On an Arista 7150-24, which of the following commands would successfully help you to determine which ports would be subsumed within Ethernet1…

The Arista 7150 series switches are built on the Fulcrum Microsystems FM6000 (Alta) ASIC. These switches feature "agile ports," where four 10GbE SFP+ ports can be logically combined to function as a single 40GbE QSFP+ port. To determine the current mapping and see which physical 10GbE ports are subsumed by a logical 40GbE interface, the correct command is show platform fm6000 agile-port map. This command is a platform-specific verification command and is executed from the privileged EXEC mode (#), not a configuration mode.

B. Arista(config-if-Et1)#show platform fm6000 agile-port map

This is incorrect because show commands are typically run from privileged EXEC mode, not interface configuration mode.

C. Arista(config-mgmt-agile)#show platform fm6000 agile-port map

This is incorrect as config-mgmt-agile is not a standard or relevant configuration mode for this operation.

D. Arista(config-if-Et1)#show platform petra agile-port map

This is incorrect because the 7150 series uses the FM6000 ASIC, not the Petra ASIC, which is found in other platforms like the 7280R series.

Section: Chapter 10, "Platform Specifics" > Section 10.1, "7150S Series Switches" > Subsection 10.1.1, "Port Speed Configuration"

Content: This section explicitly states, "The show platform fm6000 agile-port map command displays the current mapping of physical SFP+ ports to logical 40G QSFP+ ports." All examples show the command being executed from the privileged EXEC prompt (Arista#).

2. Arista Networks, "Arista 7150 Series Data Sheet"

Section: "Arista 7150 Architecture"

Content: This document confirms that the 7150 series is "Powered by Arista EOS and the FM6000 1.28 Tbps switch-on-a-chip," verifying that fm6000 is the correct platform identifier for the command.
