Cisco Switching/Routing :: 6509 Copy Sup Boot Flash To ATA Flash

Feb 26, 2012

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.

Unable To Clear Startup Configuration / NVRAM

Aug 14, 2012

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#erase nvram


each time IP addresses and things got cleared but other aspects did not which should have been. In the nvram there were several files:

Directory of nvram:/
126 -rw- 2143 <no date> startup-config
127 ---- 5 <no date> private-config
128 -rw- 2143 <no date> underlying-config
1 ---- 49 <no date> persistent-data
2 -rw- 0 <no date> ifIndex-table

Cisco Switching/Routing :: Catalyst Supervisor 32 NVRAM Location?

Feb 10, 2013

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.

I upgraded the IOS on my 887VA router which is not yet in service. The next day I did a cold boot and made some changes. 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?

Cisco Wireless :: Flash Image For Air BR1310G-A

Dec 22, 2012

I 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?

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.

D-Link DIR-601 :: Flash To Stock Firmware From Dd-wrt?

Dec 7, 2011

I 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.
