Interface Auto-Configuration

An Aggregator auto-configures 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

configured based on the VLAN configuration 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 configured based on the

server-facing ports that are members of the LAG. The untagged VLAN of a server-facing LAG is

auto-configured based on the untagged VLAN to which the lowest numbered server-facing port in

the LAG belongs.
