private-vlan (VLAN view)
Use private-vlan to associate a primary VLAN with the specified secondary VLANs.
Use undo private-vlan to dissociate a primary VLAN from the specified secondary VLANs.
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

Predefined user roles

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.
When you execute the undo private-vlan command, follow these guidelines:
If you specify the secondary vlan-id-list option, this command dissociates the primary VLAN from the specified secondary VLANs.
If you do not specify the secondary vlan-id-list option, this command dissociates the primary VLAN from all secondary VLANs.
Examples
# Associate primary VLAN 2 with secondary VLANs 3 and 4.
<Sysname> system-view [Sysname] vlan 3 to 4 [Sysname] vlan 2 [Sysname-vlan2] private-vlan primary [Sysname-vlan2] private-vlan secondary 3 to 4
