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.
• 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.
• Aggregator ports are numbered 1 to 56. Ports 1 to 32 are internal server-facing interfaces. Ports 33 to 56 are external ports numbered
from the bottom to the top of the Aggregator.
