SSH to Extreme Switch fails, "Server signature does not match"

$

Hi all,

 

I'm trying to configure our SolarWinds CatTools 3.6 (Enterprise) to backup the configuration of our Extreme Switches (Summit X350).

Unfortunately I get an error when trying to connect to the switch, the following is from the Info Log:

"Failed to connect to <ip address>. Reason: (30015) Server signature does not match.. Giving up after 3 connection attempts."

These are new switches so there shouldn't be any old signatures, and that shouldn't be the problem anyway, right?

I can connect to the switch with putty.

I have three different ssh connection methods to choose from in the device configuration; SSH2, Extreme SSH2 and SSH2-nopty. I am a bit unsure about the difference between them but I have tried them all without succeeding.

Telnet works (if I allow it), but we need to use SSH.

Does anyone recognise this problem?

Please let me know if you need any more information from me.

 

Best regards,

Daniel
