Dell S4048-ON, Configuration Manual

Page: 46 / 1039

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.
Default Configuration
Although a version of Dell Networking OS is pre-loaded onto the system, the system is not configured when you power up the first
time (except for the default hostname, which is
Dell
). 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 following command.

Accessing the System Remotely
You can configure the system to access it remotely by Telnet or 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 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. Configure the Management Port IP Address
2. Configure a management route with a default gateway. Configure a Management Route
3. Configure a username and password. Configure a Username and Password
