Vlan Membership; Default Vlan - Dell PowerEdge M IO Aggregator Command Reference Manual

VLAN Membership

A virtual LAN (VLANs) is a logical broadcast domain or logical grouping of interfaces in a LAN in which
all data received is kept locally and broadcast to all members of the group. In Layer 2 mode, VLANs move
traffic at wire speed and can span multiple devices. FTOS supports up to 4093 port-based VLANs and one
default VLAN, as specified in IEEE 802.1Q.
VLANs provide the following benefits:
• Improved security because you can isolate groups of users into different VLANs
• Ability to create one VLAN across multiple devices
On an Aggregator in standalone mode, all ports are configured by default as members of all (4094)
VLANs, including the default VLAN. All VLANs operate in Layer 2 mode. You can reconfigure the
VLAN membership for individual ports by using the

Note: You can assign a static IP address to default VLAN 1 using the

If you configure an Aggregator to operate in stacking mode, only the default VLAN is supported. All ports
are automatically configured as untagged members of default VLAN 1. To configure additional VLANs in
stacking mode, use the

Default VLAN

When an Aggregator boots up, all interfaces are up in Layer 2 mode and placed in the default VLAN as
untagged interfaces. Only untagged interfaces can belong to the default VLAN.
By default, VLAN 1 is the default VLAN. To change the default VLAN ID, use the
