The purehw command set is used to display the status and information of the physical hardware components of the FlashArray. The purehw list command, when filtered by --type eth, specifically lists the physical Ethernet ports. The output for these ports includes crucial physical layer details such as the current negotiated link speed (e.g., 10G, 25G, 100G), along with their status, type, and slot location. This is the correct command for viewing hardware-level port characteristics.

A. The pureport list command displays information about front-end host-facing Fibre Channel and iSCSI ports (WWNs, IQNs), not the physical properties of Ethernet ports.

B. The purenetwork eth list command displays the logical network configuration (IP addresses, services, MTU) of Ethernet ports, not their physical hardware status like negotiated speed.

1. Pure Storage, "Purity//FA Command Line Interface (CLI) Reference Guide," Section: "Hardware Commands," subsection "purehw list." The guide documents that the output for ports includes the 'Speed' attribute, showing the negotiated link speed.

2. Pure Storage Knowledge Base, Article "How To Check Port Status and Other Details from the CLI," explicitly provides purehw list as the command to check physical port attributes, including speed.
