What is a layer-2 switch? The operating skills and operating methods of L2 switches are found on some technical forums and blogs for your reference only. In order to adapt to the challenges brought by the deepening of network applications, the scale and speed of the network are rapidly developing. The speed of the LAN has increased from 10 Mbit/s to 100 Mbit/s, at present, the Gigabit Ethernet technology has been widely used. In terms of network struc

Fast switch troubleshootingNetwork administrators often deal with switches during their work. Because switches are widely used in enterprise networks, from low-end to high-end, they involve almost every level of products, therefore, vswitches are more likely to fail than routers and hardware firewalls. So how can we quickly and accurately locate and eliminate faults? Switch faults can be divided into two ca

The security switch mainly uses the access control list to implement the security function of the packet filtering firewall. It enhances the security protection capability and is the first choice for small and medium-sized enterprises. Vswitches play an important role in the enterprise network, usually the core of the entire network. In the network era where hackers are intruding into the cloud and the virus is raging, the core security

Configuration ideas1. Configure the ETHERNET0/0/20 interface as an observation port (monitoring port ) 2. Configure the ETHERNET0/0/1----ETHERNET0/0/10 interface as a mirrored portConfiguration steps1.

Take the Cisco 2950 vswitch as an example. log on to the vswitch and enter the management password to enter the configuration mode. Then, run the following command: Switch # config Terminal # Enter the Configuration Mode Switch (config) # interface fastethernet 0/1 # Enter the specific port configuration mode Switch (config-If) # switchport port-secruity # Config

The monitoring switch is the transmission device between the Network Camera (IPC) and the hard disk recorder (NVR), and the switch gathers and transmits the monitoring data stream to the NVR, which is the important role of the monitoring network. Security Monitoring Network Camera video streaming bandwidth is large, access to more than a few, real-time and stability requirements higher. In combination with

Mac layer Attack rumor address floodA common two-layer attack or switch attack is a Mac flood, with an intruder using a large number of invalid source MAC addresses, which can cause the switch's cam table to overflow, because the switch cannot find the port corresponding to the destination MAC address in the MAC address table, causing the switch to periodically f

Cisco's VLAN implementations are typically port-centric. The port connected to the node will determine the VLAN on which it resides. There are two ways to assign a port to a VLAN, which is static and dynamic, respectively. The process of forming a static VLAN is the process of assigning a port to a VLAN in a mandatory manner. That is, we first set up the VLAN on the VTP (VLAN trunking Protocol) server, and then assign each port to the corresponding VLAN process. This is the most common method we

The large-scale application of equipment, the cost of a substantial decline in competition more rational, these show that the broadband business has passed the life cycle of the entry period, into the business into a long-term. The user's demand for the broadband network is finally to achieve "three nets in one", that is, data, voice, video business of the three-network unity. In order to be able to guarantee the key business of the user, different levels of users to treat, it is necessary for b

First, network description The PC1 is connected to the Cisco3550 F0/1 and the rate is 100M; CISCO3550 's G0/1 for export. Second, the detailed configuration process Note: This configuration: Improve the reprint of some of the incorrect configuration. Each interface supports only one policy in each direction, and one policy can be used for multiple interfaces. Therefore, the download rate limit for all PCs should be defined in the same policy (in this case, Policy-map User-down), while the d

Master the high-end switch cascade to instantly become a master of the network, previously introduced the relevant knowledge. After the publication of the stack and cascade of switches, we have received a number of emails from many readers to discuss with us about the cascade of switches. So we will introduce some related content about high-end switch cascade. High-end
