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 congure them with the Dell Networking Operating Software (OS).

Interface Auto-Conguration

An Aggregator auto-congures 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 xed 40GbE ports on the base module operate in 4x10GbE mode with breakout cables and support up to

eight 10GbE uplinks. You can congure the base-module ports as 40GbE links for stacking.

– The interfaces on a 40GbE QSFP+ FlexIO module auto-congure to support only 10GbE SFP+connections using 4x10GbE

breakout cables.

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

– The tagged Virtual Local Area Network (VLAN) membership of the uplink LAG is automatically congured based on the

VLAN conguration of all server-facing ports (ports 1 to 32). The untagged VLAN used for the uplink LAG is always the

default VLAN 1.

– The tagged VLAN membership of a server-facing LAG is automatically congured based on the server-facing ports that are

members of the LAG. The untagged VLAN of a server-facing LAG is auto-congured based on the untagged VLAN to which

the lowest numbered server-facing port in the LAG belongs.
