• 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. Default Configuration Although a version of Dell EMC Networking OS is pre-loaded onto the system, the system is not configured when you power up the system first time (except for the default hostname, which is DellEMC). You must configure the system using the CLI. Configuring a Host Name The host name appears in the prompt. The default host name is Dell. • Host names must start with a letter and end with a letter or digit. • Characters within the string can be letters, digits, and hyphens. To create a host name, use the hostname name command in Configuration mode. hostname command example Dell(conf)#hostname R1 R1(conf)# Accessing the System Remotely You can configure the system to access it remotely by Telnet or secure shell (SSH). • The platform has a dedicated management port and a management routing table that is separate from the IP routing table. • You can manage all Dell EMC Networking products in-band via the front-end data ports through interfaces assigned an IP address as well. Accessing the System Remotely Configuring the system for remote access is a three-step process, as described in the following topics: 1 Configure an IP address for the management port.
