Cisco Switching/Routing :: Password Recovery On 3600 Router?Dec 5, 2012
I'm using the ctrl-break sequence in hyperterminal during the the initial boot, and it's hanging.
I'm using the ctrl-break sequence in hyperterminal during the the initial boot, and it's hanging.
i just wanna know if it's possible to perform a router password recovery using the reload command and then issue the break sequence instead of doing an off/on on the power switch. i often find in the docs to use the latter.also, is there a way to retain the startup-config on a router when we re-enable the password recovery functionality (no service password-recovery). i've just tried this on one of our 877 and when i hit the break sequence, it went back to factory default setting.View 7 Replies View Related
I understand that the password has to be changed the first time we login to Cisco 3945 router but i failed to do that and its not allowing me to connect using default username/password.View 7 Replies View Related
I need to break into a 2901 router to recover the passwords. Cisco's methodology for password recovery on 2900 seriews routerssays to remove the compact flash card and reboot into RMON. There is no external compact flash card on a 2901. Is there acompact flash card inside the box? Or can you use the older method of rebooting and then hitting ctl+break to boot into RMON?View 5 Replies View Related
I am trying to use the password recovery for an NME-16 and am having trouble. I am unable to look at my files in dir to so I can rename them. I can get the switch to bypass the config and come with the switch: prompt, but can not do anything more. I am trying the password recovery guide, but cant get to the text file to rename. I am using a 2811 router.View 2 Replies View Related
I can see the console on the router. (Using the USB console connected to a Macintosh.) I was configuring the router though this console connection, and I created a new user (priv level 15) and removed the default 'cisco' user. So I'm stuck at the username/password login prompt now.
I decided to do the password recovery procedure (via the cisco doc I found etc), but I cannot break into ROMMON during the boot process. I'm not sure if that's because my Mac isn't sending the break, or what.
The pw recovery doc says you can "remove flash" if you can't break into the boot sequence. However, I cannot find any instructions on how to remove the flash. I've opened the router, and I see one very small daughter card on the main board that I think is the flash, but I'm not about to start arbitrarly prying parts off.

I have one CISCO 6509 Switch in my store. I tired to login in that switch but couldnt.. Once it's booted it's asking me: rd: . Find the attachment. I recover the password by changing confreg value but that also failed.View 8 Replies View Related
I have a major problem with our core 2801 router. In summary it appears that a staff member disabled password recovery, deleted the IOS and rebooted. Net result is no Rommon and no IOS on the flash. I've read that the Conf-Reg will be reset if I remove the NVRAM but I cannot identify it on the board. If I can get to Rommon I can recover. Currently I don't have Flash reader to restore to flash.View 2 Replies View Related
i read alot about password recovery , but when i apply it to cisco 7604 it fails ?i went to rommon mode and typed# confreg 0x2142 then i typed reset when the router startup it request a password form me ,i can enter the user mode , and when i type sh ver command i note that the config resgitser is 0x2102 , not 0x2142 !!!!
i could enter the privilage mode !!!! and seems no thing changed ! does this router has a specific password recovery procedure ? which differes than the classic procedure?
I have catalys 4507 with TWO supervisor V.I flowed this procedure : url...
after the reset normaly i can change the password and i check the confreg is 0X2142 but it still ask to enter the possword should i remove 1 supervisor and do the procedure or i must let the two spuervisor?
I have 2 x 6513 each with dual supervisor 720, and need to recover the enable password, is there a better method than removing one supervisor, disabling redundancy and performing password recovery on the single active supervisor module , before re-inserting the second supervisor and re-enabling SSO/RPR on the still active module.View 2 Replies View Related

I enabled the "no service password-recovery" command on my C2960 switch. All seems to work as discribed. Only issue I have is --- which show command is used to reveal if the password-recovery feature is enabled of disabled as the command doesn't show up in the running config after you enable it ?
NOTE: The command does show up in the C2960 switch in config t mode (unlike the IOS router 2800 series), but doesn't show up in the running-config after you enable or disable it.
On the 2800 series routers (latest IOS) in config t mode the command does not show up but if you type "no service passowrd-recovery" the command function correctly and it does list it in the running configuration.

Recently I have bought a 2821 router from an auction. The router did have some configuration and password on it. I tried to break into it by restating it and pressing control and pause break signal. Old cisco method. Now when I try this method on my 2821. It does say that password recovery is disabled on the router. After this message router proceed with normal boot process. How to break the password ? Even if I loose the configuration.View 4 Replies View Related
We have a cisco 2801 router in class which has a disabled password recovery. We tried almost everything, we cannot get into ROMmon and the break sequence doesn't work in any program (hyper terminal, putty, teraterm pro).
Here is the log from hyperterminal:

I'm working designing a switch system for our core/data center.
We have 5 esx hosts, 2 sans with 3 nodes each. We have voice servers, a couple of routers and a few odds and ends. There are 7 other locations aggregating into this data center via 1-2gbps fiber connections. The bandwidth usage on these links is minimal, but there is a total of about 3000 devices aggregating into the system. My main concern right now is the 3560G's are seeing many output drops, due to the small buffer size on those switches. I have been looking at couple of options to resolve this issue, including the 4948E, 4507E, and 3750X switches.
Budget being the biggest factor, I am finding that the 4507 might be out of the price range. So I was leaning towards the 4948E switches for connecting the servers and iscsi san's as the 3750X is not recommended for iscsi. Redundancy is important so I would like to have two. The second concern is that I need to aggregate the fiber connections and for that I was looking at the ME-3600X or possibly the WS-C3750X-12S-E. I'm running eigrp, so this switch would need to have full routing, as it would also serve as the core switch for the 4948E's.
So in the end I was thinking that two 4948E switches up linked to the ME-3600X which would do full routing for the fiber aggregation and any routing needed for the servers and sans.
Servers and Sans_________4948E________ME-3600X_________7 fiber connections
I would look at a second ME-3600X in the future for redundancy. This is the lowest cost biggest buffer solution that I could find.
I recently installed a couple of Cisco Aironet 3600 Series Wireless Access Points at a remote site. While I was at the site everything seemed OK, The clients were able to get connected to the access points, the guest network worked fine, I could SSH into the access points, and I could ping them. The problem is when I went back to my home site I tried to SSH into the access points through an ASA IPSec VPN Tunnel and it couldn’t find it. When I try to ping the access points they “time out”. I can ping and connect all other addresses (via RDP, HTTP, etc..) on the same subnet which should rule out an access list problem. A couple of notes to be aware of:
The WAP’s have the Autonomous IOS installed (Version 15.2(2)JB) The WAP’s are connected to Dell PowerConnect 5724 (Not by choice.. We are a Cisco shop, these were already there and have plans this year to replace)
I can ping and SSH with Putty to the WAP’s from the local subnet I cannot ping or SSH from a remote subnet to the WAP’s. I can access all other IP’s and Computers from a remote subnet.
I had to format flash and recover. I did the quicker way by using set BAUD 115200...once the .bin was across I forgot to set the baud back to 9600. I have followed instructions: go back to switch: set BAUD 9600 then reset. also tried the unset command. problem is it always comes back up with a BAUD of 115200. CWill I have to label 1 switch as 115200?View 38 Replies View Related

i have enabled error disbled recovery with time interval of 600 seconds on my 2960 switch.
What exactly this command does? Pls explain
I have the wrong code on the device. I can get to the switch: prompt. The manual say to connect a PC to the management port. But it does not come up. x modem does not seem to work. I found some commands :

I am a student pursuing a CCNA certification currently. I recently came across a lot of 3548 xl switches. They power up fine, post with out problem and load flash. The problem I am running into is that the console is password protected. I have found the password recovery procedure for this switch, but it requires the use of the mode button. I have tried this process several times and the flash file is loaded with the startup config file.

To configure my Cisco, I use the console cable but as I have no serial port on my PC, I use a USB to serial cable which I plug the console. I had lost this USB cable -> serial but I found another one. So I started to configure my Cisco by copying from an existing config. I found out that a prior the converter is defective and copy the wrong config.
I had copied the enable secret password and it badly copied! No luck, I made a copy run start. Therefore more accessible to Cisco! When I start the Cisco, I see what activated "the Mechanism password-recovery is enabled". so I followed the procedure Cisco

I have a couple of 877s which have "no service password recovery" set and something has happened to the flash or the IOS has been lost for one reason or another.
When trying to boot the routers, they all display similar to this, which then repeats:
Or words to the effect of there being no IOS at all, unable to boot, but the result is the same, it just loops and there's nothing I can do to break the sequence!
I've tried taking the flash from a working 877 and replacing the card but this doesn't work and unfortunately, putting the once working strataflash card back in the working 877, it gets the same problem!
I have a pair of 3560's configured with dot1q trunks between them carrying a number of VLANs.
Once deployed there will be a requirement for these physical trunks to be disconnected from time to time. Knowing that this is inevitable I am trying to minimise the period of time for the trunks to recover once the physical connectivity is reinstated.
All of the VLANs on the switches are configured for Spanning Tree Rapid PVST. Current time for the trunks/VLANs to come up is around the 4 second mark.
I am testing 2960 24 S with storm-control and Errdisable Port timer interval 60s , connected HUB on fa0/17 to make traffic / loop.After Strom Control detection the interface goes down thats ok after 60s they will try to recover the interface and going up although the loop is still there.For my understanding if the interface detect still a loop on that interface they will disable the port again for 60s and will check again.

I need to recover switch enable password, i have already configured AAA also, when i am tryig to follow below proceedure finally saying Authorization failed. how can i recover enable password,If I try to recover password like this description says [URL]
Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Power off the switch. Reconnect the power cord to the switch and, within 15 seconds, press the Mode button while the System LED is still flashing green.
Base ethernet MAC Address: 00:0x:xx:xx:xx:xx
Xmodem file system is available.
The password-recovery mechanism is enabled.
The system has been interrupted prior to initializing the flash filesystem. The following commands will initialize the flash filesystem, and finish loading the operating system software:

I was just configured a 3800 router with this command. I cannot get to the ROMMON mode anymore. Cisco says you should press Break key within 5 seconds after the image decompresses during the boot. But mine is ignoring it and going to load running config directly.View 7 Replies View Related
I have a 4404 running firmware 7.0 and something happened (don't think it was a hack), but all of a sudden I can't login to the box via web or ssh or even telnet.
In trying the recovery procedure, I get a lot of messages scrolling through and cannot do the Restore-Password command on the CLI.
I'm attaching the whole capture, but here's a truncated capture from the procedure:
*fp_main_task: Nov 21 10:39:46.501: sshpmGetCID: comparing to row 0, CA cert >bsnOldDefaultCaCert<
*fp_main_task: Nov 21 10:39:46.501: sshpmGetCID: comparing to row 1, CA cert >bsnDefaultRootCaCert<
So as you can see, my prompt to enter the command is taken up by this fp_main message and it uses up the first and only time I can enter this in. I'm trying everything I can to not have to go back to factory defaults.

I wanted to do with my Cisco 2800, a password recovery. I have read the instructions and Cisco just came up at six.
Complete these steps in order to recover your password:
Shut down the router. Remove the compact flash that is at the back of the router. Power on the router. Once the Rommon1> prompt appears, enter this command:
confreg 0x2142Insert the compact flash. Type reset.
BUT I had forgotten to plug the flash card. And now comes via console hieroglyphics only
I have 3 x ASA 5510 & 2 x ASA 5520, that require resetting back to factory default, the customer has removed the External Flash Cards, and i've checked internally on each unit the Internal Flash car is still present, is it possible to run a password recovery then a factory reset? and how would i go about resetting each unit to the new configuration.View 8 Replies View Related
