View 1 RepliesTrying 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 CISCO pix, version 525, today while trying to save the config, I am getting below error

I was working on a Cisco 2600 series router earlier today running IOS 12.4. I ran into an issue where I could not clear the startup-config. I tried:
router#erase startup-config
router#reload
router#erase nvram
router#reload
[code]....
each time IP addresses and things got cleared but other aspects did not which should have been. In the nvram there were several files:
Router#dir
Directory of nvram:/
126 -rw- 2143 <no date> startup-config
127 ---- 5 <no date> private-config
128 -rw- 2143 <no date> underlying-config

I have a Sup32 that I suspect has faulty NVRAM (e.g., I am unable to "wr mem" on the device - it states resource is busy but no other active connections exist). Prior to replacing the supervisor engine I'd like to take a crack at formatting NVRAM to see if it resolves the issue. This supervisor does not have a CF card installed, thus no Disk0:. Within the CLI, I am presented two options with the "format" command - bootflash: and sup-bootflash:. Bootflash: does not have any data on it, however, sup-bootflash: contains my IOS image. I believe that both of these locations are simply directories within NVRAM.

Then, when I wrote them this warning popped up which seems to imply I need to recreate my configuration from scratch in order to avoid potential issues.Is that the correct interpretation of this message/scenario?

I am using TFTPD32 to upgrade the IOS on a router. When I type in the commands copy tftp flash and enter all the necessary information, the router sits for a minute or so and then times out. There is no entry made in the log when it times out. copy flash tftp yields the same result. The fa 0/0 interface and the TFTP server are both on the same subnet and can successfully ping one anothe

View 10 Replies View RelatedI purchased a used AIR BR1310G-A--K9-R from a local high school that was rebuilding their athletic field. The AP was used for communications for their pressbox staff. The AIR BR1310G was part of the schools campus wide WiFi network and was upgraded to an lwapp image c1310-k9w8-m 12.4 3c JA. Our home sits on a large lot and I would like to convert the BR1310G back to an autonomous AP.
In order convert it back to an automonous AP, I will need the original image. The school used a contractor for their WiFi network and they do not have a backup of the original image. I do not have a service account with Cisco so downloading the autonomous image from the Cisco website is out. What are my options for either obtaining an image file or using the current managed image without a WLC?
I need to upgrade the compact flash memory on a 2821 router from 64 to 128, upgrade the ios, and re-script the router. So I'm wondering what is the correct sequence? With the router powered on, do i eject the existing flash, and install the new one or do I power down the router? Once the memory has been increased, then i can upload the new ios?

I am needing to upgrade the Flash card on our current ASA from 64mb to a 1GB card to make way from upgrading from 8.0 to 8.4. When i copy all the contents from the 64MB card through a card reader i am not getting the startup-config file copied over. I checked to make sure that all hidden files are shown, but i am not seeing it. I backed up the startup-config from the old 64mb card to a tftp server before switching the cards out. Is their something that i am missing?

What do we need to do to make this a usable CF? Do I just need to reload the ASA or do I need to format the CF. It has been inserted into the slot in the back of the ASA 5520 and we have ensured that is had been seated properly.

View 1 Replies View RelatedI recently updated my firmware to dd-wrt... now I would like to switch back to stock firmware. I don't like the fact that any change I make basically resets the router. Plus DD-WRT GUI is VERY slow for me?I've followed every tutorial on how to do this, but the router will not accept the stock firmware. I've gotten the image to upload (according to the browser), but at 100% the flashing orange light & globe light just continue to blink & do nothing. I never see the other lights "flash" confirming the upgrade has took. I've set my IP manually through "Network Connections>Properties>TCP/IPv4" before trying. I get to the emergency firmware page...set it upload Version A1. Sometimes it uploads...but like I said, it never takes.
