Interfaces

This chapter describes 100/1000/10000 Mbps Ethernet, 10 Gigabit Ethernet, and 40 Gigabit Ethernet

interface types, both physical and logical, and how to configure them with the Dell Networking Operating

Software (OS).

Interface Auto-Configuration

An Aggregator auto-configures interfaces as follows:

• All interfaces operate as layer 2 interfaces at 10GbE in standalone mode. FlexIO module interfaces

support only uplink connections. You can only use the 40GbE ports on the base module for stacking.

– By default, the two fixed 40GbE ports on the base module operate in 4x10GbE mode with

breakout cables and support up to eight 10GbE uplinks. You can configure the base-module ports

as 40GbE links for stacking.

– The interfaces on a 40GbE QSFP+ FlexIO module auto-configure to support only 10GbE SFP

+connections using 4x10GbE breakout cables.

• All 10GbE uplink interfaces belong to the same 10GbE link aggregation group (LAG).
