Configuration Limits for FC and FCoE, Cisco NX-OS Release 7.3(0)N1(1)

This chapter contains the following sections:

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.
