Configuring VLANs

VLAN Ranges

the stations in the marketing department are assigned to another VLAN, and the stations in the accounting
department are assigned to another VLAN.
Figure 1: VLANs as Logically Defined Networks
VLANs are usually associated with IP subnetworks. For example, all the end stations in a particular IP subnet
belong to the same VLAN. To communicate between VLANs, you must route the traffic.
By default, a newly created VLAN is operational; that is, the newly created VLAN is in the no shutdown
condition. Additionally, you can configure VLANs to be in the active state, which is passing traffic, or the
suspended state, in which the VLANs are not passing packets. By default, the VLANs are in the active state
and pass traffic.
A VLAN interface, or switched virtual interface (SVI), is a Layer 3 interface that is created to provide
communication between VLANs. In order to route traffic between VLANs, you must create and configure a
VLAN interface for each VLAN. Each VLAN requires only one VLAN interface.
VLAN Ranges
The extended system ID is always automatically enabled in Cisco Nexus 9000 devices.
Note
The device supports up to 4095 VLANs in accordance with the IEEE 802.1Q standard. The software organizes
these VLANs into ranges, and you use each range slightly differently.
For information about configuration limits, see the verified scalability limits documentation for your switch.
This table describes the VLAN ranges.
