Extreme Switch Telnet asks for Password First

[vaiku]

When i telnet to extreme switch it asks for password first.

Rather than asking for Username/Password.

Escape character is '^]'.

telnet session telnet0 on /dev/ptyb0

password:

vaiku,

If you try with a telnet client what is the behaviour?

If it is not the same the issue rely on the expect layer.

What you coud do there is check for the input “

telnet session telnet0 on /dev/ptyb0

password:” and if it occurs, just send a carriage return to go to the username password.

Could you share the login part of the script?

It's a expect script that does the login and port change.

if I telnet to the switch this is what I see.

Escape character is '^]'.

telnet session telnet0 on /dev/ptyb0

password:

enter key then it asks for sure name and password.

Is SSH enabled on those switches?

What is the behaviour with SSH?

Did you configured radius authentication?

Strange,

Are you using a specific telnet client sending the username automatically?

If so, could you test with a command line telnet connection?
