Parameters
vlan-id-list: Specifies a space-separated list of up to 10 primary VLAN items. Each item specifies a
primary VLAN ID or a range of primary VLAN IDs in the form of vlan-id1 to vlan-id2. The value range
for primary VLAN IDs is 1 to 4094. The value for the vlan-id2 argument must be equal to or greater
than the value for the vlan-id1 argument. Though the system default VLAN (VLAN 1) is in the valid
value range, it cannot be configured in the command.
Usage guidelines
If the specified VLANs are primary VLANs that have been associated with secondary VLANs, the
command assigns the port to the associated secondary VLANs. Also, the following events occur:
•
For an access port, the device performs the following tasks:
Changes the port link type to hybrid. The PVID of the port does not change.
Assigns the port to the primary VLANs and the associated secondary VLANs as a tagged
member.
•
For a trunk port, the device does not change the port link type or PVID.
•
For a hybrid port, the device does not change the port link type or PVID.
If the hybrid port has been a tagged or untagged member of part of the primary VLANs and
their associated secondary VLANs, this member attribute remains in these VLANs. The
device assigns the hybrid port to the rest of the primary VLANs and their associated
secondary VLANs as a tagged member.
If the hybrid port does not allow any of the primary VLANs and their associated secondary
VLANs, the device assigns the port to these VLANs as a tagged member.
The undo form of this command does not change the VLAN attributes (allowed secondary VLANs,
port link type, and PVID) of the port.
If you execute the undo form of this command on a trunk promiscuous port, the command removes
the port from the VLANs specified by the vlan-id-list argument.
You can configure the VLAN as a primary VLAN before or after you execute the port private-vlan
vlan-id-list trunk promiscuous command.
The port private-vlan trunk promiscuous command is mutually exclusive with the port
private-vlan host, port private-vlan promiscuous, and port private-vlan trunk secondary
commands.
If multiple primary VLANs need to pass through the uplink port, use the port private-vlan trunk
promiscuous command to assign the port to these VLANs. The port can then transmit packets from
these primary VLANs with VLAN tags.
If only one primary VLAN needs to pass through the uplink port, use the port private-vlan
promiscuous command to assign the port to the VLAN. The port can then transmit packets from the
primary VLAN without VLAN tags.
Examples
In this example, VLANs 2 and 3 are primary VLANs. VLAN 2 is associated with secondary VLAN 20.
VLAN 3 is associated with secondary VLAN 30.
