Command Usage
• A private VLAN provides 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.
• Entering the pvlan command without any parameters enables the
private VLAN. Entering no pvlan disables the private VLAN.
Example
This example enables the private VLAN, and then sets port 12 as the uplink
and ports 5-8 as the downlinks.
show pvlan
