4500: lost password after s/w update

Hello,



I have two 4500 swiches in a stack. Local user settings were like:



local-user user1

password cipher %:/T*Q#V5V9./a!1$H@GYA!!

service-type ssh telnet terminal

level 3

local-user user2

password simple 123

service-type ssh telnet

level 2



After I updated my switches' software from 3.03.00s56 to 3.03.02s56 I can't log on as user1: Username:user1

Password:

% Login failed!

Though the password is correct. I could only log on as user2.



How can I reset user1's password from level 2? What have I done wrong?

Hmmm.... I thought the 3.03.02s56 WAS the fixed version... Now I am confused.



I will see if I can find any more details.



Rob.

Re: 4500: lost password after s/w update

I looked back at old emails, here is a snippet from one that I thought was related to your problem... maybe not.



"Hi Rob



Yes, I saw the same results when I upgraded from 3.02 w/password (note: there was no password in the config file)

Upgrade to 3.03 - password was removed

reinstated the password at 3.03 - it is also in the config file at this point

upgraded to 3.3.2 - password is in tact. (however now not in the config file)



I need to run 1 more test to make sure the password is in a private-data.txt file, but I must do this from the console,which I can get to at lunch."



Maybe you can login as User2, then upgrade your level so you can then set the password for the User1 account from the command line. See the following from the command reference:





Command "super"

Syntax super

View User view

Parameters level: User level, in the range of 0 to 3.

Description Use the super command to switch from the current user level to a specified level.





Username:monitor

Password:

<213>

<213>super

Password:

User privilege level is 3, and only those commands can be used

whose level is equal or less than this.

Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE

<213>



<213>sys

System View: return to User View with Ctrl+Z.

local-user admin

password cipher NEW





This show you upgrading User2 for just this session, editing the SYS config, going to the other account, changing the password. Then you should be able to logout and come in as User1 with the NEW password and good to go.



Let me know if this helps, Please.



Rob.

Re: 4500: lost password after s/w update

Hello Rob. Thanks for your support, but

Command "super"

Syntax super

also doest'n work. I had a super password level 3 cipher "2Xa


I managed to log on to the switch as 'admin' with empty (default) password, not the password I have set for admin previously. I had to go to the switch with a notebook and a console cable, because admin has only service-type terminal.

Is this a bug or a feature? I found nothing about resetting passwords to their default values in the documentation.

Hello;

Personally capture all configuration and paste to

notepad and reset to switch with when booting switch via CTRL + B and follow the 4500 operational manual.

If Everything is ok paste to previous configuration to switch everything is that.

Re: 4500: lost password after s/w update

I have noticed that when you upgrade any 4500 5500 switches it seems to reset the password and the only way to changet it to console in and reconfigure the password manualy.
