Introduction

The following information provides examples for VLAN.

Prerequisites

This document applies to Comware 9-based router. Procedures and information in the examples might be slightly different depending on the software or hardware version of the router.

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of VLAN.

Restrictions and guidelines: VLAN compatibility

This feature is supported only by Layer 2 interfaces.

Example: Configuring port-based VLANs

Network configuration

As shown in Figure 1:

·     Host A and Host C belong to Department A. VLAN 100 is assigned to Department A.

·     Host B and Host D belong to Department B. VLAN 200 is assigned to Department B.

Configure port-based VLANs so that only hosts in the same department can communicate with each other.

Software versions used

This configuration example was created and verified on R9141P16 of the MSR2630E-X1 device.

Procedures

1.     Configure Device A

# Batch set the link mode to bridge for GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3.

<DeviceA> system-view

[DeviceA] interface range gigabitethernet 1/0/1 to gigabitethernet 1/0/3

[DeviceA-if-range] port link-mode bridge

[DeviceA-if-range] quit

# Create VLAN 100, and assign GigabitEthernet 1/0/1 to VLAN 100.

[DeviceA] vlan 100

[DeviceA-vlan100] port gigabitethernet 1/0/1

[DeviceA-vlan100] quit

# Create VLAN 200, and assign GigabitEthernet 1/0/2 to VLAN 200.

[DeviceA] vlan 200

[DeviceA-vlan200] port gigabitethernet 1/0/2

[DeviceA-vlan200] quit

# Configure GigabitEthernet 1/0/3 as a trunk port, and assign the port to VLANs 100 and 200.

[DeviceA] interface gigabitethernet 1/0/3

[DeviceA-GigabitEthernet1/0/3] port link-type trunk

[DeviceA-GigabitEthernet1/0/3] port trunk permit vlan 100 200

2.     Configure Device B in the same way Device A is configured. (Details not shown.)

3.     Configure hosts:

¡     Configure Host A and Host C to be on the same IP subnet. For example, 192.168.100.0/24.

¡     Configure Host B and Host D to be on the same IP subnet. For example, 192.168.200.0/24.

Verifying the configuration

# Verify that Host A and Host C can ping each other, but they both fail to ping Host B.

# Verify that Host B and Host D can ping each other, but they both fail to ping Host A.

# Verify that VLANs 100 and 200 are correctly configured on Device A.

[DeviceA-GigabitEthernet1/0/3] display vlan 100

 VLAN ID: 100

 VLAN type: Static

 Route interface: Not configured

 Description: VLAN 0100

 Name: VLAN 0100

 Tagged ports:

    GigabitEthernet1/0/3

 Untagged ports:

    GigabitEthernet1/0/1

[DeviceA-GigabitEthernet1/0/3] display vlan 200

 VLAN ID: 200

 VLAN type: Static

 Route interface: Not configured

 Description: VLAN 0200

 Name: VLAN 0200

 Tagged ports:

    GigabitEthernet1/0/3

 Untagged ports:

    GigabitEthernet1/0/2

Configuration files

The configuration on Device B is the same as that on Device A. The following is the configuration file for Device A.

#

vlan 200

#

interface GigabitEthernet1/0/1

 port link-mode bridge

 port access vlan 100

#

interface GigabitEthernet1/0/2

 port link-mode bridge

 port access vlan 200

#

interface GigabitEthernet1/0/3

 port link-mode bridge

 port link-type trunk

 port trunk permit vlan 1 100 200
