Command History
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
A private-VLAN port cannot be a SPAN destination port.
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.
host Configure the interface as a private-VLAN host port. Host ports belong to
private-VLAN secondary VLANs and are either community ports or isolated
ports, depending on the VLAN that they belong to.
promiscuous Configure the interface as a private-VLAN promiscuous port. Promiscuous
ports are members of private-VLAN primary VLANs.
