Users Guide

The untagged VLAN used for the uplink LAG is always the default VLAN.

Server-Facing LAGs

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 configured based on the untagged VLAN to which the lowest numbered server-facing port

in the LAG belongs.

NOTE: Dell Networking recommends that you configure the same VLAN membership on all LAG member ports.

Stacking Mode

When you configure an Aggregator to operate in stacking mode (See “Configuring and Bringing Up a Stack” in the Dell Networking

Configuration Guide for the M I/O Aggregator), VLANs are reconfigured as follows:

If an Aggregator port belonged to all 4094 VLANs in standalone mode (default), all VLAN membership is removed and the port is assigned

only to default VLAN 1. You must 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 mode only on the master switch

When you reconfigure an Aggregator from stacking to standalone mode:

Aggregator ports that you manually configured for VLAN membership in stacking mode retain their VLAN configuration in standalone

mode.

To restore the default auto-VLAN mode of operation (in which all ports are members of all 4094 VLANs) on a port, enter the auto vlan

command; for example:

Dell(conf)# interface tengigabitethernet 0/2

Dell(conf-if-te-0/2)# auto vlan

To get the default standalone mode configurations:

1 Delete the startup-config file and reboot the system.

2 Restore to factory default settings.

3 Configure auto vlan command on all the server ports.

Where to Go From Here

You can customize the Aggregator for use in your data center network as necessary. To perform additional switch configuration, do one of

the following:

• For remote out-of-band management, enter the OOB management interface IP address into a Telnet or SSH client and log in to the

switch using the user ID and password to access 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 VLAN IP address of the management port and log in

to the switch to access the CLI.

If you installed the Aggregator in a stack, you can configure additional settings for switch stacking

In case of a Dell Networking OS upgrade, you can check to see that an Aggregator is running the latest Dell Networking OS version by

entering the show version command. To download a Dell Networking OS version, go to http://support.dell.com.

Refer to the appropriate chapter for detailed information on how to configure specific software settings.
