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.
When you delete a VLAN, ports associated to that VLAN shut down. The traffic does not flow and the

Nexus 5020 switch, 512 VLANs are supported. If these switches are in a distribution network with other
switches, the limit remains the same.
On the Cisco Nexus 5010 switch and the Nexus 5020 switch, 512 VLANs are supported. If these switches
are in a distribution network with other switches, the VLAN limit for the VTP domain is 512. If a Nexus
5010 switch or Nexus 5020 switch client/server receives additional VLANs from a VTP server, they
transition to transparent mode
VLANs 1 to 1000.
Purpose
Enters configuration mode.

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
