Deployment Guide

• 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 switch boots up.
The switch with the Dell Networking OS version 8.3.16.1 requires boot ash version 4.0.1.0 and boot selector version 4.0.0.0. The following
example shows the completed boot process.
