System Image and Microcode Commands
This chapter provides detailed descriptions of the commands used to load and copy system images and microcode images. System images contain the system software. Microcode images contain microcode to be downloaded to various hardware devices.
For configuration information and examples, refer to the "Loading and Maintaining System Images and Microcode" chapter in the Configuration Fundamentals Configuration Guide.
Flash Memory File System Types
Cisco platforms use one of three different Flash memory file system types. Some commands are supported on only one or two file system types. This chapter notes commands that are not supported on all file system types.
Refer to Table 22 to determine which Flash memory file system type your platform uses.
Replaced Commands
Commands in this chapter that have been replaced by new commands continue to perform their normal functions in the current release but are no longer documented. Support for these commands will cease in a future release.
Table 23 maps the old commands with their replacements.
clear card-message
To remove the user-specified message that is displayed on the LED on the front panel of one or more line cards and revert to the normal status message for the line card, use the clear card-message privileged EXEC command.

copy xmodem: flash-filesystem:
Syntax Description
Command Modes
EXEC
Command History
Usage Guidelines
Copying a file using FTP, rcp, or TFTP is much faster than copying a file using Xmodem. Use the copy xmodem: command only if you do not have access to an FTP, TFTP, or rcp server.
This copy operation is performed through the console or AUX port. The AUX port, which supports hardware flow control, is recommended.
No output is displayed on the port over which the transfer is occurring. You can use the logging buffered command to log all router messages sent to the console port during the file transfer.
Examples
The following example initiates a file transfer from a local or remote computer to the router's internal Flash memory using the Xmodem protocol:
copy xmodem: flash:Related Commands
copy ymodem:
The copy ymodem: and copy ymodem commands are identical. Refer to the description of the copy command for more information.

execute-on
To execute commands remotely on a line card, use the execute-on slot privileged EXEC command.
execute-on {slot slot-number | all} command
Syntax Description
Command Modes
Privileged EXEC
Command History
11.2 GS
This command was added to support the Cisco 12000 series Gigabit Switch Routers.
Usage Guidelines
Use this command to execute a command on one or all line cards to monitor and maintain information on one or more line cards.
You can use the execute-on privileged EXEC command only from Cisco IOS software running on the GRP card.
Note
In Cisco IOS Release 11.2(9)GS, the execute-on command does not work properly on commands that require input, the "more" autopaging mechanism does not function, and the line card help is not available.
Note
You can also use the attach privileged EXEC command, but using the execute-on slot command saves you some steps. For example, first you must use the attach command to connect you to the Cisco IOS software running on the line card, next you must issue the command, and finally you must disconnect from the line card to return to the Cisco IOS software running on the GRP card. With the execute-on slot command, you can perform three steps with one command.
In addition, the execute-on all command allows you to perform the same command on all line cards.
Examples
The following example executes the show controllers command on the line card in slot 4:
Router# execute-on slot 4 show controllers========= Line Card (Slot 4) =======Interface POS0Hardware is BFLC POSlcpos_instance struct 6033A6E0RX POS ASIC addr space 12000000TX POS ASIC addr space 12000100SUNI framer addr space 12000400SUNI rsop intr status 00CRC16 enabled, HDLC enc, int clockno loopInterface POS1Hardware is BFLC POSlcpos_instance struct 6033CEC0RX POS ASIC addr space 12000000TX POS ASIC addr space 12000100SUNI framer addr space 12000600SUNI rsop intr status 00CRC32 enabled, HDLC enc, int clockno loopInterface POS2Hardware is BFLC POSlcpos_instance struct 6033F6A0RX POS ASIC addr space 12000000TX POS ASIC addr space 12000100SUNI framer addr space 12000800SUNI rsop intr status 00CRC32 enabled, HDLC enc, int clockno loopInterface POS3Hardware is BFLC POSlcpos_instance struct 60341E80RX POS ASIC addr space 12000000TX POS ASIC addr space 12000100SUNI framer addr space 12000A00SUNI rsop intr status 00CRC32 enabled, HDLC enc, ext clockno loopRouter#Related Commands

Sets the mode of operation and thus control the type of the ATM cell used for cell-rate decoupling on the SONET PLIM.
microcode
To specify the location of the microcode that you want to download from Flash memory into the writable control store (WCS) on a Cisco 7000 series with RSP7000 or Cisco 7500 series, use the microcode global configuration command. Use the no form of this command to load the microcode bundled with the system image.
microcode interface [flash-filesystem:filename [slot] | system [slot]]
no microcode interface [flash-filesystem:filename [slot] | system [slot]]
Syntax Description
Defaults
The default is to load from the microcode bundled in the system image.
Command Modes
Global configuration
Command History
Usage Guidelines
When using HSA for simple hardware backup, ensure that the master and slave RSP card contain the same microcode image in the same location when the router is to load the interface processor microcode from a Flash file system. Thus, if the slave RSP becomes the master, it will be able to find the microcode image and download it to the interface processor.
Examples
In the following example, all FIP cards will be loaded with the microcode found in Flash memory file fip.v141-7 when the system is booted, when a card is inserted or removed, or when the microcode reload global configuration command is issued. The configuration is then written to the startup configuration file.
Router(config)# microcode fip slot0:fip.v141-7Router(config)# endRouter# copy system:running-config nvram:startup-configRelated Commands
Views the system console output generated during the Flash load helper operation.
microcode (Cisco IOS image)
To load a Cisco IOS software image on a line card from Flash memory or the GRP card on a Cisco 12000 series Gigabit Switch Router, use the microcode global configuration command. To load the microcode bundled with the GRP system image, use the no form of this command.
microcode interface {flash file-id [slot] | system [slot]}
no microcode interface [flash file-id [slot] | system [slot]]
Syntax Description
Defaults
The default is to load the image from the GRP card.
Command Modes
Global configuration
Command History
10.3
This command was introduced.
11.2 GS
This command was modified to load the Cisco IOS software image onto a line card in the Cisco 12000 series Gigabit Switch Routers.
Usage Guidelines
You must be in configuration mode to enter this command. Immediately after you enter the microcode reload command and press Return, the system reloads all microcode. Global configuration mode remains enabled. After the reloading is complete, enter the exit command to return to the EXEC system prompt.
In addition to the Cisco IOS image that resides on the GRP card, each line card on a Cisco 12000 series has a Cisco IOS image. When the router is reloaded, the specified image is loaded onto the GRP card and then automatically downloaded to all the line cards.
Normally, you want the same Cisco IOS image on the GRP card and all line cards. However, if you want to upgrade a line card with a new version of microcode for testing or to fix a defect, you might need to load a Cisco IOS image that is different from the one on the line card. Additionally, you might need to load a new image on the line card to work around a problem that is affecting only one of the line cards.
To load a Cisco IOS image on a line card, first use the copy tftp command to download the Cisco IOS image to a slot on one of the PCMCIA Flash memory cards. Then use the microcode command to download the image to the line card followed by the microcode reload command to start the image. To verify that the correct image is running on the line card, use the execute-on slot slot show version command.
For information on how to load Cisco IOS images, refer to the "Loading Images and Configuration Files" chapter in the Configuration Fundamentals Configuration Guide. For additional information, refer to the "Observing System Startup and Performing a Basic Configuration" chapter in the Cisco 12000 series installation and configuration guides.
Examples
In the following example, the Cisco IOS software image in slot 0: is downloaded to the line card in slot 10. This software image is used when the system is booted, a line card is inserted or removed, or the microcode reload global configuration command is issued.
To verify that the correct version is loaded, use the execute-on slot 10 show version command.
Router(config)# microcode oc3-POS-4 flash slot0:fip.v141-7 10Router(config)# microcode reload 10Router(config)# exitRouter#Related Commands
microcode reload
To reload the Cisco IOS image on a line card on the Cisco 7000 series with RSP7000, Cisco 7500 series, or Cisco 12000 series routers after all microcode configuration commands have been entered, use the microcode reload global configuration command.
microcode reload [slot-number]
Syntax Description
Command Modes

Command History
Usage Guidelines
In addition to the Cisco IOS image that resides on the GRP card, each line card on Cisco 12000 series routers has a Cisco IOS image. When the router is reloaded, the specified Cisco IOS image is loaded onto the GRP card and automatically downloaded to all the line cards.
Normally, you want the same Cisco IOS image on the GRP card and all line cards. However, if you want to upgrade a line card with a new version of microcode for testing or to fix a defect, you might need to load a different Cisco IOS image. Additionally, you might need to load a new image on the line card to work around a problem affecting only one of the line cards.
To load a Cisco IOS image on a line card, first use the copy tftp command to download the Cisco IOS image to a slot on one of the PCMCIA Flash memory cards. Then use the microcode command to download the image to the line card, followed by the microcode reload command to start the image. To verify that the correct image is running on the line card, use the execute-on slot slot show version command.
For information on how to load Cisco IOS images, refer to the "Loading Images and Configuration Files" chapter in the Configuration Fundamentals Configuration Guide. For additional information, refer to the "Observing System Startup and Performing a Basic Configuration" chapter in the Cisco 12000 series installation and configuration guides.

xmodem
To copy a Cisco IOS image to a Cisco 1600 series or Cisco 3600 series router using the ROM monitor and the Xmodem or Ymodem protocol, use the xmodem ROM monitor command.
xmodem [-c] [-y] [-e] [-f] [-r] [-x] [-s data-rate] [filename]
Syntax Description
Defaults
Xmodem protocol with 8-bit CRC, file downloaded into Flash memory and executed on completion.
Command Modes
ROM monitor
Command History
Usage Guidelines
The Cisco 3600 series does not support XBOOT functionality. If your Cisco IOS image is erased or damaged, you cannot load a new image over the network.
Use the xmodem ROM monitor command to download a new system image to your router from a local personal computer (such as a PC, Mac, or UNIX workstation), or a remote computer over a modem connection, to the router's console port. The computer must have a terminal emulation application that supports these protocols.
Cisco 3600 series
Your router must have enough DRAM to hold the file being transferred, even if you are copying to Flash memory. The image is copied to the first file in internal Flash memory. Any existing files in Flash memory are erased. There is no support for partitions or copying as a second file.
Cisco 1600 series
If you include the -r option, your router must have enough DRAM to hold the file being transferred. To run from Flash, an image must be positioned as the first file in Flash memory. If you are copying a new image to boot from Flash, erase all existing files first.
Caution
Note
Examples
The following example uses the xmodem -c filename ROM monitor command to copy the file new-ios-image from a remote or local computer:
rommon > xmodem -c new-ios-imageDo not start the sending program yet...File size Checksum File name1738244 bytes (0x1a8604) 0xdd25 george-admin/c3600-i-mzWARNING: All existing data in bootflash will be lost!Invoke this application only for disaster recovery.Do you wish to continue? y/n [n]: yesReady to receive file new-ios-image ...Related Commands
