Usage Guidelines

When you configure a port as a promiscuous private VLAN port and one of the following applies, the port becomes inactive:

•The port does not have a valid private VLAN mapping configured.

•The port is a Switched Port Analyzer (SPAN) destination.

If you delete a private VLAN port mapping or if you configure a private port as a SPAN destination, the deleted private VLAN port mapping or the private port that is configured as a SPAN destination becomes inactive.

See the private-vlan command for more information on promiscuous ports.


This example shows how to set a port to promiscuous mode for private VLANs:

switch(config-if)# switchport mode private-vlan promiscuous
