Administrator Guide

When you configure VLANs on server-facing interfaces (ports 1 to 32), you can assign VLANs to a port or

a range of ports by entering the vlan tagged or vlan untagged commands in interface configuration

mode; for example:

Dell(conf)# interface tengigabitethernet 0/2 - 4

Dell(conf-if-range-te-0/2-4)# vlan tagged 5,7,10-12

Dell(conf-if-range-te-0/2-4)# vlan untagged 3

NOTE: You can also use the CMC interface to configure VLANs.

Uplink LAG

The tagged VLAN membership of the uplink LAG is automatically configured based on the tagged and

untagged VLAN configuration of all server-facing ports (ports 1 to 32).

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.
