Use undo private-vlan to dissociate the specified secondary VLANs from a primary VLAN.
Syntax
private-vlan secondary vlan-id-list
undo private-vlan [ secondary vlan-id-list ]
Default
A primary VLAN is not associated with any secondary VLANs.
Views
VLAN view
Predefined user roles
network-admin
Parameters
secondary 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
A primary VLAN can be associated with multiple secondary VLANs. When you execute this
command in the same VLAN view multiple times, all the specified secondary VLANs are associated
with the primary VLAN.
The configuration synchronization is triggered based on the interface configuration when the
following conditions exist:
•
This command is configured for a primary VLAN.
•
Ports on the device are promiscuous, trunk promiscuous, or host ports.
For more information, see the port private-vlan host, port private-vlan promiscuous, or port
private-vlan trunk promiscuous command.
When you execute the undo private-vlan command, follow these guidelines:
•
If you specify the secondary vlan-id-list option, this command dissociates the specified
secondary VLANs from the current primary VLAN.
•
If you do not specify the secondary vlan-id-list option, this command dissociates all secondary
VLANs from the current primary VLAN.
Examples
# Associate primary VLAN 2 with secondary VLANs 3 and 4.
<Sysname> system-view
[Sysname] vlan 2
[Sysname-vlan2] private-vlan primary
[Sysname-vlan2] private-vlan secondary 3 to 4
