Managing the vswitch configuration file is still very important for users, but many users still do not pay much attention to it. This is very dangerous and their networks will also have security risks. The configuration file is the core of Cisco network devices. The configuration file is like the Registry file of the operating system. If the registry is damaged or the configuration is inaccurate, the operating system cannot be started or run stably. If the vswitch is used. If an error occurs in

There are many things worth learning about Ethernet switches. Here we mainly introduce the Ethernet switch purchasing techniques and principles. Currently, Ethernet switches use three packet exchange modes: pass-through, storage-forward, and fragment isolation when transmitting data packets from the source and destination ports. 1. pass-through switching An Ethernet switch using a pass-through switching mod

The most widely used switch for small and medium-sized enterprises is the 24-port Gigabit Switch. Therefore, when purchasing a switch, you must make full consideration. A clear purpose is to save costs for everyone. In network equipment, switches may be the most familiar devices of network administrators, especially access layer switches. However, when purchasing

bring great benefits to the future expansion of the network. VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with routing functions are widely used in VLAN networks of large and medium-sized enterprises. However, we must be clear that a VLAN network using a layer-3 Switch also requi

The switch in Java jre7 and later versions supports the implementation details of String, jre7switchThe switch in Java 7 supports String implementation details. Author: zsxwing updated: 21:08:02 release: 13:58:19 Before Java 7, the switch can only support byte, short, char, int, corresponding encapsulation class, and Enum type. In Java 7, String support that has

GE backbone switches are commonly used. So I have studied the performance test report of GE backbone switches. I will share the report here, hoping to help you. Several Gigabit backbone switches provided for test are provided with detailed documentation. Here we first introduced the instructions of Digital China D-Link, which is very detailed. The previous section describes the basic knowledge of layer-2 switching and layer-3 routing, and then describes the functions of vswitches in detail. In a

Therefore, the use of VLAN in the initial design of the network can bring great benefits to the future expansion of the network.VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with routing functions are widely used in VLAN networks of large and medium-sized enterprises. However, we must be clear that a VLAN network u

The fundamental difference between switch...case and If...else is that switch...case generates a jump table to indicate the address of the actual case branch, and the index number of the jump table is equal to the value of the switch variable. Thus, Switch...case does not need to traverse the conditional branch as If..

Friends, have you ever been in a situation where your network is slowly pausing, yet all switch ports are sending data continuously. You must have a feeling that the network Computer workException, and may even have suffered an attack. What are you going to do about it? The author believes that the first step requires you to open the Network Protocol analyzer and capture the data sent from the core router. From the Protocol analyzer, you can see tha

There are many things worth learning about the switch system. Here we mainly introduce how to reasonably configure the switch so that the switch system can control the network at will. With the rapid development of information technology, many organizations have established their own internal networks to cater to the information development trend, in the daily of

The configuration of network management switch has always been fascinated by many people, not only for the general users, but also for many professional users, but also as an important and basic indicator of the level of network management. this is mainly in two reasons, one is the vast majority of enterprises configured switches are desktop non-network management switch, do not need any configuration, is

Tags: Cisco switchBasic configuration and management of switches• Technical Principles• The switch is managed in two basic ways: in-band management and out-of-band management.• The console port management switch through the switch is out-of-band management, which does not occupy the network port of the switch, and the

The Cisco layer-3 switch is another core switch developed by Cisco. It aggregates the bandwidth of the backboard of the switch that is stacked together, in this way, the total backplane of the switch stack is the sum of the bandwidth of several stack switches. Note that not only the ports used are different, but the ca

The most important function of a vswitch is to speed up the fast data forwarding in a large local area network. The routing function is also used for this purpose, so the switch port issue is also very important, it is really not easy to set a vswitch port. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traff

What is a LAN switch? Is Traditional encapsulated storage (EMC/HDS) to be replaced by I-Swith smart switch Cisco? Based on these questions, let's talk about our own views and opinions. I hope you can study them. As the fault location is located, it is easy to solve the fault. A friend estimates that all the signal lights of the faulty switch are flashing constant

Vlan configuration ideas: access, Trunk) 1) create a Vlan Configure static VLAN on an IOS-based switch: Switch # vlan database Switch (vlan) # vlan-num name vlan-name Switch (vlan) # exit Switch # configure teriminal

Earlier Ethernet switches used the architecture of Gigabit Ethernet switches, but added the 10GE module to support 10 Gbit/s Ethernet. We once made a 10G Ethernet topic named "10g power" in a newspaper in October 13. Many manufacturers mentioned that the early 10G Ethernet products only reached half of the throughput specified in the standard, and some of them produced large latency. What is the current 10G Ethernet switch? The Hong Kong Bay network c
