Before You Start | 9The Aggregator also detects iSCSI storage devices on all interfaces and auto-configures to optimizeperformance. Performance optimization operations, such as Jumbo frame size support, STP port-statefast, and disabling of storm control on interfaces connected to an iSCSI storage device, are appliedautomatically.CLI configuration is necessary only when the configuration includes iSCSI storage devices that cannotbe automatically detected and when non-default QoS handling is required.Link AggregationAll uplink ports are configured in a single LAG (LAG 128). Server-facing ports are auto-configured aspart of link aggregation groups if the corresponding server is configured for LACP-based NIC teaming.Static LAGs are not supported.Tip: The recommended LACP timeout is long-timeout mode.Link TrackingBy default, all server-facing ports are tracked by the operational status of the uplink LAG. If the uplinkLAG goes down, the Aggregator loses its connectivity and is no longer operational; all server-facingports are brought down.Tip: If installed servers do not have connectivity to a ToR switch, check the Link Status LED of uplinkports on the Aggregator. If all LEDs are ON, check the LACP configuration on the ToR switch that isconnected to the Aggregator to ensure the LACP is correctly configured.VLANsBy default, all Aggregator ports belong to all 4094 VLANs and are members of untagged VLAN 1.You can use the CLI or CMC interface to configure only the required VLANs on a port.When you configure VLANs on server-facing interfaces (ports 1 to 32), you can assign VLANs to aport or a range of ports by entering the vlan tagged or vlan untagged commands in interfaceconfiguration mode; for example:Uplink LAGThe tagged VLAN membership of the uplink LAG is automatically configured based on the VLANconfiguration of all server-facing ports (ports 1 to 32).Note: You can also use the CMC interface to configure VLANs.FTOS(conf)# interface tengigabitethernet 0/2 - 4FTOS(conf-if-range-te-0/2-4)# vlan tagged 5,7,10-12FTOS(conf-if-range-te-0/2-4)# vlan untagged 3
