Introduction

This document provides examples of configuring the port-based VLAN, super VLAN and private VLAN.

Prerequisites

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 VLANs.

 

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 hosts only in the same department can communicate with each other.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware

Software version

S6520X-HI switch series

S6520X-EI switch series

Supported in Release 1110P01

Procedures

1.     Configure Device A:

# Configure the ports Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/3 to operate in bridge mode.

<DeviceA> system-view

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

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

[DeviceA-if-range] quit

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

[DeviceA] vlan 100

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

[DeviceA-vlan100] quit

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

[DeviceA] vlan 200

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

[DeviceA-vlan200] quit

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

[DeviceA] interface ten-gigabitethernet 1/0/3

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

[DeviceA-Ten-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:

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

b.     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 or Host D. (Details not shown.)

# Verify that Host B and Host D can ping each other, but they both fail to ping Host A or Host C. (Details not shown.)

# Display information about VLANs 100 and 200 on Device A.

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

 VLAN ID: 100

 VLAN type: Static

 Route interface: Not configured

 Description: VLAN 0100

 Name: VLAN 0100

 Tagged ports:

    Ten-GigabitEthernet1/0/3

 Untagged ports:

    Ten-GigabitEthernet1/0/1

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

 VLAN ID: 200

 VLAN type: Static

 Route interface: Not configured

 Description: VLAN 0200

 Name: VLAN 0200

 Tagged ports:

    Ten-GigabitEthernet1/0/3

 Untagged ports:

    Ten-GigabitEthernet1/0/2

The output shows that:

·     Ten-GigabitEthernet 1/0/3 and Ten-GigabitEthernet 1/0/1 permit packets from 100 to pass through.

·     Ten-GigabitEthernet 1/0/3 and Ten-GigabitEthernet 1/0/2 permit packets from 200 to pass through.

Configuration files

Configuration files on both Device B and Device A are the same. The following configuration files use Device A as an example.

#

vlan 100

#

vlan 200

#

interface Ten-GigabitEthernet1/0/1

 port link-mode bridge

 port access vlan 100

#

interface Ten-GigabitEthernet1/0/2

 port link-mode bridge

 port access vlan 200

#

interface Ten-GigabitEthernet1/0/3

 port link-mode bridge

 port link-type trunk

 port trunk permit vlan 1 100 200

#

Example: Configuring the super VLAN

Network configuration

As shown in Figure 2:

·     Users in VLAN 2 access the network through Ten-GigabitEthernet 1/0/1 of Device A.

·     Users in VLAN 3 access the network through Ten-GigabitEthernet 1/0/2 of Device A.

·     Ten-GigabitEthernet 1/0/3 of Device A and Ten-GigabitEthernet 1/0/1 of Device B are in VLAN 20.

·     Users in VLAN 20 use the gateway address 192.168.2.1 and IP addresses on the IP network segment 192.168.2.0/24.

Configure a super VLAN to meet the following requirements:

·     Users in VLAN 2 and VLAN 3 use the gateway address 192.168.1.1 and IP addresses on the IP network segment 192.168.1.0/24.

·     Users in VLAN 2, VLAN 3, and VLAN 20 are isolated at Layer 2 but interoperable at Layer 3.

Example: Configuring the private VLAN

Network configuration

As shown in Figure 3:

·     The aggregation-layer device Device A assigns VLAN 10 to Device B. Hosts access the network through VLAN-interface 10.

·     Users connected to Device B are on the same subnet 10.0.0.0/24.

·     Host A and Host B are in the Marketing department. Host C and Host D are in the Finance department.

Configure the private VLAN feature to meet the following requirements:

·     Device A is only aware of the primary VLAN 10.

·     Hosts in the same secondary VLAN are interoperable at Layer 2.

·     Hosts in different secondary VLANs are isolated at Layer 2.
