port trunk allow-pass vlan

Function

The port trunk allow-pass vlan command adds a trunk interface to the specified VLANs.

The undo port trunk allow-pass vlan command deletes a trunk interface from the specified VLANs.

By default, a trunk interface is in VLAN 1.

Format

port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] }&<1-10> | all }

undo port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] }&<1-10> | all }

(Port group view) port trunk allow-pass vlan vlan-id3 [ step step-number [ increased | decreased ] ]

(Port group view) undo port trunk allow-pass vlan vlan-id3 [ step step-number [ increased | decreased ] ]

Parameters

Parameter	Description	Value
vlan-id1 [ to vlan-id2 ]	Adds a trunk interface to specified VLANs. vlan-id1 specifies the start VLAN ID. to vlan-id2 specifies the end VLAN ID. The value of vlan-id2 must be greater than or equal to the value of vlan-id1.	The value of vlan-id1 is an integer that ranges from 1 to 4094. The value of vlan-id2 is an integer that ranges from 1 to 4094.
all	Adds a trunk interface to all VLANs.	-
vlan-id3	Specifies the ID of the start VLAN to be bound to the member port of a port group.	The value is an integer that ranges from 1 to 4094.
step step-number	Specifies the step for the increase or decrease in the value of the VLAN ID. With this parameter specified, the member ports in a port group can be bound to VLANs starting from the one identified by vlan-id3 in an ascending or descending order at a step specified by step-number. This facilitates the subsequent user configuration. For example: A port group has 10 member ports. You can configure increased, and set vlan-id3 to 1 and step-number to 1 in the port trunk allow-pass vlan command. After this configuration, member port 1 joins VLAN 1; member port 2 joins VLAN 2... By analogy, member port 10 joins VLAN 10.	The value is an integer that ranges from 1 to 4093.
increased	Specifies an increase in the values of VLAN IDs starting from the one identified by vlan-id3 at a step specified by step-number to bind the VLANs to the member ports of a port group.	By default, Layer 2 ports are bound to the VLANs in an ascending order.
decreased	Specifies a decrease in the values of VLAN IDs starting from the one identified by vlan-id3 at a step specified by step-number to bind the VLANs to the member ports of a port group. When setting decreased, ensure that the value of vlan-id3 is greater than or equal to the number of the member ports of the port group.	-

Usage Guidelines

Usage Scenario

A trunk interface can join multiple VLANs and connects to a network device. To allow all packets from one or more VLANs to pass through a trunk interface, the trunk interface must be added to the VLANs using the port trunk allow-pass vlan command.

Prerequisites

The link type of the interface has been set to trunk or negotiation.

Precautions

If a specified VLAN does not exist, the configuration does not take effect.

The command cannot be used on a member interface of an Eth-Trunk.

If you run the port trunk allow-pass vlan command multiple times in the same interface view, the interface is added to all the specified VLANs.

Example

# Add GE0/0/1 to VLANs 10 to 30.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port link-type trunk
[HUAWEI-GigabitEthernet0/0/1] port trunk allow-pass vlan 10 to 30
