Introduction This document illustrates how to configure Dell™ Force10™ S4810 switches for use with EqualLogic™ PS Series storage using Dell best practices. The recommended configuration uses link aggregation groups (LAGs) for inter-switch connections. Optional steps are provided in section 3 to enable Data Center Bridging (DCB).
Dell recommended switch configuration These steps show you how to configure two Force10 S4810 switches with a LAG. The switches are interconnected using two of the 40 GbE Quad Small Form-factor Pluggable (QSFP) uplink ports, and the LAG is configured for Dynamic Link Aggregation Control Protocol (LACP).
These commands configure the switch interconnect as a LAG.
