How to Upgrade the System Image

Step 5
Set the TFTP server IP address, which is the location from which the software will be downloaded:
rommon > TFTP_SERVER=172.16.23.33
Step 6 Set the name and directory location to which the image file will be downloaded onto the router. For
example:
rommon > TFTP_FILE=archive/rel22/c2600-i-mz
Step 7
(Optional) Set the input port to use a Gigabit Ethernet port, available on Cisco 2800 series and
Cisco 3800 series routers. Usage is GE_PORT=[0 | 1], selecting either gig 0/0 or gig 0/1. For example:
rommon > GE_PORT=0
Step 8 (Optional) Set the Ethernet connection media type, RJ-45 or SFP. Usage is MEDIA_TYPE=[0 | 1],
where RJ-45=0 and SFP=1 (SFP is applicable only if GE_PORT=0 in the previous step):
rommon > MEDIA_TYPE=1
Step 9
(Optional) Decide whether the router will perform a checksum test on the downloaded image. Usage is
TFTP_CHECKSUM=[0|1], where 1=checksum test is performed (default) and 0=no checksum test. For
example:
rommon > TFTP_CHECKSUM=0
Step 10 (Optional) Set the number of times that the router will attempt Address Resolution Protocol (ARP) and
TFTP download. The default is 7 attempts. For example:
rommon > TFTP_RETRY_COUNT=10
Step 11
(Optional) Set the amount of time, in seconds, before the download process times out. The default is
2400 seconds (40 minutes). The following example shows 1800 seconds (30 minutes):
TFTP_TIMEOUT=1800
Step 12 (Optional) Configure how the router will display the file download progress. Usage is
TFTP_VERBOSE=[0 | 1 | 2], where:
0=No progress is displayed.
1=Exclamation points (!!!) are displayed to indicate file download progress. This is the default setting.
2=Detailed progress is displayed during the file download process, for example:
Initializing interface.
Interface link state up.
ARPing for 1.4.0.1
ARP reply for 1.4.0.1 received.
MAC address 00:00:0c:07:ac:01
Step 13 Use the set command to display the ROM monitor environment variables to verify that you have
configured them correctly. For example:
rommon > set
Step 14
Download the system image, as specified by the ROM monitor environmental variables, using the
tftpdnld [-r] command. Without the -r option, the command downloads the specified image and saves
it in flash memory, deleting all existing data in all partitions in flash memory. Using the -r option
downloads and boots the new software but does not save the software to flash memory.
rommon> tftpdnld [-r]
