Concept Guide

The tagged VLAN membership of the uplink LAG is automatically congured based on the tagged and untagged VLAN conguration of all
server-facing ports (ports 1 to 8).
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 congured based on the server-facing ports that are members of
the LAG.
The untagged VLAN of a server-facing LAG is congured based on the untagged VLAN to which the lowest numbered server-facing port
in the LAG belongs.
NOTE: Dell Networking recommends that you congure the same VLAN membership on all LAG member ports.
Stacking Mode
When you congure an Aggregator to operate in stacking mode (See “Conguring and Bringing Up a Stack” in the Dell Networking
Conguration Guide for the M I/O Aggregator), VLANs are recongured 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 congure additional VLAN membership as necessary.
If you had manually congured an Aggregator port to belong to one or more VLANs (non-default) in standalone mode, the VLAN
conguration is retained in stacking mode only on the master switch.
When you recongure an Aggregator from stacking to standalone mode:
Aggregator ports that you manually congured for VLAN membership in stacking mode retain their VLAN conguration 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:
Dell(conf)# interface tengigabitethernet 0/2
Dell(conf-if-te-0/2)# auto vlan
The auto vlan command is applicable only in Standalone mode.
To get the default standalone mode congurations:
• Restore to factory default settings.
Where to Go From Here
You can customize the Aggregator for use in your data center network as necessary. To perform additional switch conguration, 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 congure 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.
