• To avoid denial of service (DoS) attacks, a rate-limit of 10 concurrent sessions per minute in SSH is devised. Therefore, you mightexperience 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 volumesof output, sometimes few characters from the output display are truncated and not displayed. This may cause one of the commands tofail 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, youcannot identify, whether a command has failed to be processed. The console output though is redirected back over SSH.Default ConfigurationAlthough a version of Dell Networking OS is pre-loaded onto the system, the system is not configured when you power up the system firsttime (except for the default hostname, which is Dell). You must configure the system using the CLI.Configuring a Host NameThe 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 exampleDell(conf)#hostname R1R1(conf)#Accessing the System RemotelyYou 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 Networking products in-band via the front-end data ports through interfaces assigned an IP address as well.Accessing the System RemotelyConfiguring 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. Configure the Management Port IP Address2 Configure a management route with a default gateway. Configure a Management Route3 Configure a username and password. Configure a Username and PasswordConfigure the Management Port IP AddressTo access the system remotely, assign IP addresses to the management ports.1 Enter INTERFACE mode for the Management port.CONFIGURATION modeGetting Started 49
