1. 1 Huawei Confidential Huawei and Cisco Switches Interoperation VOICE  Over 6.5 million Huawei switches are operating on live networks and their good interoperability has been verified by many customers. An enterprise may have many Cisco devices running on its network. An enterprise customer's major concern in a network expansion project is how can new devices seamlessly interoperate with Cisco devices to reduce the OPEX. After nearly 20 years development, Huawei switches have been able to interoperate Cisco devices on the forwarding, control, and management planes.  Huawei products are developed in strict compliance with IEEE802.3i (10BASE-T), IEEE 802.3u (100BASE-T), IEEE802.3ab (Gigabit Ethernet), Gigabit Ethernet (IEEE802.3z), and IEEE 802.3ae (10GE) protocols, and all their interfaces are interoperable with other devices on the forwarding plane. Interoperability on the Forwarding Plane Interoperability on the Control Plane MAN Core S9700 IP terminal Aggregation S7700 Access S5700 PC ATM machine Aggregation C4500E Access C3750X Core C6500E Interoperability on the Management Plane  Interoperability with standard protocols on Cisco devices: It has been verified by many authoritative certification companies that Huawei switches are fully interoperable with Cisco devices. Huawei switches have passed interoperability tests conducted by Miercom, EANTC, Qihoo 360, and Tolly.  Interoperability with Cisco proprietary protocols: Huawei switches can interoperate with Cisco proprietary protocols by transparently transmitting Cisco protocol packets or using standard or Huawei proprietary protocols as substitutes. Open platform Any vendor Open platform Any vendor Flexible mechanisms Any device Flexible mechanisms Any device Simple deployment Visible service Simple deployment Visible service Multi-version Multi-customer Multi-version Multi-customer Any policy Smart control Any policy Smart control  Huawei eSight provides an open platform for uniform O&M of multi-vender devices. eSight is capable of managing over 130 models of Cisco devices. It supports both standard MIBs and user-defined management functions. Management Capabilities Device management, including CPU usage, memory usage, and temperature monitoring Interface management and interface traffic statistics collection Alarm management, NetStream, and topology management  Huawei switches can be managed by certified third-party network management systems.

Huawei &Cisco Interoperation Success Stories  Turkey AveA's campus network project : Huawei S9700 interoperated with Cisco C6509E through OSPF and used BFD to speed up OSPF convergence. Huawei S5700 and Cisco 3560 ran VRRP to implement redundancy protection. S5700 and Cisco 2960/3560 ran standard MSTP protocol to build a loop-free Layer 2 network and ensure stable Layer 2 service provisioning.  Thailand Triple T's campus network project : Cisco C3750 and Huawei S5352 switches constituted a Layer 2 network. C3750 switches ran Cisco proprietary PVST protocol to implement redundancy on the Layer 2 network. S5352 switches transparently transmitted PVST packets so that C3750 switches can calculate a spanning tree using transparently transmitted PVST packets.  Bank of China's converged campus network project : Huawei S5700/S3700/S2700 and Cisco C3750 switches constituted a Layer 2 network. They ran standard MSTP protocol to prevent loops on the aggregation and access layers. The loop-free Layer 2 network provided access to PCs, ATM machines, and query machines, and simplified network topology and service deployment.  China Telcom's HQ campus network ODS upgrade project : The gateway originally deployed on Cisco C3560 was moved to the S9300 CSS system newly deployed on the network. The S9300 switches worked as aggregation switches and used CSS technology to improve network reliability. Cisco 3560 and Huawei S9300 switches ran standard MSTP protocol to realize redundancy protection on the Layer 2 network, ensuring fast failover upon a link failure.  Lenovo Hong Kong's data center project : Huawei S9700 switches worked as core switches and used BGP and MPLS to communicate with Cisco C6509 switches in autonomous systems of different regions such as HK Lincoln office, Beijing hub, and HK old DC. This deployment provided high security and fast data switching for the data center of Lenovo Hong Kong.
