Configuration manual

Following are the points to remember, when you are trying to establish an SSH session to the device to
run commands or script files:
• There is an upper limit of 10 concurrent sessions in SSH. Therefore, you might expect a failure in
executing SSH-related scripts.
• To avoid denial of service (DoS) attacks, a rate-limit of 10 concurrent sessions per minute in SSH is
devised. Therefore, you might experience a failure in executing SSH-related scripts when multiple
short SSH commands are executed.
• If you issue an interactive command in the SSH session, the behavior may not really be interactive.
• In some cases, when you use an SSH session, when certain show commands such as show tech-
support produce large volumes of output, sometimes few characters from the output display are
truncated and not displayed. This may cause one of the commands to fail for syntax error. In such
cases, if you add few newline characters before the failed command, the output displays completely.
Execution of commands on CLI over SSH does not notice the errors that have occurred while executing
the command. As a result, you cannot identify, whether a command has failed to be processed. The
console output though is redirected back over SSH.
Boot Process
After you follow the Installation Procedure in the Getting Started Guide, the MXL switch boots up.
The MXL switch with the Dell Networking OS version 8.3.16.1 requires boot flash version 4.0.1.0 and boot
selector version 4.0.0.0. The following example shows the completed boot process.
