相应peng的号召，所以我起了这个名字的主题。但是不知道是否经典：） 首先是文件系统方面 How to Download a Software Image to a Cisco 2600 via TFTP Using the tftpdnld ROMMON Command
This document eXPlains how to download a software image to a Cisco 2600 using Trivial File Transfer PRotocol (TFTP) over the first LAN port using the tftpdnld ROMMON command.
Notes:
* The ROMMON TFTP transfer works on the first LAN port only; however, for the Cisco 2612, you can choose the Token Ring or Ethernet port.
* You can only download files to the router. You cannot use ROMMON TFTP to get files from the router.
* Does not support source route bridging on Token Ring ports.
The variables to set for tftpdnld are shown below:
usage: tftpdnld Use this command for disaster recovery only to recover an image via TFTP. "tftpdnld" has no arguments. Monitor variables are used for arguments. (Syntax: "VARIABLE_NAME=value" and use "set" to show current variables.) "ctrl-c" or "break" stops the transfer before Flash erase begins.
The following variables are REQUIRED to be set for tftpdnld: IP_ADDRESS: The IP address for this unit IP_SUBNET_MASK: The subnet mask for this unit DEFAULT_GATEWAY: The default gateway for this unit TFTP_SERVER: The IP address of the server to fetch from TFTP_file: The filename to fetch
The following variables are OPTIONAL: TFTP_VERBOSE: Print setting. 0=quiet, 1=progress(default), 2=verbose TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=7) TFTP_TIMEOUT: Overall timeout of operation in seconds (default=2400) TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes (default=1) rommon 14 >
The variables to set for Token Ring are shown below:
TR_1E1R_PORT On the Cisco 2612, this variable sets the Token Ring or Ethernet port. 0 = use Ethernet port 1 = use Token Ring port Default is 0 TR_SPEED_MODE For a Token Ring port, this variable sets the ring speed and duplex mode. 0 = 4 Mbps half-duplex mode 1 = 4 Mbps full-duplex mode 2 = 16 Mbps half-duplex mode 3 = 16 Mbps full-duplex mode Default is 2
The variables to set for Fast Ethernet are shown below:

How to Download a Software Image to a Cisco 2600 through the Console Port Using the xmodem ROMMON Command
You can download a software image to a Cisco 2600 through the console port using the xmodem [-cyr] [filename] ROMMON command, where:
* -c specifies CRC-16
* -y specifies YMODEM protocol
* -r copies the image to RAM. (It does not copy to Flash. Leave off the -r to copy the image to Flash.)
Notes:
* The ROMMON XMODEM/YMODEM transfer works on the console port only.
* You can only download files to the router. You cannot use XMODEM/YMODEM to get files from the router.
