Configuring a VLAN Chapter 6 Configuring VLANs Send feedback to [email protected] Note Commands entered in the VLAN configuration submode are immediately executed. Note VLANs 3968 to 4047 and 4094 are reserved for internal use; these VLANs cannot be changed or used. Configuring a VLAN This section includes the following topics: • Creating and Deleting a VLAN, page 6-4 • Entering the VLAN Submode and Configuring the VLAN, page 6-5 • Adding Ports to a VLAN, page 6-6 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 switch. 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. The traffic does not flow and the packets are dropped. To create a VLAN, perform this task: Step 1 Step 2 Command switch# configure terminal switch(config)# vlan {vlan-id | vlan-range} Purpose Enters configuration mode. Creates a VLAN or a range or VLANs. If you enter a number that is already assigned to a VLAN, the switch puts you into the VLAN configuration submode for that VLAN. If you enter a number that is assigned to an internally allocated VLAN, the system returns an error message. However, if you enter a range of VLANs and one or more of the specified VLANs is outside the range of internally allocated VLANs, the command takes effect on only those VLANs outside the range. The range is from 2 to 4094; VLAN1 is the default VLAN and cannot be created or deleted. You cannot create or delete those VLANs that are reserved for internal use. This example shows how to create a range of VLANs from 15 to 20: switch# configure terminal switch(config)# vlan 15-20 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide 6-4 OL-16597-01
