Huawei 3COM high-end Switch

Huawei 3COM high-end switches are described in detail, including software platforms, management methods, and subjective feelings. I have asked many people and have no satisfactory answers. Below is a similar answer to the question found on the Internet.

Software Platform

Compare Huawei 3COM high-end switches with Cisco switches, that is, the comparison between Cisco proprietary technology and industrial standards. Huawei's network management software consists of two parts: one is the network management platform and the other is the network management software. The network management platform is a third-party product. It can be selected from SNMPC, HP OpenView, and IBM NetView.

In a certain project, I used SNMPC5.0 in the Windows 2000 Server environment. The Network Management Terminal periodically polls network devices through the SNMP protocol to collect relevant information. One thing to note is that SNMPC 5.0 displays layer-2 content, which is not intuitive.

The second part is the network management software, which is the QuidView of Huawei's own product. NCV100R001 does not support vswitches 6506 and 2026 in this project. You need to upgrade to NCV200ROO1. QuidView, a network management software for Huawei 3COM high-end switches, provides simple functions, which are similar to CiscoView of CiscoWorks2000.

Management Method

Like Cisco devices, Intel switches provide a wide range of management methods, including Console, Telnet, Web, SNMP ...... With Intel's DeviceView, you can respond to the Bootp request of the device. It is especially convenient to set the switch for the first time.

From the perspective of Web management, Intel is more standard than Cisco devices, as long as the typical installation of IE is enough, there is no need to install Java Plug-ins, and the speed is fast. The interfaces of vswitches of different Intel models are consistent. Unlike Cisco, vswitches of different models are different.

In terms of VLAN implementation, Cisco trunk cable generally adopts ISL encapsulation (802.1q is also supported ). Because ISL is a Cisco Protocol, only 802.1q can be used for high-end Switches of Huawei 3COM. Cisco's Trunk cable is called "Trunk", Huawei's Trunk cable is also called "Trunk", and Intel's Trunk cable is called "Tagged Port", that is, Vlan tags are added to all frames on it, the common Port is the UnTagged Port.

In terms of VLAN settings, the implementation of Huawei 3COM high-end switches is cumbersome, such as full-network VLAN synchronization. Cisco has VTP, but the industrial standard GVRP is not implemented by the author. Cisco trunk cable belongs to all VLANs by default (1 ~ 1005), while Intel's trunk cable must be specified to a VLAN one by one.

Cisco can use a command: set VLAN3 1/1-2 to convert port 1/1-2 from VLAN1 to VLAN3. On an Intel device, you must not only delete the Port from VLAN1 and add it to VLAN3, but also set the Port VID, that is, the vlan id of the Port ). Therefore, it takes more time to set Intel vswitches.

VTP protocol is not supported on Huawei 3COM high-end switch 8016 devices, but VTP protocol is supported on its 6506, 3526, and 2026 devices. VLAN1 cannot be configured on V1. therefore, the network segment of the network management device must be adjusted to other VLANs other than vlan1. In this way, the management VLAN of the Trunk port should also be changed. Cisco uses native vlan commands, While Huawei uses default vlan commands.

The Cisco spanning tree is PVST, and each VLAN has its own spanning tree. Huawei is a standard single spanning tree (the same as Intel), but now the SPT Domain is introduced to solve the problem that the Spanning Tree is too big to be extended. Currently, Intel vswitches of all types support uplink ports of 1000Base-T, and their 470 and 480 devices support multiple 1000Base-T ports.

In terms of Optical Fiber Connection distance, Intel and Cisco are similar, but the automatic rate negotiation has some problems between some switches. For example, when the 480 460 Mbps Optical Fiber port is connected to, automatic negotiation should be disabled. Similar situations apply to the high-end Switches of Huawei 3COM. When 8016 of its 6506 Mbps Optical Fiber port is connected to, automatic negotiation should be disabled, otherwise, port 8016 may rise, but port 6506 may not start (the port light is not on, but the optical power machine has a normal optical signal after testing.

Subjective feelings

Cisco uses dot1q, unless it is a 1900 switch in the early stage. I feel that in the exchange field, Cisco adopts some proprietary technologies because the industrial standards are too late, so we can only use our proprietary technologies first. For example, the PVST + before the MISTP and The VTP before the GVRP. In general, Cisco has an absolute advantage in terms of VLAN manageability.

Now, Intel's switch has been discontinued, and the classic Intel DeviceView network management software is far away from us. However, as an Intel switch device that still occupies a considerable proportion in actual applications, it will still play an important role in a period of time.
