note To retain existing images on boot flash, enter no when you are prompted to confirm erasing boot flash. |
In the event that the boot flash memory is full, you must erase all the files in the boot flash memory file system before copying a new image file from the TFTP server.
|
Note When boot flash memory is full, it is important to first make a copy of a known good image file, and then copy a new system image file. In case the new image file you copy from the TFTP server is corrupted, you can revert to the copy of the known good system image file. For a detailed example on how to first make a copy of a known good image file, and then copy a new system image file, refer to the "Copying the System Image to the Switch Router" section. |
Use the following commands to first erase and clean boot flash memory and then copy the new system image from the TFTP server to boot flash memory beginning in privileged EXEC mode:
| Command | Purpose | |
|---|---|---|
Step 1 | | Displays the contents of boot flash memory, including the names of the images that currently reside there. |
Step 2 | | Erases boot flash memory and copies a file from a TFTP server to boot flash memory. |
The following example demonstrates how to first erase and clean boot flash memory and then copy the new system image from the TFTP server to the boot flash memory SIMM.

Note To erase a full boot flash, enter yes when you are prompted to confirm erasing boot flash. |
If you do not have access to a network server and need to download a system image, you can copy an image from a local or remote computer (such as a PC, UNIX workstation, or Macintosh computer) using the Xmodem or Ymodem protocols. This functionality primarily serves as a disaster recovery technique. See Figure 3-1.
Xmodem and Ymodem are common protocols used for transferring files and are included in applications such as Windows 3.1 (TERMINAL.EXE), Windows 95 (HyperTerminal), Windows NT 3.5x (TERMINAL.EXE), Windows NT 4.0 (HyperTerminal), and Linux UNIX freeware (minicom).
Xmodem and Ymodem downloads are slow, so you should use them only when you do not have access to a network server. You can speed up the transfer by setting the transfer port speed to 57600 bps.
If all local system images are damaged or erased on your switch router, you can perform the file transfer by using the ROM monitor. On the Catalyst 2948G-L3 and the Catalyst 4908G-L3, you can only perform the file transfer from the ROM monitor over the console port.
|
Note Perform file transfer from the ROM monitor with either Cisco IOS Release 12.0(7)W5(15a) or later. To verify the ROM monitor version, use either the show version command from Cisco IOS software or issue the reset command from ROM MON mode. |
Figure 3-1 shows file transfer using the Xmodem or Ymodem protocols. The connection is from either a local or a remote computer to your switch router. You can make the connection using either the COM port on the local computer or using a modem with the remote computer.
To copy a Cisco IOS image from a computer or workstation to a router using the Xmodem or Ymodem protocol, use the following commands:
Command | Purpose |
|---|---|
|
|
The computer from which you transfer the Cisco IOS image must be running terminal emulation software and the Xmodem or Ymodem protocol.
This example shows a file transfer using the ROM monitor and the Xmodem protocol. To transmit with the Ymodem protocol, use the xmodem -y command.
The Catalyst 2949G-L3 and the Catalyst 4908G-L3 switch routers must have enough DRAM to hold the IOS image file being transferred. The transferred IOS image runs only in DRAM and cannot be stored in boot flash memory. Once your switch router boots up with the transferred image, you can copy a good IOS image from a TFTP server onto the boot flash file system.
|
Caution A modem connection from the telephone network to your console port introduces security issues that you should consider before enabling the connection. For example, remote users can dial into your modem and access the router's configuration settings. |
To download an IOS image from ROM monitor (using the Xmodem and Ymodem protocols), use the following steps:
Step 2 Transfer either from a remote or a local computer.
|
Note We recommend that you use the maximum speed of 57600 bps.The size of an IOS image is approximately 3MB and takes about 10 minutes to transfer at 57600 bps. |
|
Note If you are transferring from a local computer, you may need to configure the terminal emulation program to ignore RTS/DTR signals. |
You see a ROM monitor prompt in the terminal emulation window:
rommon >
Step 3 Enter the xmodem ROM monitor command. The image is downloaded to DRAM and normally executes on completion of the file transfer. The -c option specifies CRC-16 checksum, which is more thorough than a standard checksum, if supported by your computer.
The following example shows how to use the xmodem command to transfer an IOS image in ROM monitor:
rommon > xmodem -y -s57600
Do not start sending the image yet...
Invoke this application for disaster recovery.
Do you wish to continue? y/n [n]: yes
Note, if the console port is attached to a modem, both the
console port and the modem must be operating at the same baud
rate. Use console speed 57600 bps for download [confirm]
Download will be performed at 57600. Make sure your terminal
emulator is set to this speed before sending file.
Ready to receive file ...
Step 4 Start an Xmodem send operation, which is initiated from the terminal emulation software on the local or remote computer that is sending the system image to the router. Refer to your emulation software application's manual for instructions on how to execute an Xmodem file transfer.
Step 5 Reset the speed on the terminal emulator back to 9600 bps once you complete the transfer of the IOS image into DRAM.
You see the following output upon completion of the IOS image transfer:
Returning console speed to 9600. Please reset your terminal emulator to this speed... and hit 'y' to continue
|
Note The remote connection breaks when you reset the speed on the terminal emulator. |
Step 6 Disconnect the modem from the console port and reconnect the terminal line. Enter yes to continue. Your switch router automatically reboots with the IOS image.
Step 7 Download an image from CCO onto the boot flash file system after your switch router reboots.
This section provides minimal instructions for updating the system image on your Layer 3 switch router. This procedure assumes that you are manually booting the switch router from a system image on the boot flash memory SIMM. You can also configure the switch router to boot automatically from a system image specified in the BOOT environment variable. For additional information on booting options and maintaining system images, refer to the Cisco IOS Configuration Fundamentals Configuration Guide.
To update the system software, use the following steps:
Step 2 Copy the system image to the switch router.
Step 3 Reload the switch router with the new image.
Cisco IOS system images, along with other software, are available from the Software Center on Cisco Connection Online (CCO) at http://www.cisco.com. You can download system images from CCO using your browser's FTP capability, using conventional FTP, or using CCO's asynchronous dial-up interface.
For instructions on accessing and downloading software from CCO, refer to the Software Downloading from CCO via World Wide Web publication at the Software Center on CCO.
You can copy the system image to the switch router using TFTP, FTP, or RCP. If the system you used to download the image from CCO does not function as a TFTP, FTP, or RCP server, you must first copy the file to an intermediate server that provides those services to your switch router.
|
Note Before copying the system image from the server to the switch router, check the size of the file to make sure you will have enough room for it in your switch router's boot flash memory. On UNIX file systems, use the ls -la command from the directory where the file is stored to display the file size. |
In the event that the boot flash memory is full, you must erase all the files in the boot flash memory file system before copying a new image file from the TFTP server. In addition, before you copy a new image from the TFTP server, you must first download a copy of your known good image. In case the new image file you copy from the TFTP server is corrupted, you can revert to the known good image.
To copy both the known good system image and the new system image from a TFTP server to the file system on your switch router, initiate a Telnet session or console connection to the switch router. Perform the following steps in privileged EXEC mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# dir bootflash: | Displays the contents and available space in boot flash memory. If there is not enough free space to copy the new system image, perform steps 2 through 5. Otherwise, proceed to Step 4. |
Step 2 | Router# copy tftp: bootflash: | Erases boot flash memory and copies a file from a TFTP server to boot flash memory. Make sure you copy the known good system image file. |
Step 3 | Router# dir bootflash: | Displays the contents of boot flash memory. This step confirms that space was available in boot flash memory and the known good image file was copied as expected. You can now proceed with downloading the latest image. |
Router# copy tftp: bootflash: | Initiates a TFTP session to copy the new system image from the TFTP server. | |
Step 5 | Router# dir bootflash: | Displays the contents of boot flash memory. This step confirms that the latest image file was copied as expected. |
The following example shows how to erase a full boot flash memory file system, copy a known good image, and copy the latest image using TFTP:
Router# dir bootflash: Directory of bootflash:/ 1 -rw- 3168032 <no date> pci-fix 2 -rw- 1858797 <no date> domino-diag.f1 3 -rw- 3166692 <no date> cat2948g-in-mz.120-7.WX5.14.27 4 -rw- 3172268 <no date> cat2948g-in-mz.120-7.W5.14.42 5 -rw- 3173128 <no date> cat2948g-in-mz.120-7.W5.14.45 16777216 bytes total (2237976 bytes free) Router# copy tftp bootflash: Address or name of remote host []? 172.10.00.00 Source filename []? domino/cat2948g-in-mz.120-7.W5.14.45 Destination filename [cat2948g-in-mz.120-7.W5.14.45]? %Warning:There is a file already existing with this name Do you want to over write?

|
Note Make sure that the file size of the image file you copied to boot flash memory matches the image file size on the server. |
When the configuration register is set for manual booting, issuing the reload command causes the system to enter ROM monitor mode, where you enter the boot command and the name of the system image to use. To perform this procedure, you must be connected to the console port, which provides access to the switch router when in ROM monitor mode. For automatic booting, you can issue the reload command from an Ethernet connection to the route processor.
|
Note This procedure assumes that you need to change the boot field in the configuration register from its default value so that the system reverts to ROM monitor mode when you issue the reload command. |
To reload the switch router with the new system image in boot flash memory, perform the following steps, beginning in global configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Router(config)# config-register 0x0 | Sets the configuration register for manual booting from ROM monitor mode.1 |
Step 2 | Router(config)# end Router# | Returns to privileged EXEC mode. |
Step 3 | Router# | Saves your configuration changes to NVRAM. |
Step 4 | Router# reload rommon 1> | Initiates a reload of the system software. You then enter ROM monitor mode. |
Step 5 | rommon 1> dir boot flash: | Displays the contents of the file system. Perform this optional step to display and copy the name of the system image to the clipboard for use in Step 6. |
Step 6 | rommon 1> boot boot flash:filename | Reboots the switch router with the new system image. You can paste the filename from the clipboard if you copied it in Step 5. |
Step 7 | Router> show version | Displays the system software version information. Use this step to confirm that the system is loaded with the expected software version. |
| 1For details on using the configuration register to set boot parameters, refer to the Cisco IOS Configuration Fundamentals Configuration Guide. |
The following example shows setting the configuration register, saving the configuration, and reloading the switch router with the new image on the boot flash memory SIMM.
Router# configure terminal
Router(config)# config-register 0x0
Router(config)# end
