Getting Started 11 This section describes how to connect to the management port, log into the Command Line Interface, and set the unit’s IP Address. Connecting to the Management Port With the product we supply a management cable. You can use it to get access to the management port.
Getting Started 12 NOTE: If the switch has no IP Address, then the provided IP Configuration changes the running parameters as well as the NVRAM-based database. If the switch was already configured, the command only changes the NVRAM database. Therefore, to use the new parameters you should reset the Switch, using the warm-reset command.
Using the Command Line Interface 13 This section describes how to use the Command Line Interface (CLI) to configure and manage the NH2025-10 switch. Command Conventions The following conventions are used within this guide to make understanding and using the CLI easier.
Using the Command Line Interface 14 Example SYS_console> ping 129.1.1.7 ? The unit displays the next level of parameters: ping IP traffic generator [arg #0] destination IP address [arg #1] number of packets to send or 0 for endless ping SYS_console> ping 129.
