Cisco Switching/Routing :: Unable To Use Password On 2955
Apr 5, 2012
I'm been telnetting onto a 2955 and then upgraded the IOS and enabled ssh version 2 and then issues a "write", when I came back the exec-timeout had been issued and I was logged out of the router and now it is asking for a username and password and not just a password liek it did before enabling ssh. I havent yet put a username and password on yet, just the telnet.What would the username be if I havent set one?
I'm on a Cisco 2955 switch and need to get ssh working which I have done on another 2955 (but don't have near me), what am I doing wrong?
2955-02-PJ-CamdT.LU#sh run Building configuration... Current configuration : 4061 bytes!version 12.1no service padservice timestamps debug datetime msec [code]....
I'm about to configure radius on a 2960 and 2955 switch as I have been testing this on a 1841 router and to my dismay I can't see the options to configure radius, do these L2 switches not supoprt radius?
edit - apoligies I forgot the "aaa new-model" all ok now
I have installed Cisco 2955 Switch which already have x.x.x.x EA12 IOS and I copied x.x.x.x.EA13 into the flash: with intention to have EA13 enabled for IOS. I set the Global config for boot system by 'boot system (no falsh)x.x.EA13;x.x.EA12' but then also no luck and was showing EA12 in 'sh ver'. I then deleted the EA12 IOS and set the 'boot system flash:x.x.EA13'. I also had varified IOS EA13 by 'verify flash:IOS Filename', it verified the IOS.
But when I reloaded my switch, I'm unable to login and its in 'switch:' prompt (ROMmon mode - I believe). I then tried for flash_init, load_helper, dir flash: (showing me EA13 there) and finally boot flash:IOS Image file but no good news here... Output like this
Error loading "flash:IOS Image File EA13" Interrupt within 5 seconds to abort boot process. Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin"Interrupt within 5 seconds to abort boot process.
My guessing is that the IOS is corrupted (but its not showing me Error loading Image blabla...) I'm trying with EA14 of 4MB and I have 3 MB free spare and decided to remove EA13 first then through XModem try to upload EA14.
Any useful way and recommend me deleting EA13 and upgrading EA14... Also option to set boot image with having two IOS at the same time for permanent use.
I can't seem to send config changes to our syslog server on a 2950, I'm fine with 2960's and 3750's. The Cisco 2955 is using the latest IOS c2955-i6k2l2q4-mz.121-22.EA14.bin.
I come across to use the Catalyst Switch 2955 and it has two Relay Connector with one Major (MAJ) and one Minor (MIN) as below picture.There is command line to trigger these two Relay Connectors. As below command to set the Relay Connector to minor for monitoring the power supply: alarm facility power-supply relay minor
1. My questions are when there is power-supply faulty, the Minor Relay Connctor (right picture) will be short-circuited, right?
2. If we connector the two ports (ports 4 & 5 at the left picture) with a normal cable to drive an Alram Bell (in short-circuiled or closed loop situation), do we need an external power supply to the Alram Bell? Or there will be power supply from Catalyst 2955 to the Alram Bell as well?
I am having an issue with this device after setting the ip address and rebooting. I have tried renaming the config.text file without success. I have also tried the steps mentioned here: [URL]
I have found that the Catalyst 2955 series switches do not use an external MODE button for getting a switch into the switch: prompt, but they use a break sequence like routers do to get into Rommon state URL
So I was wondering if there is a similar mecanism that applies to other kind of Catalyst switches, like 2960, 3560 or 3750.
One of my clients is using Cisco catalyst 2955 industrial switch.I am doing the configuration for them and come across one setting of FCS Error Hysterasis Threshold. I know FCS is Frame Check Sequence.
I do not understand is what is the meaning the setting of Hysteresis in term of percentage stand for what purpose?For example, the default is 10 percent. If I set the value to be lower 5% and what is the impact on that? Is this more stringent than default of 10% or less stringent than default of 10%?
the other similar resolutions on the cisco/other website but none of them works for the Cisco 4506 switch I have.
1. Reboot
2. Press the "CTRL + C" button on the laptop to put the router into ROMMON mode.Result: Works fine and gets into the ROMMON 1 mode.
3. confreg 0x2142Result: This one does not work. confreg=0x2142 and that command is accepted by the switch but it does not tell us that we have to restart to make the changes. Now it goes ROMMON 2 mode.
4. resetResult: I type reset and the switches seems to be power cycled but it again goes to the password prompt which I dont know and this is the password that I am trying to recover or break.
Switch: WS-C3750X-48P (Stack with 2 Members) IOS: 12.2(58)SE2 Lic: IPBASEK9
[Code]....
Since i added another Member to the Stack, i'm facing the following problem: When i login with my tacacs user account, i will not be asked for the password. The same thing is for the tacacs account of my colleague, after entering the username he is logged in. It seems for me, that the passwords are cached only for this Switch.
We recently purchased Cisco 3560X Layer3 Switch. We need to perform simple Inter VLAN routing. We have configured VLAN1 (name-server_vlan) and VLAN2 (name- user_vlan). We have also assigned the Ports and IP address to both the VLANs. After assiging this if we plug Laptop A into VLAN1 then it doesnt communicates with Laptop B (btw, Laptop A is able to Ping VLAN2 Gateway ) in VLAN2 but on the other hand Laptop B is able to communicate with Laptop A and ping everything i.e. Gateway of VLAN1.
I have Cisco ME3400 series switch .Unable to login as i have no user name and password. I want to set the swirch to factory default but not found any nub to press.
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.
I have tried pressing the Reset button (within 5 secs) when the router power up. On my HyperTerminal, the image was loaded and the line interfaces were up. But when I press enter on HyperTerminal, there was no response.
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 trying to do password reset on a 506e that I got with the current password unknown. I've gone to the Cisco URL for the reset: [code]
I am using the correct bin file as I checked with my pix version. Also I CANNOT ping the firewall from a PCor system on the network, but CAN ping everthing from the PIX.I've tried using interface 1 but no go. Also I've checked the TFTP software (Solarwinds) is running fine and I've unblocked it in XP's firewall.
I have Cisco ASA 5510 series router which was handling by our one of our network admin who left without giving admin password. Now this is time to break the password . Since i don't know the admin password of the router , i don't how to handle few request. I am not a basically network admin guy to handle such things but i need to know how to break the password in order to do further requests. How to login router admin console without password or any chance to bring into default factory configuration.?
I have a cisco 2960 switch. Trying to recover a password. Have tried several different ways to recover it. I have let the switch load completely, then pressing the mode button waiting for the light to turn amber and then green. I also have held the mode button down, plugged the switch back in until the mode light turns from amber to green. Either way I will type flash_init. Then when I type load_helper I get a invalid command response. The command load_helper isn't even listed.
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 recently aquired a Cisco SGE2000 switch and the first thing I did was update to the latest firmware and change password. Now I cant login? Neither my admin / admin dosent work nor the new user I have created. Is there any characters that this dosesnt support like backslashes or forward slashes for password? If not then what can I do to get access to the switch again?
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.
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.
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.
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?
I recently configured a cisco 3750 switch for a stand alone network here at work, and on all our other switches and routers we use ACS to access everything. This switch being a stand alone I dont have that option.
So being like that I have to create everyone in the shop a username and password. Is there a way to prompt the user to change their password on their first login like you would with windows or such?
