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 shows this

information.)

• 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.
