PC 6248 - management interface (HTTPS, SSH) problem.
Hello,
I have an issue on my DELL Powerconnect 6248 with the management interface. I have configured SSH and HTTPS, it worked few days without problem, but now I can't access it.
My switch works fine (ping, traffic...etc), bit it's just for the management interface.
In SSH, I put my login and password, but after that, the screen is blocked...my password is ok, and I don't have warning.
In HTTPS, the page loads during few second, and after that I have a message saying that the connection was reset.
I have not tried in Serial, but I think it's my last solution.
Somebody knows this issue? How can I restart or reset this management interface?
Regard's,
No Events found!

If you are not able to access the switch remotely then you will need to connect physically to the console port for trouble shooting. I would suggest once you have access to consider updating the firmware and boot code if not current. Here is a link to the current firmware for the 6200 series.

Here is some information on the set up commands for remote connection and security. Please look thru and compare to what you have configured on your switch.
1. Define a user name and password to allow privileged level 15 switch access for a remote user (HTTP
and HTTPS).
In this example, the user name Dell, the password is Dell1234, and the privilege level is 15. Privilege
levels range from 1–15, with 15 being the highest level. Level 15 access is the only level of access for the
Web interface.
console#config
console(config)#username Dell password Dell1234 level 15
console(config)#ip http authentication local
console(config)#ip https authentication local
console(config)#crypto certificate generate key_generate
Generating RSA private key, 1024 bit long modulus
console(config)#ip https server
2. Define a user name and password to allow access for a local user—console, Telnet, or Web Server, for
example. The enable password for console, telnet, and SSH is tommy123, bobby123, and jones123,
respectively.
In this example, the user name is Dell, the password is Dell1234, and the privilege level is 15.
console(config)#username Dell password Dell1234 level 15
console(config)#aaa authentication login default local
console(config)#aaa authentication enable default line
console(config)#line console
console(config-line)#login authentication default
console(config-line)#enable authentication default
console(config-line)#password tommy123
console(config-line)#exit
console(config)#line telnet
console(config-line)#login authentication default
console(config-line)#enable authentication default
console(config-line)#password bobby123
console(config-line)#exit
console(config)#line ssh
console(config-line)#login authentication default
console(config-line)#enable authentication default
console(config-line)#password jones123
console(config-line)#exit
3. Save the running-config file to the startup-config file.
This ensures that the configuration just completed is the same if the switch is rebooted.
console(config)#exit
console#copy running-config startup-config
Hope this helps.
Keep us updated please.
