S2700, S3700, S5700, S6700, S7700, and S9700 Series Switches Interoperation and Replacement Guide

This document provides typical configuration examples for interoperation between Huawei switches and mainstream IP phones, firewalls, routers, Microsoft NLB servers, multi-NIC servers, Cisco switches, and SolarWinds.

Interoperation and Replacement Solution 2: Replacement Solution of a Single Device


When replacing a single device, you need to configure the connected interface of the Cisco device as non-negotiation.

Configuration Notes

  • This example applies to all versions of S series switches.
  • During interworking and replacement of Cisco switches and Huawei switches, the encapsulation mode must be IEEE 802.1Q.

Networking Requirements

In Figure 5-2, three Cisco devices use DTP to dynamically negotiate link types of interfaces. One device is replaced by a Huawei S series switch, and the three switches need to implement Layer 2 connectivity.

Configuration Roadmap

  1. Manually configure link types of interfaces. DTP on Cisco switches and LNP on Huawei switches are both proprietary protocols, and cannot interwork. When Huawei switches are connected to Cisco switches, the link type of an interface cannot be negotiated dynamically.
  2. Manually configure link types of interfaces on two switches as trunk and specify the packet encapsulation mode on Cisco switches as IEEE 802.1Q.


  1. Manually change the link type of Fa0/2 on the Cisco switch to trunk. The configuration of two Cisco switches is the same.

    CiscoA# configure terminal
    CiscoA(config)# interface fastEthernet 0/2
    CiscoA(config-if)# switchport trunk encapsulation dot1q
    CiscoA(config-if)# switchport mode trunk  //An interface on a Cisco switch joins all VLANs by default, and does not need to be configured manually.

  2. Configure the link type of the interface on the Huawei S series switch as trunk.

    <Huawei> system-view
    [Huawei] interface GigabitEthernet0/0/2
    [Huawei-GigabitEthernet0/0/2] port link-type trunk
    [Huawei-GigabitEthernet0/0/2] port trunk allow-pass vlan 2 to 4094  //When the link type of an interface of a Huawei S series switch is configured as trunk, the interface joins VLAN 1 by default. You need to manually add the interface to VLANs 2 to 4094.

  3. Verify the configuration.

    • Run the show interfaces fastEthernet 0/2 switchport command to check whether the link type field on the Cisco switch is Administrative Mode: trunk.
    • Run the display interface gigabitethernet 0/0/2 command to check whether the link type field on the Cisco switch is Link-type: trunk(configured).
