If you do not specify a native VLAN on the private trunk interface, all untagged packets
are dropped from the private VLAN trunk interface.
To configure native and allowed VLANs on a private VLAN trunk interface:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
4. Enter admin as the user name, enter your local device password, and click the Login
button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.
The System Information page displays.
5. Select Security > Traffic Control > Private VLAN > Private VLAN Trunk Interface
Configuration.
The Private VLAN Trunk Interface Configuration page displays.
6. Select whether to display physical interfaces, LAGs, or both by clicking one of the
following links above the table heading:
• 1 (the unit ID of the switch): Only physical interfaces are displayed. This is the
default setting.
• LAG: Only LAGs are displayed.
• All: Both physical interfaces and LAGs are displayed.
7. Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the port, or
type the port number in the Go To Interface field and click the Go button.
• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
The interface that you select must be configured either in Promiscuous Trunk mode
or Isolated Trunk mode (see Configure the private VLAN port mode on page 581).
8. In the Trunk Native VLAN field, specify a VLAN ID for a native VLAN.
By default, VLAN 1 is both the default and the native VLAN, but you can configure
another VLAN as the native VLAN (see Configure the switch port mode settings for
interfaces on page 196).
