Cisco Switching/Routing :: How To Delete A File In Flash On C2600
Sep 1, 2012
I want to delete the first file c2600-i-mz.122-5d in the flash. Not only delete but also reclaim the memory held by deleted file.I followed a link and i ended up with the c2600-i-mz.122-5d marked as deleted in the flash but the memory was not reclaimed.When I restarted the router, it went to ROMMON mode. This is my understanding when router tried to boot from the flash, It tried to load the first file in the flash. Since the file was marked as deleted therefore Router went to ROMMON mode.Now my question is how could I delete the first file and reclaim the memory on 2600 router?

I'm having an issue with a Cisco 2811 ISR Router. Sh ver command output lists the correct ios that the router used for booting and it says that the ios is stored in flash but when i give "sh flash" command it doesn't display the ios file. Maybe the flash is corrupted or damaged in some way? In the attached file is the output from the "sh ver" and "sh flash" commands.

I want upgrade my switches 2960-24PC-L RAM: 128MB and Flash: 28MB, but in the web page of cisco I see that the requirement of hardware is RAM: 128MB and Flash: 32MB.
I download the IOS file and this file is only 11.2MB so my question is if I can upgrade the IOS because my flash is enough for upload the IOS file.

Trying to copy the system image file from the sup-bootflash to a new 64MB ATA flash card. Yes the software can support the 64MB card.
The ATA flash card was formated successfully, however I cannot copy the system image to it so that it can boot after a power loss.
The command I tried was: console(enabled) copy sup-bootflash: slot0:
The source filename was typed in as shown in the Show Verison command.The result was: Error opening slot0: no such device.I suspect that I am missing something obvious as I am new to Cisco Switches.

Working on a C4948-10g switch. Trying to reset switch to factory settings. I have ran the Switch#>wr erase, command but the vlan's are still in the config. If you do a show vlan it still shows all the vlan text. I have tried the Switch#>delete vlan.dat, doesn't work. Tried Switch#>delete nvram:vlan.dat, doesn't work. Tried Switch#>erase startup-config, doesn't work. How can I get rid of the vlan's?

I have copied the config and vlan.dat files via tftp to the computer and want to import them to a replacement switch. Both switches are 2960 model. I get the config over fine but not sure how to get the vlan.dat file to the flash.

i have a few 3550's at the moment and when i use the delete /force /recursive flash:html command it just throws back "permission denied" this seems pretty common on the 3550 but i have never had an issue on the 2950, 3550, 2960, 3560 just the 3550.
Can any give me the command for recursive deleting on the 3550 in the console i.e. hyper terminal?

I want upgrade IOS on my 7206VXR from 12.4(12c) to 15.1(4)M5 , but the CF card only 64M.
-NAME: "disk2", DESCR: "64MB Compact Flash Disk for NPE-G1"
-Router#show bootvar
BOOT variable = disk2:c7200-jk9s-mz.124-12c.bin,15.1(4)M5 is almost 40M. So there is not enough space.I want to ask is it ok if I upgrade with normal precedure , With the command " copy tftp: disk2: " ?Does the router will automatically delete the older IOS first and then copy into the new one ? Or Is there something I should pay attention first ?

I have this 2801 in a critical environment. We had a brief power blip, and even though the router is on UPS, something happened. Anyway, after working with TAC, they determined the flash card had gone corrupt. Lucky for me I had a spare 2801 in my office, I grabbed that flash card and plugged it in and we're back up and going.
TAC sent me a new flash card. No matter what I do, I cannot get IOS to load on this thing! I am stuck in rommon. Here's what I've tried:
tftpdnld in rommon, times out. using another 2801 as a tftp-server. doesn't complete. using xmodem. ugh. never seems to get started. booting the router with a known good flash card, so I can get to ena, and "copy tftp flash".
have used tftpd32, Solar Winds TFTP server, What's Up Gold TFTP server, and open source tftp from sourceforge. With the tftp32, it always gets to exactly 73% download and then times out (it says, I have a feeling it's noty really a timeout). I have tried having the router and tftp server the only devices on a switch, i have tried the router plugged directly into the tftp server with a cross connect cable. No happiness. The open source tftp server reported (and I have to paraphrase, I am not near the router) "client does not support block number recount" or something like that. The client being the 2801.
The iOS file is about 45M. Someone asked me if the flash card was formatted...would that matter? would the tftp even start if it wasn't?
OK, I've gone on long enough. TAC is dispatching a new card AND 2801!

I had an issue today on a 4507r today where when I formatted the compact flash in slot0: (512mb) it caused the CPU to spike to 100% this took about 1.5 hours and did not cause adjacency loss or any thing, but was worrisome. This was a sup IV is this normal and should u let it complete like I did? Also when I copied the os to it from boot flash it caused the same behavior. I have done this a bunch in 6500 sup 720 without this issue?

I am trying to research the possiblity of backing up IOS and configurations from an Etherswitch module, and being able to store the files onto the Host Router's flash (3925 ISR). and then being able to recover that IOS and configuration, in case I have to replace the Etherswitch Module.

Every time I delete the directory flash and reinstall it, I get an error:
Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin"
Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin" Interrupt within 5 seconds to abort boot process.
That is the message I get. It's set to NO manual boot, but it keeps making me manually boot it. I am at a loss, I've done 3 switches and they all keep doing the same thing.

I recently tried to manually format the flash on a model WS-2960S-48TS-L switch running IOS version 15.0(2)SE. While executing the operation I got the following error - mifs[8]: Failed to create superblock %Error formatting flash (I/O error).As a result the flash is no longer accessible by the switch. I spoke with Cisco and they indicated that a switch reload would remount the flash and make it accessable again but the .bin file would need to be reloaded using the xModem recovery procedure (what a pain).The next IOS version 15.0(2)SE1 will supposedly fix this bug but it has not been released yet. In the meantime if you are running 15.0(2)SE you may want to hold off performing a "format flash:" function on a 2960S.

Got a problem with my 1760 router. Bought it from ebay and booted it on today and got this error,It has 180224K/16384K bytes of memory and 2 paritions of 32768K flash.I erased both partitions and put a different version of the IOS on (still 12.4) and there is no difference, still get the errors.These aren't on any of my other 1760 routers so I assume they are linked to the problem.

Cisco... Have two new 3750X switches (24P-L, and 48PF) trying to stack. Brought them up together a few weeks ago with the 24P using LANBase and the 48 IPBase. The expected happened. They saw each other in the stack ring, and the 24 port was excluded due to license miss match. This was corrected. Now both are IPBase.Now I have the two switches stacked, and boot the 48 and 24 at the same time. Monitoring the 48 I get a check message "FIPS: Flash key check: End, Not found. FIPS: Stacking Not Found". The 48 does confirm the stack cable is connected. This happens early in the boot process, before master election.OK.... Now looking at the 24 Port. After applying the new license, and actually booting successfully and few times. It will no longer load the boot file. Wants an environment variable. Going to have to dig into ancient history for that. Had to deal with that one about 8 years ago. Do not feel that is part of the stack disable issue though.

I am trying to configure a switch that was given to me. They don't know the password to anything. I have already tried to recover it. The problem is, the switch doesn't load flash, or will copy flash from xmodem either. It also doesnt load the helper or boot. It is user mode and lets me do nothing. It doesnt let me use the enable command to get into it. I would like to start the config from scratch. Its a 3500xl switch, 24 ports. I dont know what to do with it. I am trying to study for my CCENT Exam and would like a switch that worked.

I read that there are internal and external flash memory in 3725 router that can max up to 128mb. So adding the sizes of internal and external flash memory, will that total to 256mb?
And also is the internal flash of 3725 just the same with its external flash?
