4.4.2.5 Syntax for Simultaneously Creating Multiple VLANs

It is possible to create multiple VLANs (at once) by specifying a range of VIDs rather than specifying a VLAN

name in the CREATE VLAN command:

CREATE VLAN VID {vid-range}

For n VIDs, the system will assign n VLAN names in the following format:

vlan<VID-1>

vlan<VID-2>

...

vlan<VID-

4.4.3 Configuring Standard VLANs

4.4.3.1 Default Configuration

•

As a default, there is one VLAN (VID 1), which cannot be created or destroyed.

• The default VLAN is associated with all Line Card interfaces and is in standard (non-UFO) mode.

• When creating a VLAN, its default forwarding mode is standard (non-UFO) and it is assigned to the default

STP.

• When an interface is added to a VLAN, it has untagged framing as its default with no VLAN translation.

4.4.3.2 Configuration Guidelines

•

The SBx3112 system supports up to 4094 VLANs and supports VLAN translation on all 4094 VLANs.

• Once an interface is added to a VLAN, it can only be associated with a single spanning tree.

• If adding interface that is part of a link aggregation group (LAG), all of the interfaces in the LAG must in the

same VLAN.

4.4.3.3 Configuration Procedure

The following procedure shows the commands used to create a standard VLAN, add an interface, and destroy

the VLAN.
