Cisco Switching/Routing :: Restore 881-SEC-K9 Factory Startup Configuration?
May 21, 2012
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?

while configuring my ASA 5505 I changed the IP address range of the internal network. Obviously I made an error because I cannot reach the box neither at the old nor the new address. How can I restore the interface and firewall definitions or reset the box to its initial state ? I found a doc how to reset the password, but not explaining how to restore the complete initial config.

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 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.

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?

my name is Nathan and I have ran into an issue with my LAN. I recently did a factory restore by pressing F11 at start up due to corrupted Windows files. Now that I have restored my computer, I get a "limited connectivity" to an "unidentified network" I tried all the Windows repair options, I powercycled my modem and my router and I unplugged and replugged my LAN cable.

I'm having trouble with an 800 series router. Work has borrowed it to me so i can practice for my icnd2 exam. Only problem is it has a username and password on it. I have been told i can wipe the device and start over. but i cant get in to the user mode or any mode's as i don't have the user name and password. Is there a way of resetting the router back to factory defaults with out logging in to it?

I found a Cisco 1711 router in our storage room and I want to factory restore it so we can mess around with it or use it as a backup.
I connected a console cable to it and in Hyperterminal on a Windows XP box I want to try the CTRL+BREAK sequence to clear it out. I'm not concerned with the current config or finding the password, I just want to wipe it like it's never been used before.
This is what I get:

I have installed DD-WRT firmware onto my new D-Link DIR-615. It causes some problems and I'd like to re-flash router with orginal firmware. After turning router on with Emergency Room mode and choosing right (as for me) image file I'm getting "Unable to upload the image, please make sure the uploaded file is the correct image." Information.
Firmware downloaded from: [URL]
How can I fix my router? Which firmware file will be correct if not an original?

I currently have 2 cisco aironet 1121G access points. Both of which I believe had an image fail during an upgrade from autonomous mode to lightweight mode. I have tried to reset these access points as directed from Cisco's instructions. I have done a reset (amber light on the middle) and a factory restore (red light in the middle) They go through the steps to restore to factory default, however, after what I believe is an attempt to pull a dhcp address before defaulting into 10.0.0.1 ip address, the access point restarts. This is happening to both of them. After they reset and go through the series of memory tests, I am able to get all three solid green lights, they stay lit for just 15 seconds (rather than 5 minutes so that i can load a new image) I am not sure why they are behaving this way. I have tried as many different possibilities resetting with the mode button. There is no console port on this model of access points so i am unable to manage it otherwise.

I have a Catalyst 3560-X PoE that suddenly stopped working. I plugged in via console and below is the output I received. It scrolls constantly and I am unable to enter ROMMON mode or stop it from scrolling. I've read of a possible problem with the IOS version but I'm unable to verify due to not being able to stop the scrolling.

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.

We have recently purchased 2 x 4900M switches with the following configuration:
2 x X2-10GB-SR installed in port te1/1, 1/2 (optical)
1 x 20 x 1GB RJ45 installed in the top left of chasis ge2/1 - 2/20
1 x WS-X4908-10G-RJ45 8 port 1/2 card in the top right of chassis te3/1 - 3/8
We have te1/1 connecting the 2 switches, and various vlan's and connections on the 1GB RJ45's with no problems.
However, we have a number of 10Gbps BaseT connections te3/1 - te3/5 which are causing us issues. On a reload of the switch or removal / re-install of the cable it can take anywhere up to an hour for the port to become active again. So when we reload the switch, we may get a connection come up after say 3 mins, but the port next to it may not come up for 15-60 min. The cabling is all the same (CAT6 and has been tested/verified) and all connections go to Broadcom 10Gb cards in Dell 820 servers running vmware. We have the following set on the ports:
switchport mode access
spanning-tree portfast
No speed or duplex can be set on these ports - these options are not available in the config.
Once a link is finally established, it will hold the link solid with no problems, but this is a problem for us, we can't have a reboot take an undetermined amount of time for the link to come back.

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?

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 need to backup my ASA 5505 configuration and restore it to default, then I'll configure manually the new config, but if something doesn't work I want to restore the backup made before.
I tried the "copy run tftp" command, and it always answers the same: Result of the command: "copy run tftp" [code] I read everywhere its supossed to prompt asking me tftp server address and file name.

One of our costomers has a SRW224G4 Switch - which has not any documentation :-(
I do not get onto the switch in any way. I do not have an IP-Address, the default settings for he serial port do not work ... So I cannot reach the device and reset the password like described in: [URL]
Is there any other way to reset the device? I cannot find any reset button.

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 am in the process of setting up an interop lab for some engineers. The enviornment will consist of some 3750's, H3C's and ProCurves. My concern is that the end user will have Priv-Exec access for CLI usage on the 3750's and they can change the "en" password (I hope they don't but it has happened).Is there a way I can "break in" during the boot process to reset the password? The reason I am doing it this way is because I have an Altiris server with rebuild automation scripts in xpect and I would like to automate the process so I do not have to use a manual factory default reset.

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 tried this on 3 switches now all with the same result.... NO IP offered.

I recently decomissioned an 871 from a small business site and the owner did not want the device anymore. So now I'm trying to use it back at the office in the sandbox, however I don't know the password to the device and neither does the business owner. There's a reset button on the back, but from what I've read (here), it only loads a different config file found on the internal flash. Tried this, no dice. Is this essentially a bricked router now or is there anything else I can do to clear the config and repurpose it for my use?

I have a 3750G that used to be a Stack Master of a stack comprised of 2 identical switches. Since then, we have removed the stack from production, and I factory defaulted the stack MEMBER and that went fine. I just held the "Mode" button on the front until the lights all lit up and then issued the reload command and the switch came back with no configuration OTHER than the vlan database I issued the "del vlan.dat" command to no avail. I just manually removed all the vlans.
The stack MASTER on the other hand will NOT go back to factory defaults, and will also NOT erase the vlan database. Everything I try will NOT work. I've tried the following
1) Hold mode button & issue a reload after the lights start flashing
2) issue "Write Erase" then issue "reload"
3) issue "Write Erase", then issue "Write", then issue "reload"
4) issue "erase start" then issue "reload" (just in case the "write erase" command is being depriciated or something weird)
5) issue "erase start" then issue "copy run start" then issue "reload"
Is there a special way to reset a StackMaster back to factory defaults?
