Downloading Images
Two procedures are provided for copying ROMMON images to the supported Cisco routers: one
performed in ROMMON mode using the tftpdnld command, and another performed in IOS EXEC
mode, using the copy tftp command. You may use either procedure. The examples below use the
12.2(4r)XM2 ROMMON upgrade image, and can be used in all Cisco 800 series routers that support
ROMMON upgrade images. As it was originally only required for Cisco 827-4V routers, it has a name
specific to the Cisco 820 series of routers with the version number appended:
C820_RM_ALT.srec.122-4r.XM2. Later versions of ROMMON upgrade files will be named following
a similar pattern.
Upgrading the ROMMON Image from ROMMON Mode
Complete these steps to upgrade the ROMMON image from ROMMON mode.
Step 1 Download the ROMMON image C820_RM_ALT.srec.122-4r.XM2 from CCO, and place it on your
TFTP server.
Step 2 Place the router in ROMMON mode by sending a telnet break command during the router reboot
sequence. The following prompt will be displayed, indicating entry into ROMMON mode:
rommon>
Step 3 In ROMMON mode, set the following parameters by typing the names followed by an equals sign as
shown, and then typing a value for the parameter.
IP_ADDRESS=
IP_SUBNET_MASK=
DEFAULT_GATEWAY=
TFTP_SERVER=
TFTP_FILE=
Table 1 describes the type of value to provide for each parameter.
Step 4 Verify the parameter settings by entering the set command. Correct any mistakes by reentering the
parameter and value.
rommon>set
TFTP_CHECKSUM=0
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=1.6.0.1
