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. Only the 40GbE ports on the base module can be used 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).
• The tagged VLAN membership of the uplink LAG is automatically configured based on the
VLAN configuration 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 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.
• All interfaces are auto-configured as members of all (4094) VLANs and untagged VLAN 1. All
VLANs are up and can send or receive layer 2 traffic. You can use the CLI or CMC interface to
configure 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. For port numbering of
Aggregator interfaces in standalone and stacking mode, see
