Command Usage
A Private VLAN allows modification of the default VLAN to provide port-based
security and isolation between ports within the VLAN. Data traffic on the
downlink ports can only be forwarded to, and from, the uplink port. Private
VLANs and normal VLANs can exist simultaneously within the same switch.
Example
This example globally enables private vlan, and then configures ports 13 and 14 as
uplink ports, and ports 1-8 as downlink ports.
