port private-vlan trunk secondary
Use port private-vlan trunk secondary to configure a port as a trunk secondary port of the
specified VLANs and assign the port to these VLANs.
Use undo port private-vlan trunk secondary to cancel the trunk secondary attribute of a port in the
specified VLANs.
Syntax
port private-vlan vlan-id-list trunk secondary
undo port private-vlan vlan-id-list trunk secondary
Default
A port is not a trunk secondary port of any VLAN.
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
Parameters
vlan-id-list: Specifies a space-separated list of up to 10 secondary VLAN items. Each item specifies a
secondary VLAN ID or a range of secondary VLAN IDs in the form of vlan-id1 to vlan-id2. The value
range for secondary 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 secondary VLANs that have been associated with primary VLANs, the
command also assigns the port to the associated primary 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 secondary VLANs and the associated primary VLANs as a tagged
member.
•
For a trunk port, the device does not change the port link type.
•
For a hybrid port, the device does not change the port link type.
If the port has been an untagged or tagged member of part of the secondary VLANs and
their associated primary VLANs, this member attribute remains in these VLANs. The device
assigns the port to the rest of the secondary VLANs and their associated primary VLANs as
a tagged member.
If the hybrid port does not allow any of the secondary VLANs and their associated primary
VLANs, the device assigns the port to these VLANs as a tagged member.
A trunk secondary port can join only one secondary VLAN among all secondary VLANs associated
with a primary VLAN. However, it can join multiple secondary VLANs separately associated with
multiple primary VLANs.
The undo form of this command does not change the VLAN attributes (allowed primary VLANs, port
link type, and PVID) of the port.
When you execute the undo form of this command on a trunk secondary port of the VLANs specified
by the vlan-id-list argument, one of the following events occurs:
•
If the port is an access port, the device does not change the VLAN configuration of the port.
•
If the port is a trunk or hybrid port, the device removes the port from the VLAN.
