Configuration Guide - Ethernet Switching

CloudEngine 8800, 7800, 6800, and 5800 V200R003C00

This document describes the configuration of Ethernet services, including configuring MAC address table, link aggregation, VLANs, MUX VLAN, Voice VLAN, VLAN mapping, QinQ, GVRP, VCMP, STP/RSTP/MSTP, VBST, SEP, RRPP, ERPS, LBDT, and Layer 2 protocol transparent transmission.

Example for Implementing Inter-VLAN Communication Using VLANIF Interfaces

Example for Implementing Inter-VLAN Communication Using VLANIF Interfaces

Networking Requirements

Users in a company use different services and locate at different network segments. Users who use the same service belong to different VLANs and they want to communicate with each other.

In Figure 5-25, User 1 and User 2 use the same service and need to communicate, but belong to different VLANs and are located on different network segments.

Figure 5-25 Networking diagram for implementing inter-VLAN communication using VLANIF interfaces

Configuration Roadmap

  1. Create VLANs on the switches for different users.
  2. Add interfaces to VLANs so that packets of the VLANs can pass through the interfaces.
  3. Create VLANIF interfaces and configure IP addresses for the VLANIF interfaces to implement Layer 3 communication.

To implement communication between VLANs, hosts in each VLAN must use the IP address of the corresponding VLANIF interface as the gateway address.


  1. Configure the Switch.

    # Create VLANs.

    <HUAWEI> system-view
    [~HUAWEI] sysname Switch
    [*HUAWEI] commit
    [~Switch] vlan batch 10 20
    [*Switch] commit

    # Add interfaces to VLANs.

    [~Switch] interface 10ge 1/0/1
    [~Switch-10GE1/0/1] port default vlan 10
    [*Switch-10GE1/0/1] quit
    [*Switch] interface 10ge 1/0/2
    [*Switch-10GE1/0/2] port default vlan 20
    [*Switch-10GE1/0/2] quit
    [*Switch] commit

    # Assign IP addresses to the VLANIF interfaces.

    [~Switch] interface vlanif 10
    [*Switch-Vlanif10] ip address 24
    [*Switch-Vlanif10] quit
    [*Switch] interface vlanif 20
    [*Switch-Vlanif20] ip address 24
    [*Switch-Vlanif20] quit
    [*Switch] commit

  2. Verify the configuration.

    Configure the IP address on user 1's host, configure the VLANIF 10 interface IP address as the gateway address.

    Configure the IP address on user 1's host, configure the VLANIF 10 interface IP address as the gateway address.

    After the preceding configurations are complete, User 1 in VLAN 10 and User 2 in VLAN 20 can communicate.
