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.

Refer to the sw-dnld command for further information. set-tftp-srvr The set-tftp-srvr command sets the IP address of the TFTP server used for downloading.
Configuring, Modifying, and Monitoring the Unit 23 IP Commands This section lists the IP Configuration commands available at the CLI. It is separated into the following command sections: • IP configuration • Address Resolution Protocol (ARP) • Bootp • Ping To view the IP commands, enter IP at the CLI prompt.
Configuring, Modifying, and Monitoring the Unit 24 Setting an IP address set-ip The set-ip command sets the IP address of the SNMP Agent. If no IP address was previously set (as is the factory default configuration), the new value is used immediately and saved into NVRAM.
Configuring, Modifying, and Monitoring the Unit 25 Erasing an IP Configuration clear-ip-cfg The clear-ip-cfg command clears the NVRAM IP configuration. Example SYS_console>clear-ip-cfg Device IP Configuration cleared SYS_console> Configuring a Gateway get-gatew The get-gatew command shows the default gateway address.
Configuring, Modifying, and Monitoring the Unit 26 To activate/deactivate bootp use the following commands: set-bootp — Enables or disables the bootp process activation. get-bootp — Retrieves the state of the bootp process. Address Resolution Protocol (ARP) To view the ARP commands, enter ARP at the CLI prompt.
