ROM Monitor Syntax Conventions

The ROM monitor syntax in this appendix uses the following conventions:

•Square brackets [ ] denote an optional element. In the following example, the element abc is not required, but you can specify it if you choose:

command [abc]

•If a minus option is followed by a colon (for example, [-s:]) you must provide an argument for the option.

•A term in italics means that you must fill in the appropriate information. In the following example, you replace the term in italics with the interface type you are using:

command type interface

Command Descriptions

This section lists some useful ROM monitor commands. Refer to the Cisco IOS configuration guides and command references for more information on ROM monitor commands.

boot or b—Boot an image.

–Boots the first image in flash memory.

–flash:/slot0 [name] boots the Cisco IOS software from flash memory.

Note The above command is not available on the Cisco VG224.

–filename tftpserver boots from the specified file over the network from the specified TFTP server. For example:

boot cvg224-i-mz 172.15.19.11

–filename boots from the boothelper image because it does not recognize the device ID. This form of the command is used to netboot the image named filename.

•The Cisco VG224 does not have a dedicated boothelper image ([rx]boot) as used by some other Cisco routers. With the Cisco VG224, the first image in flash memory is invoked as the default boothelper image anytime the ROM monitor does not recognize the device ID in the boot command.
