Before You Start | 7The untagged VLAN of a server-facing LAG is configured based on the untagged VLAN towhich the lowest numbered server-facing port in the LAG belongs.Tip: Dell Force10 recommends that you configure the same VLAN membership on all LAGmember ports.Stacking ModeStacking is supported only on the 40GbE ports on the base module. A single stack is limitedto two Aggregators in the same chassis. Up to three stacks are supported in an M1000echassis. To configure a switch stack, you must use the CLI. See Stacking for moreinformation.When you configure an Aggregator to operate in stacking mode, VLANs are reconfigured asfollows:• If an Aggregator port belonged to all 4094 VLANs in standalone mode (default), allVLAN membership is removed and the port is assigned only to default VLAN 1. Youmust configure additional VLAN membership as necessary.• If you had manually configured an Aggregator port to belong to one or more VLANs(non-default) in standalone mode, the VLAN configuration is retained in stacking modeonly on the master switch.When you reconfigure an Aggregator from stacking to standalone mode, Aggregator portsthat you manually configured for VLAN membership in stacking mode retain their VLANconfiguration in standalone mode. To restore the default auto-VLAN mode of operation (inwhich all ports are members of all 4094 VLANs) on a port, enter the auto vlan command; forexample:FTOS(conf)# interface tengigabitethernet 0/2FTOS(conf-if-te-0/2)# auto vlanWhere to Go From HereYou can customize the Aggregator for use in your data center network as necessary. Toperform additional switch configuration, do one of the following:• For remote out-of-band management, enter the OOB management interface IP addressinto a Telnet or SSH client and log in to the switch using the user ID and password toaccess the CLI.• For local management using the CLI, use the attached console connection.• For remote in-band management from a network management station, enter the IPaddress of the default VLAN and log in to the switch to access the CLI.If you installed the Aggregator in a stack, you can configure additional settings for switchstacking.
