I have a 512MB USB Flash device and was able to boot the IOS on the C2960 from it.After that i tried to Copy the IOS file from the USB to the system flash, but it could not find the USB Device.At plugging in the device the systems tells me: "Transfer type 2 not supported" I configured the USB device in NTFS and FAT both are able to boot with the ROMMON, but the normal system does not accept them and i know i can do the copy over a TFTP from my laptop, but it is strange that rommon accepts the usb device and the system does not?

When I use ASDM or the CLI to copy (ftp) files from my management station to flash on my ASA5520. I get to 99% and then the gui or cli window hangs.
The ASA itself completely freezes i.e. no traffic in or out until I kill the transfer window and then it may reboot
[and yes, there is more than enough free space on the flash file system for the files]
ASA5520 V8.2(3) / ASDM V6.4(5)

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.

I have a WS- C2924C-XL switch that I would like to upgrade the IOS version on. The IOS version in question can only be installled on an 8MB version of this switch, I have tried to confirm the amount of memory present in the device but I am getting conflicting values depending on where I look.The model number would indicate that this device is a 4MB version, therefore not compatable with the upgrade.Running the show version command from the CLI shows Processor having 8192K/1024K bytes of memory.Accessing the switch via the VMS management interface displays a value of 4MB.

i have to configure 80 Cisco 876 routers, so i planned to copy config via tftp from one configured router to PC, edit it in text editor (change ip addresses, dhcp pools, vpn keys...) and then copy it via tftp to another router, etc... Configuration looks fine and it works when i paste it in cli, but when i copy it via tftp i'm getting strange problems like dhcp not working or snmp not accessible. Am I missing something.
Here's config from router with dhcp problem:
ROUTER#sh run
version 15.1
no service pad
service tcp-keepalives-in
service tcp-keepalives-out
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
service password-encryption
service sequence-numbers(code)

I was upgrading IOS on 4507 R with dual supervisor.I download the IOS on Active supervisior and did reboot.After reboot i login to switch then i got switch standby prompt.I found that after reboot active supervisior became standby supervisior.
Now new IOS is on standby supervisior.Need to confirm below..So this means that IOS does not syn within the supervisiors as compared to config right ?
-Which command i can use that will copy IOS from standby supe to Active supe??
-Which command i can use that will show both active and standby supe with new IOS?
-Is there any command that i can use to switchover from active to standby supe??

I received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
In a redundant Sup-6E setup, the following configuration is supported :
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
If you invoke shared backplane mode, the following configuration can also be supported:
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
Here's the command and information about the "shared-backplane" mode :- [URL]
Currently, we have 2 SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:
1- One will be used to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
My questions are:
1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?

I have received a sup720-3B from Cisco with an internal 512MB flash(sup-bootdisk). I want to verify what IOS image is on the disk and do not have an spare 6509 chasis. Can I remove the 512 MB flash disk and insert it to my disk0: on my production 6509 with the sup32 that the 720 will repplace and view what is on the disk without corrupting?

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 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 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.

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.

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.

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.
