Recovering Cisco IOS Software imagesIf your Cisco router experiences difficulties and no longer contains avalid Cisco IOS software image in flash memory, you can download a newCisco IOS image using one of the following ROM monitor commands:
Hi all. - blank.gifxmodem—(AllCisco 2600 series routers) Use this command to copy a Cisco IOS imagefrom the console, if the computer attached to your console has aterminal emulator with Xmodem capability. See the "Copying an Image from the Console Using the xmodem Command" procedure.
Note blank.gifDownloadinga Cisco IOS image from a console is very slow. This procedure should beused only in an emergency and is not recommended for normal Cisco IOSimage upgrades.

For the fastest possible download from a console, set the console speed to 115200 bps by using the confreg ROM monitor command. See the "Configuration Register Commands" procedure.
blank.giftftpdnld—(ExceptCisco 2691) Use this command to copy a Cisco IOS image from a TFTPserver that is accessible through the FastEthernet 0/0, Ethernet 0/0,or Token Ring 0/0 port. See the "Copying an Image from a TFTP Server Using the tftpdnld Command" procedure.
note.gif Note blank.gifThetftpdnld command is not available on the Cisco 2691 router. Therecommended method for installing a Cisco IOS image on a Cisco 2691router is from a CompactFlash memory card loaded in the externalCompactFlash memory card slot. See the "Entering Boot Commands" procedure.

1841 router in rommon mode cannot install flash


Basically you will need to use TFTP to get the IOS back on. HERE is an article from Cisco that explains how to do it. I have done this before and even though it takes a while to reload the IOS (because in my case I had to use a serial connection at 9600 baud) it does work.

Auto backup IOS of router.


If you want to back up your Configuration on any Cisco Router, You can just use RANCID (http://adi-sunardy.net/2008/12/24/how-to-automating-cisco-router-switch-firewall-backups-on-fedora/). 
Or, some other solution:
  • ciscowork
  • ziptie
  • solarwind 
  • cirrusmanager
Or follow these instruction: http://www.techexams.net/forums/ccna-ccent/22447-how-setup-tftp-server-backup-restore-2500-ios.html

I have a problem with a cisco catalyst 2948G-L3. A have erase of mistake the bootflash. I have tried in some way to download a new IOS, i have the IOS bu i cannot download it in the flash because the...


Two ways to do that are xmodem (slow) or Tftp from rommon mode. (fast)
Place the IOS image in your tftp server directory and start tftp server.
Then enter the following in the switch exactly as below as all are case sensative:
rommon 1> IP_ADDRESS=xxx.xxx.xxx.xxx
rommon 2> IP_SUBNET_MASK=xxx.xxx.xxx.xxx
rommon 3> DEFAULT_GATEWAY=xxx.xxx.xxx.xxx
rommon 4> TFTP_SERVER=xxx.xxx.xxx.xxx
rommon 5> TFTP_FILE=full file name of ios as it reads
rommon 6> TFTP_CHECKSUM=0
this one is in lower case
rommon 7> tftpdnld

If you dont have a tftp server below is a link to a free one
http://www.solarwinds.net/Tools/Free_tools/TFTP_Server/

You will need the .bin IOS image for this and not the .tar file. The .tar file contains router cluster management files that you must issue the archive tar command to load all of the files. Can do that if needed after router is back online.

ICMP packets not working on Dell Latitude D620


With vista I had the same problem, but when I enabled network fileshareing and set up some network drives it started to answer on ping requests, so it should be one of the networking protocols to enable.

FAIL UPGRADE


run wireshark,  if you see it trying to access 10.0.0.1 via TFTP, IOS was wiped,  just set a tftp server on that address and it will download the dfault image.  search cisco to find out the name of the file it is looking for, or look through the wireshark packets

Upgrade firmware on a cisco ASA 5500 firewall


This is for the pixes, I haven't upgraded an asa yet...should be close or the same

* find latest version of code, these are usually *.bin files located on http://www.cisco.com/cgi-bin/tablebuild.pl/pix
* confirm the flash and RAM requirements of the PIX OS software versus what the PIX has (”sho ver”)
* make sure you have a backup of the old PIX OS and PDM to the tftp server (or at least confirm the software is there)
Note: You cannot back them up from the PIX, so you will need to download them and put them on the tftp server * put in a change control form
* once change controls confirms date/time do the upgrade:
wri mem*** only if you save your configs via tftp wri net conf t ca save all copy tftp://your tftp server ip/pix635.bin flash:imageskip this if you don't use pdm copy tftp://your tftp server ip/pdm-304.bin flash:pdm *** if this is a failover pair, upgrade the other pair reboot
