|
| If your Cisco router experiences difficulties and no longer contains a valid Cisco IOS software image in |
| flash memory, you can download a new Cisco IOS image using one of the following ROM monitor |
| commands: |
|
| xmodem—(All Cisco 2600 series routers) Use this command to copy a Cisco IOS image from the |
| console, if the computer attached to your console has a terminal emulator with Xmodem capability |
| Downloading a Cisco IOS image from a console is very slow |
|
| rommon 1 > xmodem -c c2600-is-mz.122-10a.bin |
|
|
| tftpdnld—(Except Cisco 2691) Use this command to copy a Cisco IOS image from a TFTP server |
| that is accessible through the FastEthernet 0/0, Ethernet 0/0, or Token Ring 0/0 port |
|
| rommon 3 > set |
| rommon 4 > IP_ADDRESS=171.68.171.0 |
| rommon 17 > IP_SUBNET_MASK=255.255.254.0 |
| rommon 18 > DEFAULT_GATEWAY=171.68.170.3 |
| rommon 19 > TFTP_SERVER=171.69.1.129 |
| rommon 20 > TFTP_FILE=c2600-is-mz.113-2.0.3.Q |
| rommon 21 > tftpdnld |
|
|
|
| Copy IOS from router to router |
| first set the one router as tftp server |
| Router(Config)#tftp-server flash:ios name |
| in the next router |
| router#copy tftp flash: |
