Precautions for setting Huawei switches compared with Cisco

Compared with Cisco, you should pay attention to setting up a Huawei switch so that you can easily avoid common problems and enjoy a smooth sailing when setting up a Huawei switch. How to Set Up A Huawei switch has become a concern. This article explains in depth the principles, ideas, and test process of the switch.

Compared with Cisco devices. The comparison between the two is actually a comparison between Cisco proprietary technology and industrial standards. First, let's talk about the network management software. Huawei's network management software consists of two parts: the first is the network management platform, which is a third-party product. It can include snnmpc, hp openview, and ibm netview.

This project uses the WINDOWS2000 SERVER Environment and uses SNMPC5.0. The principle is exactly the same. The Network Management end periodically performs round inspection on network devices through the SNMP protocol to collect relevant information. it should be noted that snmpc5.0 shows the pure layer-2 display of TOPO, which looks very inintuitive. Does HP's OPENVIEW and IBM's NETVIEW look like this?

The second part is the network management software part, which is the quidview of Huawei's product. Here, we need to note that NCV100R001 does not support devices and in this project and must be upgraded to NCV200ROO1. quidview is similar to the ciscoview function of CISCOWORKS2000. It implements panel capture and some related configuration and monitoring. In general, the functions implemented by Huawei's network management software are relatively simple, basically, it is equivalent to CISCOVIEW in CISCOWORKS2000.

Setting up a Huawei switch is the same as setting up a Cisco device. Setting up an Intel switch provides a wide range of management methods, including console, telnet, web, snmp... you can set the DeviceView of an Intel switch to respond to the Bootp request of the device. It is especially convenient to set the switch for the first time.

Compared with Cisco, it is more standard to set up the Web management of Intel vswitches, as long as the typical installation of IE is enough, without the need to install Java Plug-ins, the speed is also fast. The interface consistency between vswitches of different models is good. 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, Huawei devices can only use 802.1Q.cisco Trunk cable as Trunk, huawei's TRUNK cable is also called TRUNK, and the TRUNK cable of Intel's switch is called Tagged Port, that is, Vlan tags are added to all frames on it, and the common port is the UnTagged Port. in terms of Vlan settings, Huawei's implementation is cumbersome.

For example, for full-network Vlan synchronization, cisco has VTP, while industry-standard GVRP is not implemented. By default, cisco trunk belongs to all VLANs (1 .. 1005), and the trunk line of the Intel switch must be specified to a VLAN one by one. cisco can use a command: set vlan 3 1/1-2 to switch port 1/1-2 from Vlan1 to Vlan 3. on an Intel vswitch device, you must not only delete the Port from Vlan1 and add Vlan 3, 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 8016 devices, VTP protocol is supported on other devices 2026 and 8016, and VLAN1 cannot be configured on, 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 the native vlan command, While Huawei uses the default vlan command.

The Cisco spanning tree is PVST, and each Vlan has its own spanning tree. Huawei is a standard single spanning tree (the same as an Intel switch), but now we have introduced the Spanning Tree (SPT Domain) to solve the problem that the Spanning Tree is too big to expand. Currently, Intel vswitches for each model can support the uplink ports of 1000BASET, and 470,480 supports multiple 1000BASET ports.

In terms of Optical Fiber Connection distance, Intel vswitches are similar to Cisco switches, but there are some problems with rate auto-negotiation. For example, when a 480 m optical fiber port is connected to a 460 m optical fiber port, automatic negotiation should be disabled. Similar to Huawei devices, when a 8016 m optical fiber port is connected to a 6506 m optical fiber port, automatic negotiation should be turned off. Otherwise, port 8016 may appear and port 6506 may not start, however, the optical power machine has normal optical signals after testing.
