Configuring Standard VLANs
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-
n
>
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.
