You can now Telnet from any node in a stack to another node without having to re-enter your user credentials. When the target node accepts the related TCP connection, you are logged in to the same account (with corresponding rights) with which you accessed the originating slot.
Additionally, when Telneting to a switch from an external device, you can use the option -l username to provide your user name, rather than waiting to be prompted at login.
