NMC-RX 7.3.x User Guide, Vol. 2 > Using Device Utilities > Overview

Overview

The NMC-RX device utilities are a group of common utilities that include:

• Remote Login—Enables you to log in to a remote system and use resources as if they were connected to your local system. You can use either Telnet or SSH for remote terminal connections. Telnet is a standard terminal emulation protocol in the TCP/IP protocol stack. Secure Shell Server (SSH) protocol version 2 is supported as a secure alternative to Telnet.
• Ping—Enables you to send an Internet Control Message Protocol (ICMP) echo request packet to an IP address that you specify.
• Traceroute—Traces the path a packet takes to a destination. A list of hosts that receive probe packets as they travel to the destination host is displayed in the order that the receiving hosts receive the packets. Traceroute is mostly used to debug routing problems between hosts.
• Config Save and Restore—Enables you to save, restore, and delete configuration files on a device.

Each utility is available in the Tools menu or on the pop-up menu of a selected device.

Both ping and traceroute commands can originate in two ways:

• From the NMC-RX host platform to a specified device address (default setting)
• From a specified device to an IP address
