Arista’s 7135 Connect Series of Layer 1+ switches are powerful network devices that allow for dynamic connections between various layer 1 components on the system, such as the front panel and FPGA. These connections are driven by an underlying CLOS network of crossbar switches. The following commands provide the ability to configure middle stage crossbar switches within the system to create dynamic layer 1 connections.
