Interfaces

This chapter describes TenGigabit 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:

• Aggregator ports are numbered 1 to 12. Ports 1 to 8 are internal server-facing interfaces. Ports 9 to 12 are uplink ports.

• 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 8). 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.

• All interfaces are auto-congured as members of all (4094) VLANs and untagged VLAN 1. All VLANs are up and can send or

receive layer 2 trac. You can use the Command Line Interface (CLI) or CMC interface to congure only the required VLANs on

a port interface.
