Usage Guidelines
A private-VLAN host or promiscuous port cannot be a Switched Port Analyzer (SPAN) destination port. If
you configure a SPAN destination port as a private-VLAN host or promiscuous port, the port becomes inactive.
Do not configure private VLAN on ports with these other features:
•
Dynamic-access port VLAN membership
•
Dynamic Trunking Protocol (DTP)
•
Port Aggregation Protocol (PAgP)
•
Link Aggregation Control Protocol (LACP)
•
Multicast VLAN Registration (MVR)
•
Voice VLAN
While a port is part of the private-VLAN configuration, any EtherChannel configuration for it is inactive
A private-VLAN port cannot be a secure port and should not be configured as a protected port.
