How to Use the ROM Monitor—Typical Tasks
Step 8
GE_PORT=
[
0
|
1
]
Example:
rommon > GE_PORT=0
(Optional) Sets the input port to use one of the Gigabit
Ethernet ports (not available on Cisco 1800 series routers,
Cisco 2801 routers, or Cisco 2811 routers).
Step 9
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)
(This option is not available on Cisco 1800 series routers,
Cisco 2801 routers, or Cisco 2811 routers.)
Step 10
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). (This option is not available on Cisco 1800 series
routers, Cisco 2801 routers, or Cisco 2811 routers.)
Step 11
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 12
TFTP_DESTINATION=[flash: | usbflash0: |
usbflash1:]
Example:
rommon > TFTP_DESTINATION=usbflash0:
(Optional) Designates the targeted flash device as compact
flash or USB flash.
•
flash:
—Compact flash device (default).
•
usbflash0:
—USB flash device inserted in port 0
•
usbflash1:
—USB flash device inserted in port 1
Step 13
TFTP_MACADDR=
MAC_address
Example:
rommon > TFTP_MACADDR=000e.8335.f360
(Optional) Sets the Media Access Controller (MAC)
address for this router.
Step 14
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 7.
Step 15
TFTP_TIMEOUT=
time
Example:
TFTP_TIMEOUT=1800
(Optional) Sets the amount of time, in seconds, before the
download process times out. The default is 2400 seconds
(40 minutes).
