Appendix C Using ROM Monitor
How to Use the ROM Monitor—Typical Tasks
Step 5
TFTP_FILE=[directory-path/]filename
Example:
rommon > TFTP_FILE=archive/rel22/c2801-i-mz
Sets the name and location of the file that is downloaded to
the router.
Step 6
GE_PORT=[0 | 1 | 2]
Example:
rommon > GE_PORT=0
(Optional) Sets the input port to use one of the Gigabit
Ethernet ports. The default is 0.
Step 7
GE_SPEED_MODE=[0 | 1 | 2 | 3 | 4 | 5]
Example:
rommon > GE_SPEED_MODE=3
(Optional) Sets the Gigabit Ethernet port speed mode, with
these options:
• 0—10 Mbps, half-duplex
• 1—10 Mbps, full-duplex
• 2—100 Mbps, half-duplex
• 3—100 Mbps, full-duplex
• 4—1 Gbps, full-duplex
• 5—Automatic selection (default)
Step 8
TFTP_MEDIA_TYPE=[0 | 1]
Example:
rommon > MEDIA_TYPE=1
(Optional) Sets the Gigabit Ethernet connection media type,
RJ-45 (0) or SFP (1). Small form-factor pluggable (SFP)
mode is applicable only if GE_PORT=0 (gig 0/0); RJ-45
mode is available on both gig 0/0 and gig 0/1 (GE_PORT =
0 or 1). The default is 0.
Step 9
TFTP_CHECKSUM=[0 | 1]
Example:
rommon > TFTP_CHECKSUM=0
(Optional) Determines whether the router performs a
checksum test on the downloaded image.
• 1—Checksum test is performed (default).
• 0—No checksum test is performed.
Step 10
TFTP_DESTINATION=[flash0: | flash1: |
usbflash0: | usbflash1:]
Example:
rommon > TFTP_DESTINATION=usbflash0:
(Optional) Designates the targeted flash device as compact
flash or USB flash.
• flash0:—Compact flash device in port 0(default)
• flash1:—Compact flash device in port 1
• usbflash0:—USB flash device inserted in port 0
• usbflash1:—USB flash device inserted in port 1
Step 11
TFTP_MACADDR=MAC_address
Example:
rommon > TFTP_MACADDR=000e.8335.f360
(Optional) Sets the Media Access Controller (MAC)
address for this router.
Step 12
TFTP_RETRY_COUNT=retry_times
Example:
rommon > TFTP_RETRY_COUNT=10
(Optional) Sets the number of times that the router attempts
Address Resolution Protocol (ARP) and TFTP download.
The default is 18.
