I will introduce the key technical parameters of the switch to make it easier for users to compare the different products of different manufacturers when choosing the switch. Each parameter affects the performance, functionality, and different integration characteristics of the switch.
1, Forwarding technology: Switch
A tiered switch is a type of switch. According to the design, the switch can be stacked on top of the other. This switch is different from a rack switch and can be placed in a network cabinet or separately. The functionality of a tiered
The author office used a common two-layer switch, has been silent for us for several years, so far there has been no accident. However, recently, the author of the local area network computer room has a switch suddenly strange phenomenon; taking into account the particularity of the fault phenomenon, the author used a special method to exclude, now the specific troubleshooting process is written out, I hope
Switches and routers need to have certain security, that is, to timely configure a reasonable password, then if the password forgotten how to do? I have encountered this time, due to job transfer, the former network administrator left the department, but the switch set up a password, and did not tell me the successor of the network administrator. What do we do? It's too much trouble to send it back to the vendor. So I personally experienced a password
As one of the core devices in the LAN, the performance of the switch directly determines the data transmission performance of the network. However, after a long period of work, the switch will inevitably encounter such or such a fault phenomenon, in order to solve the problem in time, network administrators often take a remote approach to manage the switching system.
However, sometimes, we will encounter t
As the saying goes, the body is the capital of revolution, a person only strong physique can live better, in order to create greater wealth for society. Enterprise network is like a person, only security measures to do in place, the enterprise in all aspects of the operation of a better. In today's information age enterprises, information for the enterprise is undoubtedly the greatest wealth. With the spread of virus and the rampant hackers, enterprise network security protection has been greatl
The core switch is still quite common, so I have studied the displaycpu command details in the switch. Here I will share it with you and hope it will be useful to you. In the LAN operating environment, the working status of core switch equipment is extremely important. It directly affects the efficient and stable operation of LAN networks. When a fault occurs in
I. host MAC and switch port binding:
Switch # config terminal
Switch (config) # int f0/1
Switch (config-if) # switchport mode access
Switch (config-if) # switchport port-security mac-address 2.16.0000.0001
2. Host IP address and switch
Generally, the failure of a vswitch is caused by the time used. As the Working Hours extend and network applications change, the chance of a problem increases greatly.
A switch is an important device in a network. If a problem occurs, it will affect the entire network system. Therefore, we have analyzed the troubleshooting methods for common switch faults. Computers in the LAN are often connected to
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
A switch is an important device in a network. If a problem occurs, it will affect the entire network system. Therefore, we have analyzed the troubleshooting methods for common switch faults. Computers in the LAN are often connected to switch devices and exchange and process data through these devices, the working status of a vswitch has a direct impact on the ove
LAN switch is still more commonly used, so I studied the local area network switch basic technical indicators, here take out and share with you, hope for everyone useful. LAN Switch Basic technical indicators are more, these technical indicators reflect the technical performance and function of the LAN switch, is the u
Note: Each interface supports only one policy, and one policy can be used for multiple interfaces. Therefore, the download rate limit for the network segment under the port should be defined in the same policy
1. Start QoS on the switch
Switch (config) #mls QoS//Start QoS on the switch
2. Define Access Control List
Switch
First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An important difference between the two is the low-end switch. Each physical port is a logical port, while the high-end switch binds multiple physical ports into one logical port for configuration. In a cisco Network, the switch
Two-layer switchThe development of the two-layer switching technology is quite mature, the two-layer switch is a data link layer device, which can identify the MAC address information in the packet, forward according to the MAC address, and record the MAC address and the corresponding port in one of the address tables within oneself.The specific work flow is as follows:1 when the switch receives a packet fr
Overview:
Currently there are seven kinds of network card binding mode (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6
There are three kinds of commonly used:
Mode=0: Balance load mode, there is automatic backup, but need "Switch" support and settings.
Mode=1: Automatic standby mode, if one line is disconnected, the other lines will be automatically prepared for assistance.
MODE=6: Balanced load mode, there is automatic backup, do not need to "
A netizen does not know the cat and the router, the hub, the switch difference between them what is different? Computer knowledge Network for everyone to answer:
A cat has at least two ports: one to the telephone line and one to the RJ-45 port (network cable)
Routers are generally one port: RJ-45 but one to connect the network, a LAN
A router and a cat are not the same device
Routers, simple is composed of LAN, and also provide including packet fi
Switch type (rack style, fixed-profile with/without expansion slots The rack switch is a slot-type switch that is scalable and supports different network types, such as Ethernet, Fast Ethernet, Gigabit Ethernet, ATM, Token Ring, and FDDI, but the price is more expensive. A fixed-profile band-slot switch is a
