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 for VCMP and VTP

VTP and VCMP are proprietary protocols, and cannot interwork. Huawei switches and Cisco switches can be used on the entire network. Configurations can be performed on the switch that is directly connected to Huawei and Cisco switches to implement interworking between Huawei and Cisco switches. The following describes three types of hybrid networking models.
  • Hybrid networking 1: C-H Model

    In the C-H model, a Cisco switch directly connects to a Huawei S series switch that has no downstream Cisco switch connected.

  • Hybrid networking 2: C-H-C Model

    In the C-H-C model, a Cisco switch directly connects to a Huawei S series switch that has a downstream Cisco switch connected.

  • Hybrid networking 3: C-H-H-C Model

    In the C-H-H-C model, a Cisco switch directly connects to a Huawei S series switch, and another edge switch of the VCMP network connects to a Cisco switch.

Huawei switches can replace switches in a Cisco VTP domain.
  • Replacing the transparent switch

    In Figure 5-6, a Huawei S series switch replaces the VTP transparent switch on a Cisco network. After the replacement, you only need to create a VLAN manually on the Huawei S series switch and add interfaces to the VLAN. For details, see Huawei S series switch configuration in Hybrid networking 1: C-H model.

  • Replacing the client

    In Figure 5-7, a Huawei S series switch replaces the VTP client on a Cisco network. After the replacement, you need to configure the Huawei S series switch to transparently transmit VTP packets. For details, see Huawei S series switch configuration in Hybrid networking 2: C-H-C model.

  • Replacing the server

    In Figure 5-8, no VTP server exists in the VTP domain after a Huawei S series switch replace it. If the Cisco network runs VTP version 1 or 2, any Cisco switch can function as the VTP server. If the Cisco network runs VTP version 3 alone or with VTP version1, you need to find a switch running VTP version 3 and run the vtp primary vlan command to specify the switch as the VTP server to manage the VTP domain.

    The Huawei S series switch only needs to transparently transmit VTP packets. For details, see Huawei S series switch configuration in Hybrid networking 2: C-H-C model.
