Converting a Dynamic VLAN to a Static VLAN (CLI)
If a port on the switch has joined a dynamic VLAN, you can use the following command to convert that dynamic VLAN to a static VLAN:
static-vlan <dynamic-vlan-id>
Converting a dynamic VLAN 333 to a static VLAN
When converting a dynamic VLAN to a static VLAN as shown here, all ports on the switch are assigned to the VLAN in Auto mode.
switch(config)# static-vlan 333
