How to Upgrade the System Image
Set the TFTP server IP address, which is the location from which the software will be downloaded:
Step 5
rommon > TFTP_SERVER=172.16.23.33
Set the name and directory location to which the image file will be downloaded onto the router. For
Step 6
example:
rommon > TFTP_FILE=archive/rel22/c2600-i-mz
(Optional) Set the input port to use a Gigabit Ethernet port, available on Cisco 2800 series and
Step 7
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
(Optional) Set the number of times that the router will attempt Address Resolution Protocol (ARP) and
Step 10
TFTP download. The default is 7 attempts. For example:
rommon > TFTP_RETRY_COUNT=10
(Optional) Set the amount of time, in seconds, before the download process times out. The default is
Step 11
2400 seconds (40 minutes). The following example shows 1800 seconds (30 minutes):
TFTP_TIMEOUT=1800
(Optional) Configure how the router will display the file download progress. Usage is
Step 12
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
Use the set command to display the ROM monitor environment variables to verify that you have
Step 13
configured them correctly. For example:
rommon > set
Download the system image, as specified by the ROM monitor environmental variables, using the
Step 14
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]
