2.1 Dell EMC recommended switch configuration
The steps in this section show how to configure two Dell EMC Networking S4048-ON or S4048T-ON switches
with a link aggregation group (LAG). The switches are interconnected using two of the 40 GbE QSFP ports.
The LAG is configured for Dynamic Link Aggregation Control Protocol (LACP). This example uses physical
ports 49 and 50 for the 40 GbE interconnect between the two switches.
Note: LAGs for inter-switch connections are mandatory for PS Series iSCSI SAN environments and optional
for SC Series iSCSI SAN environments.
