Introduction This document illustrates how to configure Cisco® Nexus 5548UP switches for use with EqualLogic™ PS Series storage using Dell™ best practices. The recommended configuration uses link aggregation groups (LAGs) and Virtual Port Channel (vPC) for inter-switch connections. Note: Cisco currently does not support iSCSI TLV, which is required by EqualLogic to support Data Center Bridging (DCB).
Dell recommended switch configuration These steps show you how to configure two Cisco Nexus 5548UP switches with a vPC interconnect. The switches are interconnected using four of the 10Gb ports configured as the vPC link. Hardware configuration Power on both switches 2.

2.14 Disabling DCB Note: With Cisco Nexus family products, there is no command to fully disable DCB functionality. Using the configuration steps in this document results in a proper non-DCB environment. However disabling LLDP support can effectively prevent the negotiation of DCB by preventing the transmission of DCBx frames.
