Information About VLANs
You can use VLANsto divide the network into separate logical areas at the Layer 2 level. VLANs can also be considered as broadcast domains.
Any switch port can belong to a VLAN, and, unicast broadcast, and multicast packets are forwarded and flooded only to end stations in that VLAN. Each VLAN is considered a logical network, and packets destined for stations that do not belong to the VLAN must be forwarded through a bridge or a router.
This section includes the following topics:
•VLANs Overview
•VLAN Ranges
•Creating, Deleting, and Modifying VLANs
•High Availability
•Virtualization Support
VLANs Overview
Note VLAN Trunking Protocol (VTP)mode is OFF. VTP protocol data units (PDUs) are dropped on all device interfaces, which partitions VTP domains if other devices have VTP turned on.
A VLAN is a group of end stations in a switched network that is logically segmented by function or application, without regard to the physical locations of the users. VLANs have the same attributes as physical LANs, but you can group end stations even if they are not physically located on the same LAN segment.
Any switch port can belong to a VLAN, and unicast, broadcast, and multicast packets are forwarded and flooded only to end stations in that VLAN. Each VLAN is considered a logical network, and packets destined for stations that do not belong to the VLAN must be forwarded through a router.
Figure 2-1 shows VLANs as logical networks. In this diagram, the stations in the engineering department are assigned to one VLAN, the stations in the marketing department are assigned to another VLAN, and the stations in the accounting department are assigned to another VLAN.
Figure 2-1 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.
Note See the Cisco DCNM Interfaces Configuration Guide for complete information on configuring VLAN network interfaces and subinterfaces, as well as assigning IP addresses. This feature must be enabled before you can configure VLAN network interfaces.
VLAN Ranges
Note The extended system ID is always automatically enabled in NX-OS devices.
The device supports up to 4094 VLANs in accordance with the IEEE 802.1Q standard in each VDC. The software organizes these VLANs into ranges, and you use each range slightly differently.
Table 2-1 describes the VLAN ranges.
Table 2-1 VLAN Ranges
VLANs Numbers
|
Range
|
Usage
|
1
|
Normal
|
Cisco default. You can use this VLAN, but you cannot modify or delete it.
|
2-1005
|
Normal
|
You can create, use, modify, and delete these VLANs.
|
1006-4094
|
Extended
|
You can create, name, and use these VLANs. You cannot change the following parameters:
•The state is always active.
•The VLAN is always enabled. You cannot shut down these VLANs.
|
3968-4047 and 4094
|
Internally allocated
|
These 80 VLANs, and VLAN 4094, are allocated for internal device use. You cannot create, delete, or modify any VLANs within the block reserved for internal use.
|
Note VLANs 3968 to 4047 and 4094 are reserved for internal use in each VDC; you cannot change or use these VLANs.
The software allocates a group of 80 VLAN numbers for those features, like multicast and diagnostics, that need to use internal VLANs for their operation. By default, the system allocates VLANs 3968 to 4047 for internal use. VLAN 4094 is also reserved for internal use by the device.
Note See the Cisco NX-OS Multicast Routing Configuration Guide for information about multicasting and the Cisco NX-OS System Management Configuration Guide book for information about diagnostics.
You cannot use, modify, or delete any of the VLANs in the reserved group. You can display the VLANs that are allocated internally and their associated use.
Creating, Deleting, and Modifying VLANs
Note By default, all NX-OS ports are Layer 3 ports.
VLANs are numbered from 1 to 4094 for each VDC. All ports that you have configured as switch ports belong to the default VLAN when you first bring up the switch as a Layer 2 device. The default VLAN (VLAN1) uses only default values, and you cannot create, delete, or suspend activity in the default VLAN.
You create a VLAN by assigning a number to it; you can delete VLANs and move them from the active operational state to the suspended operational state. If you attempt to create a VLAN with an existing VLAN ID, the device goes into the VLAN submode but does not create the same VLAN again.
Newly created VLANs remain unused until Layer 2 ports are assigned to the specific VLAN. All the ports are assigned to VLAN1 by default.
Depending on the range of the VLAN, you can configure the following parameters for VLANs (except the default VLAN):
•VLAN name
•VLAN state
•Shutdown or not shutdown
Note See the Cisco DCNM Interfaces Configuration Guide for information on configuring ports as VLAN access or trunk ports and assigning ports to VLANs.
When you delete a specified VLAN, the ports associated to that VLAN are shut down and no traffic flows. When you delete a specified VLAN from a trunk port, only that VLAN is shut down and traffic continues to flow on all the other VLANs through the trunk port.
However, the system retains all the VLAN-to-port mapping for that VLAN, and when you reenable, or re-create, that specified VLAN, the system automatically reinstates all the original ports to that VLAN. The static MAC addresses and aging time for that VLAN are not restored when the VLAN is reenabled.
Note VLANs 3968 to 4047 and 4094 are reserved for internal use in each VDC; you cannot change or use these VLANs.
High Availability
The software supports high availability for both stateful and stateless restarts, as during a cold reboot, for VLANs. For the stateful restarts, The software supports a maximum of three retries; if you try more than 3 times within 10 seconds of a restart, the software reloads the supervisor module.
You can upgrade or downgrade the software seamlessly, with respect to VLANs.
Note See the Cisco NX-OS High Availability and Redundancy Guide for complete information on high availability features.
Virtualization Support
The software supports virtual device contexts (VDCs), and VLAN configuration and operation are local to the VDC.
Note See the Cisco DCNM Virtual Device Context Configuration Guide for complete information on VDCs and assigning resources.
Each VLAN must have all of its ports in the same VDC. If you do not have enough resources allocated to the VDC, the software returns an error message.
When you create a new VDC, the device automatically creates a new default VLAN, VLAN1, and internally reserves VLANs 3968 to 4047 and 4094 for device use.
One or more VLANs can be associated with a role to either allow or disallow the user to configure it. When a VLAN is associated with a role, the corresponding interfaces will also be subjected to the same check. For instance, if a role is allowed to access VLAN1, then that role also has access to the interfaces that have that VLAN. If an interface does not have the VLAN associated with a role, that interface is not accessible to that role.
Licensing Requirements for VLANs
The following table shows the licensing requirements for this feature:

Prerequisites for Configuring VLANs
The following are prerequisites for configuring VLANs:
•You must be logged onto the device.
•You must create the VLAN before you can do any modification of that VLAN.
Guidelines and Limitations
Follow these guidelines and limitations when configuring VLANs:
•The maximum number of VLANs per VDC is 4094.
•You cannot create, modify, or delete any VLANs that are within the group of VLANs reserved for internal use.
•VLAN1 is the default VLAN. You cannot create, modify, or delete this VLAN.
•VLANs 1006 to 4094 are always in the active state and are always enabled. You cannot suspend the state or shut down these VLANs.
Configuring a VLAN
This section includes the following topics:
•Creating and Deleting a VLAN
•Configuring or Modifying the Basic Settings for a VLAN
Note See the Cisco DCNM Interfaces Configuration Guide for information on assigning Layer 2 interfaces to VLANs (access or trunk ports). All interfaces are in VLAN1 by default.
Creating and Deleting a VLAN
You can create or delete all VLANs except the default VLAN and those VLANs that are internally allocated for use by the device.
Once a VLAN is created, it is automatically in the active state.
Note When you delete a VLAN, ports associated to that VLAN shut down. Therefore, no traffic flows and the packets are dropped. On trunk ports, the port remains open and the traffic from all other VLANs except the deleted VLAN continues to flow.
If you create a range of VLANs and some of these VLANs cannot be created, the software returns a message listing the failed VLANs, and all the other VLANs in the specified range are created.
You use the VLAN pane to create VLANs (see Figure 2-2).
