2014 年 11 月 14 日 星 期 五 Huawei Sx700 Switches Interoperability Solution
Interoperability with Products from Other Vendors ---- Sx700 switches are developed in strict compliance with International standards and regulations. ----Sx700 switches have been widely deployed and interoperating with non-huawei products all over the world. Huawei is one of the Top 3 ICT manufacturers that provides more than 180 types of devices including core routing switches, GE access/aggregation switches, GE and 100M access switches, and full series small and medium switches. Currently, there are 6.5 million Huawei switches interoperating properly with non- Huawei devices globally. Huawei switches are developed in compliance with national/international standards and regulations, and can interoperate with any products as long as they comply with national/international standards. See the following lists for the corresponding national/international standards. Core switches Aggregation switches Access switches 1
Interoperability Testing: ----Verified by third-party certification authority Miercom. ----Interoperability test reports from multiple customers in China Miercom is an independent and leading and authoritative certification center. Its testing results of Huawei Sx700 switches demonstrated their high performance and powerful interoperability with non-huawei mainstream software and hardware. Interoperability tests were also conducted by China's Qihoo 360, proving that Huawei products are fully interoperable with Juniper, Cisco, and other mainstream vendor products. 2

Interoperability in Forwarding Interoperability in forwarding ensures that Core switch S9700 MAN packets can be successfully forwarded by VOICE interfaces on devices of different vendors. Aggregation layer S5700 Access layer S2700/ S3700 Aggregation layer 3750 Access layer 2960 Huawei products are developed in strict compliance with IEEE802.3i (10BASE-T), IEEE 802.3u (100BASE-T), Gigabit Ethernet (IEEE802.3ab ), Gigabit Ethernet (IEEE802.3z), IEEE 802.3ae (10GE) protocols, and all IP terminal PC ATM Query machine their interfaces are interoperable with non-huawei devices. 4
Interoperability in Controlling Standard protocol interoperability Interoperability in control plane means interoperability of Layer 2 and Layer 3 protocols, which prevents network flapping to ensure stable network. There are standard protocol interoperability and non-standard protocol interoperability. Non-standard protocol interoperability As shown in the above left figure, the S9700, Juniper 4500, and S5700 use Open Shortest Path First (OSPF) protocols to communicate. The S6700 acts as the Layer 2 transparent transmission device. The S9700 and Juniper 4500 are configured with bidirectional forwarding detection (BFD) to achieve OSPF. Devices of different vendors on current networks run different proprietary protocols. Huawei devices use various solutions to interoperate with non- Huawei devices to ensure network stability. As shown in the figure, ME3400 enabled with HSRP (Cisco virtual routing protocol) protocols and Huawei S5700 and S3700 enabled with BFD for VRRP can connect to each other to ensure network stability. 5
Cisco Proprietary Protocol Interoperability Solution PagP HSRP VTP A port that supports Cisco proprietary aggregation port protocol cannot communicate with a port that supports LACP. LACP aggregation can be used. The Cisco proprietary virtual routing protocol has a higher convergence ratio than VRRP. BFD for VRRP can be used, which is powerful than HSRP. Huawei can replace VTP with GVRP. Proprietary protocols are secluded protocols exclusive to a vendor. Cisco proprietary protocols make its devices incompatible with other devices. Flexlink PVST/PVST+ CDP IGRP/EIGRP UDLD Huawei provides SmartLink and RRPP that support multi-instance and 50-millisecond switchover. VLAN STPs can be replaced by MSTP. When Huawei devices are connected to Cisco devices, PVST packets can be transmitted transparently. Disadvantage of PVST: Too many protocol packets (Each VLAN has one PVST packet). Cisco access devices support only 128 PVST instances. Can be replaced by LLDP. If CDP protocol packets cannot be identified, the packets are transmitted transparently. Due to their low performance, distance vector routing protocols are now being replaced by mainstream IGP protocols such as OSPF or ISIS. Huawei provides DLDP with similar functions. However, the two cannot communicate. Ethernet OAM can also be used to provide similar detection function. Most vendors adopt standard protocols. Huawei devices use standard protocols and various solutions to replace Cisco protocols. 6

Interoperability of Management Interoperability in management means devices of different vendors can be managed in the same NMS to reduce maintenance costs. Huawei switches support SNMP V1/2/3 and over 50 standard MIBs including ENTITY-MIB, IF-MIB, and RFC1213-MIB, and can be managed by any third-party NMS that supports standard MIBs. See product MIB documents for details. Standard MIBs can only realize device management, alarm collection and management of some services. Complete management of non-huawei devices requires adaptation of proprietary MIBs of corresponding vendors. Core switches Aggregation switches Access switches 8

Overview of NetStream and sflow Traffic NetStream Two destinations NetStream supports traffic collection and aggregation based on flows and provides detailed data for accounting based on resource usage (such as the links, bandwidth, and time). This function provides key information for advanced network management tools to optimize network design and planning. Enterprises can use NetStream to achieve optimal network performance and reliability at the lowest cost. Currently, Huawei switches support NetStream V5/V8/V9, and esight supports only NetStream V5. sflow Datagram Sampled Flow (sflow), developed by InMon, monitors traffic forwarding sflow agent sflow collector on switches or routers of data networks. Currently, Huawei switches and esight support sflow V5. Traffic Client Client sflow datagram 11
NTA Network Traffic Analysis interoperability Huawei switches fully comply with standard RFC protocols to Collector Analyzer Analyzer encapsulate and send sflow and NetSream sampled packets. Third-party NMS uses the sampled packets to collect and analyze network traffic. According to applications on existing networks, Collector Huawei switches can connect to mainstream NMSs from device vendors in the industry, such as HP, H3C, and ManageEngine. S9700 Huawei switches can also connect to the network traffic analysis server VMware.
