The tftpdnld ROMmon command recovery procedure fails due to invalid

syntax or variables

VERSIN 1

Core Issue

The tftpdnld ROM Monitor (ROMmon) recovery procedure must be done in a specific way in order

to work properly. Inputting the commands with incorrect syntax or variables causes the procedure

to fail.

Resolution

If the tftpdnld ROMmon command recovery procedure fails, verify that the following conditions are

met:

The TFTP server is running. The Cisco IOS file is in the root directory of the TFTP server. The filesize of the Cisco IOS image being uploaded is correct. If using Cisco TFTP Server 1.1, deselect the two check boxes in View > Options for logging

and file transfer progress. If possible, connect directly to the PC running the TFTP server with a crossover cable. The file being uploaded is compatible with hardware and memory requirements. If the router has two built-in Ethernet or fast Ethernet interfaces, always use the first

interface (usually 0/0). You must use the built-in interface. For example, if a Cisco 1700series router has a WIC-1ENET card installed, the tftpdnld ROMmon command does notwork with that card.

All variable commands must be upper case. The variable itself is case sensitive as in the caseof a filename, as shown in the following example:

rommon11>TFTP_FILE=c2600-i-mz.120-7.T.bin

TFTP_FILE= must be upper case and c2600-i-mz.120-7.T.bin is case sensitive. The DEFAULT_GATEWAY= address should not be the same address as the IP_ADDRESS=

variable. This causes the process to fail. Set the DEFAULT_GATEWAY= variable to the

address of the TFTP server.

The following example shows how to perform a tftpdnld ROMmon command recovery

procedure with a TFTP server at the 10.1.1.2 address, a 255.255.255.0 subnet mask, and a

filename of c2600-is-mz.120-7.T.bin.:

rommon 16 > IP_ADDRESS=10.1.1.1!--- This is the temporary IP address assigned to the router.rommon 17 > IP_SUBNET_MASK=255.255.255.0!--- Same as on the TFTP server.rommon 18 > DEFAULT_GATEWAY=10.1.1.2!--- Use the IP address of the TFTP server.

rommon 19 > TFTP_SERVER=10.1.1.2!--- TFTP server's IP address.rommon 20 > TFTP_FILE=c2600-is-mz.120-7.T.bin


4/4

!--- Exact name is case sensitive.rommon 21 > TFTP_CHECKSUM=0!--- This prevents checksum errors with earlier 2600 boot ROMs.rommon 22 > tftpdnld!--- This command must be lower case.IP_ADDRESS: 10.1.1.1
