This chapter describes the function and displays the syntax of each command used to load and copy system images, microcode images, and configuration files. For more information about defaults and usage guidelines, see the corresponding chapter of the Router Products Command Reference publication.
b
b filename [ip-address]
b flash [filename]
b mop filename [mac-address] [interface]
To boot the router manually, use the b ROM monitor command.
| filename | Name of the system image from which you want to netboot. |
| ip-address | (Optional) IP address of the TFTP server on which the system image resides. If omitted, this value defaults to the IP broadcast address of 255.255.255.255. |
| flash filename | (Optional) Boots the router from Flash memory with the optional filename of the image you want loaded. The filename is case sensitive. Without a filename, the first valid file in Flash memory is loaded. |
| mop filename | Boots the router interactively using MOP. The filename is the name of the file image to load. Note that for VMS systems, the file on the host always ends with the .SYS extension; do not include this extension as part of the file name. |
| mac-address | (Optional) Hardware address of the host from which to load the image. If omitted, a broadcast message is sent to all MOP boot servers, and the first MOP server to indicate that it has the file becomes the server from which the router load the image. |
| interface | (Optional) Interface out which the image is loaded. If omitted, a request is sent on all interfaces that have MOP enabled, and the interface that responds first is the one used to load the image.
|
[no] boot bootstrap flash [filename]
[no] boot bootstrap mop filename [mac-address] [interface]
[no] boot bootstrap [tftp] filename [ip-address]
To configure the filename that is used to boot a secondary bootstrap image, use the boot bootstrap global configuration command. Use the no form of this command to disable booting from a secondary bootstrap image.
| flash | Indicates that the router will be booted from Flash memory. |
| mop | Indicates that the router will be netbooted from a system image stored on a Digital MOP server. |
| tftp | (Optional) Indicates that the router will be netbooted from a system image stored on a TFTP server. |
| filename | (Optional with flash) Name of the system image from which you want to netboot. If you omit the filename when booting from Flash, the router uses the first system image stored in Flash memory. |
| ip-address | (Optional) IP address of the TFTP server on which the system image resides. If omitted, this value defaults to the IP broadcast address of 255.255.255.255. |

| interface | (Optional) Interface out which the router should send MOP requests to reach the MOP server. The interface options are async, dialer, ethernet, loopback, null, serial, and tunnel. If the interface argument is not specified, a request will be sent on all interfaces that have MOP enabled, and the interface out which the first response is received will be used to load the software. |

| mac-address | (Optional) MAC address of the MOP server on which the file resides. If the MAC address argument is not included, a broadcast message is sent to all MOP boot servers. The first MOP server to indicate that it has the file is the server from which the router gets the boot image. |
| interface | (Optional) Interface out which the router should send MOP requests to reach the MOP server. The interface options are async, dialer, ethernet, serial, and tunnel. If the interface argument is not specified, a request is sent on all interfaces that have MOP enabled, and the interface out which the first response is received is used to load the software. |
[no] boot network mop filename [mac-address] [interface]
[no] boot network [tftp | rcp] filename [ip-address]
To change the default name of the network configuration file from which you want to load configuration commands, use the boot network global configuration command. Use the no boot network command to restore the network configuration filename to the default.

| filename | (Optional with flash.) Name of the configuration file from which you want to netboot. It is case sensitive.If you do not specify a system image file with the boot system command, the router uses the configuration register settings to determine the default system image filename to boot from the network server. The router forms the default boot filename by starting with the word cisco and then appending the octal equivalent of the boot field number in the configuration register, followed by a hyphen, and the processor type name (cisconn-cpu). |

config-register value
To change the router configuration register settings, use the config-register global configuration command.
| value | Hexadecimal or decimal value that represents the 16-bit configuration register value you want to use the next time the router is restarted.

Use the no rcmd remote-host command to remove an entry for a remote user from the local authentication database.
| local-username | Name of the user on the local router. You can specify the router host name as the username. This name needs to be communicated to the network administrator or the user on the remote system. To be allowed to remotely execute commands on the router, the remote user must specify this value correctly. |
| ip-address | IP address of the remote host from which the local router will accept remotely executed commands. Either the IP address or the host name is required. |
| host | Name of the remote host from which the local router will accept remotely executed commands. Either the host name or the IP address is required. |

[no] rcmd remote-username username
To configure the remote username to be used when requesting a remote copy using rcp, use the rcmd remote-username global configuration command. To remove from the configuration the remote username, use the no rcmd remote-username command.
| username | Name of the remote user on the server. This name is used for rcp copy requests. All files and images to be copied are searched for or written relative to the directory of the remote user's account. |
[no] rcp-enable
To configure the router to allow remote users to copy files to and from the router, use the rcp-enable global configuration command. Use the no rcp-enable command to disable a router that is enabled for rcp.
reload
To reload the operating system, use the reload EXEC command.
rsh {ip-address | host} [/user username] remote-command
To execute a command remotely on a remote rsh host, use the rsh EXEC command.
| ip-address | IP address of the remote host on which to execute the rsh command. Either the IP address or the host name is required. |
| host | Name of the remote host on which to execute the command. Either the host name or the IP address is required. |
| /user username | (Optional) Remote username. If you do not specify a remote username, the router software uses the configured remote username, if one exists. Otherwise, the router software uses the username associated with the current TTY, if it is a valid name. If this name is invalid, the router software uses the host name as the username. |
| remote-command | Command to be executed remotely. This is a required parameter. Unlike UNIX, the router software does not default to a remote login. Instead, the router provides Telnet and connect services. |
[no] rsh-enable
To configure the router to allow remote users to execute commands on the router using rsh, use the rsh-enable global configuration command. Use the no rsh-enable command to disable a router that is enabled for rsh.

show bootflash
To verify boot Flash memory, use the show bootflash EXEC command.
show configuration
Use the show configuration EXEC command to display the contents of the nonvolatile memory, if present and valid.
The nonvolatile memory stores the configuration information in the network server in text form as configuration commands. The show configuration command shows the version number of the software used when you last executed the write memory command.
show flash [all]
Use the show flash EXEC command to verify Flash memory. The show flash command displays the type of Flash memory present, any files that might currently exist in Flash memory, and the amounts of Flash memory used and remaining.
