Information
The VLAN:
• Can be in only one mode, either community, isolated, or primary.
• Mode can be set to community or isolated even before associating it to a primary
VLAN. This secondary VLAN will continue to work normally as a normal
VLAN even though it is not associated to a primary VLAN. (A syslog message
indicates this.)
• Must not have a port in it when the VLAN mode is being set.
Only ports (and port channels) configured as promiscuous, host, or PVLAN trunk
ports (as described above) can be added to the PVLAN. No other regular ports can be
added to the PVLAN.
After using this command to configure a VLAN as a primary VLAN, use the
private-vlan mapping secondary-vlan command to map secondary VLANs to this
VLAN.
