When connecting a computer to a switch, it may take 30 seconds or more for the computer to communicate with the network. If you are in a hurry to use, 30 seconds of waiting is enough to make you feel very long. Let's see how we can speed up the port initialization process for the switch.
Understanding the process of switch port initialization
When you connect a
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
In order to help enterprise users better understand the meaning of layer-3 Switch, understand the various new technologies supported by the leading layer-3 switch in the current market, and their position and role in the next-generation smart enterprise network, the computer world evaluation lab recently organized a deep technical test on layer-3 switches.
An in-depth analysis of layer-3 Exchange Technology
Layer-3 switches are quite common, so I have studied the comprehensive description of layer-3 switch technology. Here I will share it with you and hope it will be useful to you. The emergence of layer-3 switching technology solves the problem that the subnet must be managed by routers after the network segments are divided in the LAN, and solves the network bottleneck caused by the low speed and complexity of traditional routers.
A layer-3
In addition to connecting to the same network type, the network management switch can support switching between ports at different speeds to ensure the collaboration between high-speed ports and low-speed ports, the following is a study.
Vswitches are the most important network connectivity devices in Lan. Most LAN management involves vswitch management. However, many campus network administrators are still unfamiliar with
SNMP is widely used. So today we will introduce you to the knowledge of SNMP monitoring switches. So what is the specific role of this SNMP monitoring switch? Using SNMP to monitor switches: it is easy to solve switch faults. in the Internet era, we often encounter troubleshooting methods for SNMP monitoring switches. Next we will introduce the knowledge of SNMP monitoring switches, including how to use SNM
Port security Configuration for the Cisco PT Simulation Experiment (7) switchExperimental Purpose : Master the port security function of the switch, control the user's secure accessExperimental Background : The company network adopts the personal fixed IP Internet program, in order to prevent the company internal User IP address borrowing, using, unauthorized access to the switch and other violations, while
1. Set host name/system name on iOS based switch:
Switch (config) # hostname hostname
To set the hostname/system name on a CLI-based switch:
Switch (enable) set system name name-string
2. Set the login password on the iOS based switch:
Classification and function of switch
The switch is the "cornerstone" of the network platform, also known as the network switch. It is also a kind of hub, but it is quite different from the common hub function. A common hub only acts as a data-receiving transmission, while a switch can intelligently analyze packets an
First, the network environment:
The company uses the 3500 series (Specific model 3548) switch, which is connected with a Huawei 2621 router on the switch, through the telecommunications of fiber-optic internet. Because you forgot your password, you are trying to break its password.
Second, the preparatory work:
Because the entire work needs to break the network, after all involves restarting the
With the continuous warming of the wireless wave, more and more institutions, enterprises began to implement wireless local area network. Up to now, wireless LANs are typically made up of clients connected to access points, while access points provide security features, management functions, and other intelligence needed to control the wireless portion of the network.
The problem with this is that managing multiple access points is an impossible situation for networks that may involve hundreds
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
How to Use H3C Huawei switches: about port and VLAN technology, this article describes QoS, VLAN technology, and switch port speed limit, port configuration, etc, the author gives a comprehensive introduction to all the relevant knowledge about how to use H3C Huawei switches.
H3C Huawei switch usage system information: this page is mainly used to display and configure some system parameters of the
I. layer-3 switches-use layer-3 switches to implement VLAN division and IP routing between VLANs

In the Internet cafe environment, many netusers use a variety of software: games, QQ, video communication, browsers, during communication, these applications will generate numerous data packets transmitted both in and out of the network. This transmission is based on the broadcast mechanism in the LAN switch en
whether a network loop occurs on the specified communication port. Once the loop monitoring function is enabled on the specified Ethernet communication port, the switch device can automatically and periodically scan and monitor all communication ports to determine whether the communication port has a network loop. If a switch port is monitored as a network loop, the sw

In the Internet cafe environment, many netusers use a variety of software: games, QQ, video communication, browsers, during communication, these applications will generate numerous data packets transmitted both in and out of the network. This transmission is based on the broadcast mechanism in the LAN switch environment, therefore, the spread and collision of broadcasts are inevitable. When many clients, but all of them belong to the sa
What is a wireless switch and a hub? As the main connection device of the local area network, vswitches have many obvious advantages over hubs.
We have learned that the data packet transmission mode of the hub is broadcast. Because only one broadcast exists in the hub, only one data packet can be transmitted at the same time, low channel utilization. For wireless switches.
It can "recognize" every computer connected to itself. Why? It is based on the
With the wide application of Ethernet switches in recent years, and some changes have also taken place in such products, we also hope that these changes will promote their technological development and give users more surprises. With the further construction of information networks in China and the further improvement of network quality, high-speed and high-performance Ethernet switches will become the mainstream of network product development.
