VLAN C
OMMANDS
4-241
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. You must first enable Private VLANs with the pvlan
command, before configuring port members as shown in the following
example. 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
