Appendix C Using the ROM Monitor
• Token Ring platform—Only accepts and sends Token Ring frames with IEEE802.3 SNAP frames.
Does not support any frames with routing information fields (RIFs), limiting all use of the tftpdnld
command to a TFTP server on the local ring. If the TFTP server resides off the local ring, you must
establish a path to the server through a router or transparent bridge from the local ring.
tftpdnld [-h] [-r]—Begins the TFTP copy procedure.
Options include the following:
h—Displays the tftpdnld command help screen.
•
r—Loads the Cisco IOS software image only to DRAM and launches the image without writing the
•
image into Flash memory.
The tftpdnld command requires that you specify certain variables when you issue the command. The
syntax for specifying the variables is:
VARIABLE_NAME=value
The variables that you must specify include the following:
IP_ADDRESS—IP address for the router you are using.
•
• IP_SUBNET_MASK—Subnet mask for the router you are using.
DEFAULT_GATEWAY—Default gateway for the router you are using.
•
• TFTP_SERVER—IP address of the server from which you want to download the image file.
TFTP_FILE—Name of the file that you want to download.
•
The following tftpdnld command variables are optional:
TFTP_VERBOSE—Print setting. The default is 1.
•
–
–
–
TFTP_RETRY_COUNT—Number of times from 1 to 65535 that the ROM monitor will retry ARP
•
and ACK. The default is 7 retries.
TFTP_TIMEOUT—Overall timeout of the download operation in seconds. The range is from
•
1 to 65535 seconds. The default is 7200 seconds.
• TFTP_CHECKSUM—Performs a checksum test on the image. 0=checksum off, 1=checksum on.
The default is 1.
FE_SPEED_MODE—Sets the Fast Ethernet speed and duplex mode. 0=10 Mbps half-duplex mode,
•
1=10 Mbps full-duplex mode, 2=100 Mbps half-duplex mode, 3=100 Mbps full-duplex mode,
4=auto-negotiation. The default is 4.
Note
OL-2171-02
0=quiet—After you enter the tftpdnld command, the prompt
Do you wish to continue? y/n:
is the only information that displays until the command completes successfully or fails.
1=progress—Displays the state of the required tftpdnld command variables. Also displays
progress characters to indicate successful and lost packet transmissions.
2=verbose—Displays all progress print setting messages, along with error information. The
information provided by this print setting may be useful when debugging interface link and
configuration problems that may prevent connecting to the TFTP server.
Specify the FE_SPEED_MODE variable only for routers with a Fast Ethernet network
interface.
