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 24 as the
uplink and ports 5-8 as the downlinks.
