FlexIO module interfacessupport 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 withbreakout cables and support up to eight 10GbE uplinks. You can configure the base-module portsas 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 theVLAN configuration of all server-facing ports (ports 1 to 32). The untagged VLAN used for theuplink LAG is always the default VLAN 1.• The tagged VLAN membership of a server-facing LAG is automatically configured based on theserver-facing ports that are members of the LAG. The untagged VLAN of a server-facing LAG isauto-configured based on the untagged VLAN to which the lowest numbered server-facing port inthe LAG belongs.• All interfaces are auto-configured as members of all (4094) VLANs and untagged VLAN 1. AllVLANs are up and can send or receive layer 2 traffic. You can use the CLI or CMC interface toconfigure 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 to56 are external ports numbered from the bottom to the top of the Aggregator. For port numbering ofAggregator interfaces in standalone and stacking mode, see Figure 4-2.Interface TypesThe following interface types are supported on an Aggregator.Interface TypeSupportedModes Default ModeRequiresCreation Default StatePhysical L2 10GbE uplink No No Shutdown (enabled)Management L3 L3 No No Shutdown (enabled)Port Channel L2 L2 No L2 - No Shutdown (enabled)Default VLAN L2 and L3 L2 and L3(VLAN 1)No L2 - No Shutdown (enabled)L3 - No Shutdown (enabled)Non-default VLANs(VLANs 2 - 4094)L2 and L3 L2 and L3 Yes L2 - No Shutdown (enabled)L3 - No Shutdown (enabled)
