Depending on the range of the VLAN, you can configure the following parameters for VLANs (except the
default VLAN):
•
VLAN name
•
Shutdown or no shutdown
When you delete a VLAN, the ports associated with that VLAN are shut down and no traffic flows.
However, the system retains the VLAN-to-port mapping for that VLAN. When you reenable or recreate the
specified VLAN, the system automatically reinstates those ports to that VLAN.
To create a VLAN in global configuration mode, log on to the Cisco Nexus 5000 Switch and enter the
following commands:
switch> enable
switch# configure terminal
switch(config)# vlan {vlan-id | vlan-range}
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.
