On a Nortel switch I went into the Nortel Device Manager and changed the security to ssh secure and now I cant ssh to it or even now use the gui to access it. On the Nortel Device Manager when I try to access it I get the following below. There is a route to the device, it is up and running fine, but no way to access it.
My ssh session conection to the nortel switch says:
Key exchange failed. No compatible cipher. The server supports these ciphers:
Thanks.
