Overview
This document lists the Cisco verified configuration limits for fibre channel (FC) and fibre channel over
ethernet (FCoE).
In the following tables, the switch level (FC and FCoE) fabric level (mixed fabric) features, parameters, and
the verified scale values are listed. The numbers listed are for Cisco Nexus 5500, 5600, 6000 series switches
and the Cisco Nexus 5672-16G switch.
