Usage
Information
The VLAN:
• can be in only one mode, either community, isolated, or primary.
• mode ode to community or isolated even before associating it to a primary
VLAN. This secondary VLAN continues 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 VLAN mode is being set.
Only ports (and port channels) configured as promiscuous, host, or PVLAN trunk ports (as
previously described) 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.
