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#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
1 ---- 49 <no date> persistent-data
2 -rw- 0 <no date> ifIndex-table

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?

don't have an option to connect a console cable to my cisco router. The usb to serial converter will not work in windows7 only on XP.have physical access to my 881 Cisco Router. If I remember correctly these routers have a default ip address. This router is brand new, out of the box. I am thinking I can access it with the correct IP via network instead of console.

I have a Cisco 850 router that whas having problems getting an ip address via DHCP. I did some stuff on it but that didn't work, so I rebooted the router to go back to my last saved startup config. When I turned it back on and connected t othe CLI console I got the "Would you like to enter the initial configuration dialogue?" message. Thinikng I just forgot to save anything to the startup config I went through the initial set up again and made sure to save everything to the startup config. After going through the intial config and setting up a vlan to assign DHCP to clients I saved the config and rebooted, upon reboot and connecting to the CLI console I got the same "Would you like to enter the initial configuration dialogue?" message. Tryign the setup once more and making sure everything was saved to startup config I rebooted again just to make sure the changes would stick, and sure enough they didn't. Whay is the config not saving to the startup config?

I'm running LMS3.2 and RME 4.3.1. I deployed a netconfig job to our network which consisted of approximately 800 devices.The report said that the job completed successfully however some of the devices didn't save thier running config to startup.
Is it possible to add a command or issue another netconfig job just to save the running config, so I can identify if the job fails on some devices? Using the tick box in the netconfig job doesn't seem to alert you if its not successful.

We were having a discussion in my group about startup vs running configs, and how often some network managers forget to "click save" when they configure a switch. Is there a way to configure Ciscoworks to copy the running config to the startup?

Ive got a wireless router and until just recently my desktop was able to connect to my network automatically. I went into network settings and made sure the "connect automatically" was checked but it did nothing. I have to manually go in and connect every time even though it recognizes that there is a network to connect to.

There are two issues which are testing my resolve.
1) Bad Cryptochecksum Ignored error
2) Unable to boot to a save startup-config file.
I want to take the configuration from one ASA 5505 and move it to another ASA 5505. I copied the startup-config file from an ASA 5505 running asa821-k8.bin to an ASA running 8.222-k8 to flash using tftp. I set the boot config parameter on the new asa to flash:/startup-config which is the location of the startup file. If I use copy run start command, I over write the startup file. When I copy the startup configuration to the running configuration I get a Bad Cryptochecksum Ignored error and the startup file does not copy over to the running file. How can I resolve this issue?

I messed up the IOS on the flash of CISCO881-SEC-K9. On reboot it booted to ROMMON which allowed me to tftp up a working IOS c880data-universalk9-mz.151-4.M3.bin. Unfortunately somewhere in my playing around the default startup configuration factory loaded on the routerhas been erased. I can load a new a config on the device but as I'm using the router to learn its useful to have the original config load when I factory reset the device. What is the factory start up config?

I have pair of ASA 5550 and I am trying to copy a new config to my member1 (active) as the new configuration I want to use for the pair. I want to copy this to start-up config on member1 and then reload member1 and have it copy the same config to member2 (stdby). I guess I am trying to understand if I copy the configuration to member1 and reload it, member 2(stdby) will have become active and try to copy the old configuration to member1 which I do not want.
get the commands straight that I need to execute to make sure the new startup config gets to both members without being overwritten?

I have reconfigured the FEX numbers attached to a Nexus 5548 running on NXOS5.2 If I do show running-config the interfaces are not there anymore. But if I do show startup-config the old Fex interfaces still shows up. I did try write erase then saved the running-config and its still there.

cisco 2651XM router
IOS: c2600-adventerprisek9-mz.124-15.T8.bin
if I do #sh arp in the terminal with this router I see a rogue entry thus:
Internet 192.168.0.4 0 Incomplete ARPA
My whole LAN operates on 172.16.x.x/16, there are no 192.168.x.x devices connected. In the past I've had 192.x.x.x devices running but for a long time and the router has been restarted since then. I've tried several clear commands in the terminal but this entry is stuck there and I've also seen it in a wireshark scroll on a pc when monitoring the routers' adsl traffic - it shows up an an SNMP entry and I do use SNMP on my router, but that data goes to a 172.16.x.x. machine. How can I clean this entry out?

I was wondering if I can force catalyst 2960 to skip startup config stored in NVRAM and boot with no config everytime it is powered. I tried to find it on google and in cisco white papers but still no luck. I found only commands that begin with "set boot config-register ... ", but switch acts like it does not know these commands.

I have an 877W router that I would like to have a 2nd pre-configured backup for. I was thinking of getting another 870 series (probably an 877) router, as the more expensive wireless option is not actually required. Am I right to assume that I could simply copy the contents of my current config.txt file onto the second router?

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.

'm having problems accessing the configuration utility of the *second* router in my daisy chain. Here's my setup. I have one router (router 1) on ground floor which gets internet from the modem. That router is then plugged into the LAN port of a wireless router upstairs (router 2). My laptop is then plugged into another LAN port on router 2. This allows me internet access as intended. But I'd like to log into the the configuration utility of router 2. But when I type the IP address of router 2 into my browser (192.168.1.1), it takes me to the configuration utility of router 1. Router 2 is out of the box--I haven't done any configuration to it (for example, changing its static IP address).

We have an issue with our 6500 catalysts.
We are regularly seeing the error above on our cat6500 devices when executing a 'sh run ' command:
We've seen this error for quite some time but the frequency seems to be increasing up to the point where it becomes problematic now because backups and other automated actions are failing regularly.
We don't see multiple processes with the commando "sh config lock" at that time. But when we do a "sh users", we can see sometimes multiple users.
I supose it is possible for multiple users to do a logon at the same time, but not make changes at the same time.
We are using IOS s72033-ipservicesk9_wan-mz.122-33.SXI7.bin. It seems that all switches with these IOSses seem to have the problem. But in the bug toolkit I can't find any reference to a bug...

I have the issue of being unable to access my router configuration page. My standard gateway IP (83.226.48.1), does not work, resulting in "unable to connect". If I try with my IPv4-adress, it just comes out with a blank page (Mozilla Firefox and Internet Explorer).

The IT department in my university has installed enternet 300 on all of our pc's - we have to use this to log into the inter/intranet on the campus. According to them, it is not possible to have the computer automatically log onto the system. I looked into the program, however, and found a place to put ip addresses, account and password. Note: the IT department in my school works hard but it not known for developing complete knowledge about the platforms they work on - there are many.
Is this correct is it possible to put the program in the startup folder and let the computer log on automatically? To be honest, even though most systems on campus us win 2000, I thought win 2000 had the ability to do this (log on to a network) natively, so I am a little puzzled as to why they have this on the computer.

I have a 3750 stack of 4 switches that was installed about 2 years ago. Recently I was doing some work on the switch and realized that I am unable to save the config. I amobviously concerned that if the power fails or the switch reboots I will be reconfiguring it and that is not something I am interested in doing!
Here is the error that I am receiving:
switch#copy run startup-config
Destination filename [startup-config]?
