Huawei Sx700 Switches Interoperability Solution

1

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

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

their interfaces are interoperable with non-Huawei

devices.

Interoperability in forwarding ensures that

packets can be successfully forwarded by

interfaces on devices of different vendors.

5

Interoperability in Controlling

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.

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.

Non-standard protocol interoperability

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.

6

Cisco Proprietary Protocol Interoperability Solution

PagP

HSRP

VTP

Flexlink

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.

Huawei provides SmartLink and RRPP that support multi-instance and

50-millisecond switchover.

PVST/PVST+

CDP

IGRP/EIGRP

UDLD

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.

Proprietary protocols are secluded protocols

exclusive to a vendor. Cisco proprietary

protocols make its devices incompatible with

other devices.

Most vendors adopt standard protocols. Huawei

devices use standard protocols and various

solutions to replace Cisco protocols.

Interoperability in management means devices of different vendors can be

managed in the same NMS to reduce maintenance costs.

Core switches

Aggregation switches

Access switches

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.

sFlow Datagram

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.

Sampled Flow (sFlow), developed by InMon, monitors traffic forwarding

on switches or routers of data networks.

Currently, Huawei switches and eSight support sFlow V5.

Third-party NMS uses the sampled packets to collect and analyze

network traffic. According to applications on existing networks,

Huawei switches can connect to mainstream NMSs from device

vendors in the industry, such as HP, H3C, and ManageEngine.

Huawei switches can also connect to the network traffic analysis

server VMware.

Huawei eSight servers can not only support switches that support

both NetStream and sFlow protocols, but connect to Cisco

switches that support Cisco proprietary protocol NetFlow.

understanding of network status. In addition, the hospital is notified of network alarms through means such as SMS, email,

and audible and visual displays. The system helps locate and rectify faults quickly through alarm topology linkage. These

features significantly reduce the cost and complexity of network maintenance and help ensure reliable operation of the

BovenIJ healthcare network.

Background

BovenIJ was seeking a vendor that could offer a reliable network solution that implements unified management and reduces

operation and maintenance (O&M) costs. The two most important factors BovenIJ considered when selecting a network

solution were:

1. Simple management and operation: The solution had to be highly intelligent, easy to operate, and offer fine-grained

management.

2. Strong compatibility: The solution had to support third-party devices and manage the legacy 3Com network devices from the

original network.
