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 of Management
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.

Huawei switches fully comply with standard RFC protocols to
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,
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.

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.
