Example for Configuring Communication Between VLANs Using VLANIF Interfaces

Huawei AR150&160&200&1200&2200&3200 Series Enterprise Routers Configuration Guide - Example for Configuring Communication Between VLANs Using VLANIF Interfaces

Networking Requirements

As shown in Figure 1, Ethernet 2/0/1 of the Router is connected to the uplink interface of SwitchA.

On SwitchA, the downlink interface Ethernet 2/0/1 is added to VLAN 10 and the downlink

interface Ethernet 2/0/2 is added to VLAN 20.

PC1 in VLAN 10 and PC2 in VLAN 20 need to communicate with each other

Configuration Roadmap

The configuration roadmap is as follows:

1. Add Ethernet interfaces to the VLAN.

2. Configure VLANIF interfaces.

Procedure

Step 1 Configure the Router.

# Create VLANs.

<Huawei> system-view

[Huawei] sysname Router

[Router] vlan batch 10 20

# Add interfaces to the VLANs.

[Router] interface ethernet 2/0/1

[Router-Ethernet2/0/1] port link-type trunk

[Router-Ethernet2/0/1] port trunk allow-pass vlan 10 20

[Router-Ethernet2/0/1] quit

# Assign IP addresses to the VLANIF interfaces.

[Router] interface vlanif 10

[Router-Vlanif10] ip address 10.10.10.1 24

[Router-Vlanif10] quit                   

[Router] interface vlanif 20

[Router-Vlanif20] ip address 20.20.20.1 24

[Router-Vlanif20] quit

Step 2 Configure SwitchA.

# Create VLANs.

<Huawei> system-view

[Huawei] sysname SwitchA

[SwitchA] vlan batch 10 20

# Add interfaces to the VLANs.

[SwitchA-Ethernet2/0/1] port link-type access

[SwitchA-Ethernet2/0/1] port default vlan 10

[SwitchA-Ethernet2/0/1] quit

[SwitchA] interface ethernet 2/0/2

[SwitchA-Ethernet2/0/2] port link-type access

[SwitchA-Ethernet2/0/2] port default vlan 20

[SwitchA-Ethernet2/0/2] quit

[SwitchA] interface ethernet 2/0/3

[SwitchA-Ethernet2/0/3] port link-type trunk

[SwitchA-Ethernet2/0/3] port trunk allow-pass vlan 10 20

[SwitchA-Ethernet2/0/3] quit

Step 3 Verify the configuration.

On PC1 in VLAN 10, configure the default gateway address as the IP address of VLANIF 10 (in this example: 10.10.10.1/24).

On PC2 in VLAN 20, configure the default gateway address as the IP address of VLANIF 20 (in this example: 20.20.20.1/24).

After the configuration is complete, PC1 in VLAN 10 can communicate with PC2 in VLAN 20.

How to Configuring Local Traffic Mirroring of Huawei Router

Pre-configuration Tasks

Before configuring local traffic mirroring, complete the following task:

Ensuring that the link layer protocol status of ports is Up.

1 Configuring a Local Observing Port

Context

In local mirroring, the monitoring device is directly connected to the observing port.

Do not configure other functions on an observing port; otherwise, the mirroring function is

affected.

1 If other service packets are transmitted on the observing port besides the mirrored packets, the packet sources cannot be identified.

2 If congestion occurs on the observing port, mirrored packets may be discarded because of their low priorities.

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

observe-port interface interface-type interface-number

A local observing port is configured.

----End

2 Configuring a Traffic Classifier

Configure complex traffic classification by selecting proper traffic classification rules. For

details, see Configuring a Traffic Classifier in the Huawei AR150&200&1200&2200&3200

Series Enterprise Routers Configuration Guide - QoS.

3 Configuring a Traffic Behavior

By configuring the traffic behavior, the device mirrors all the packets matching traffic

classification rules to the observing interface.

Procedure

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

traffic behavior behavior-name

A traffic behavior is configured and its view is displayed.

Step 3 Run:

mirror to observe-port

Traffic matching the rules is mirrored to the specified observing port.

----End

4 Configuring a Traffic Policy

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

traffic policy policy-name

A traffic policy is created and its view is displayed.

Step 3 Run:

classifier classifier-name behavior behavior-name

The traffic policy is associated with the traffic classifier and the traffic behavior containing traffic mirroring.

In the preceding command, classifier-name specifies a traffic classifier. The value of this

parameter must be the same as the value set in 7.5.2 Configuring a Traffic Classifier. The

behavior-name parameter specifies a traffic behavior. The value of this parameter must be the same as the value set Configuring a Traffic Behavior.

----End

5 Applying a Traffic Policy

You can apply a traffic policy bound to traffic behaviors and traffic classifiers to a mirrored port. For details, see Applying the Traffic Policy in the Huawei AR150&200&1200&2200&3200 Series Enterprise Routers Configuration Guide - QoS.

6 Checking the Configuration

1 Run the display observe-port command to check the observing port.

2 Run the display traffic behavior { system-defined | user-defined } [ behavior-name ]

command to check the traffic behavior configuration.

3 Run the display traffic classifier { system-defined | user-defined } [ classifier-name ]

command to check the traffic classifier configuration.

4 Run the display traffic policy user-defined [ policy-name [ classifier classifier-name ] ]

command to check the traffic policy configuration.

5 Run the display traffic-policy applied-record [ policy-name ] command to check the

application record of a specified mirroring policy.
