Cisco has become a leader in the communication industry, and its product performance is still very good. Here we mainly explain the common problems and solutions of Cisco switches. Here we will share with you some of them, I hope it will be useful to you. Cisco switch FAQ 1: What switches Does Cisco currently support layer-3 switching? Answer: Catalyst 2948G-L3, Catalyst 4908G-L3,

connect Cisco Catalyst 3524 to an existing network connected by a vswitch. The primary switch is an ipvst00009, and its GBIC is already connected to the ipvst4006 switch. I decided to use port 3 of the Catalyst 6509 module and connect the Fast Ethernet port using a 5-way adapter cable, that is, port 6509 of the Catalyst 3/15 and port 3524 of the

process of a vswitch is complex, and the specific configuration method varies depending on different brands and vswitches of different generations. This article only teaches you the general configuration method, with these general configuration methods, we will be able to link them together.You can configure a vswitch in two ways: local configuration and remote network configuration, however, note that the latter configuration method is only available after the previous configuration is success

Metro is a backbone of ATM, with local authorities as the center, with four backbone nodes: Hankou line branch, Hanyang line branch, Wuchang line branch, and Qingshan line branch, connect them to a man that covers three towns in Wuhan using the OC3 155Mbps optical fiber trunk. See figure 1. All network devices use Cisco Systems. Among them, the core switch of the ATM uses Lightstream 1010, And the edge device of the ATM uses the Catalyst LAN switch

oxidation gas, so that NOx can directly generate hyperboiling acid and then produce concentrated nitric acid by distillation, it is regarded as a good method for making concentrated nitric acid. A direct method is used to directly synthesize concentrated nitric acid from ammonia and air by oxidation. The key to production is to remove the water generated by the reaction. the reaction has gone through the following five steps: ① the production of nitric oxide ammonia and air are oxidized to nitr

Cisco LAN switches are still commonly used. So I studied the maintenance and configuration problems of Cisco LAN switches. I would like to share them with you here, hoping to help you. Cisco LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's ipvst5000 series Cisco LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FD

know that in order to cope with the increasing data traffic, shared media networks have been replaced by switching networks. This change has a direct impact on the traditional routers used for network segmentation. In view of the large traffic that spans the IP address or IPX subnet, the router has actually become the bottleneck of network transmission. The reason is that traditional routers focus more on multiple media types and transmission speeds. Currently, data buffering and conversion cap

switch through a serial port (except for the first time configuring the switch, most of them are due to a switch failure and cannot be logged on through the network port). This is often the case of 100,000 in a rush. However, the more urgent the system is, the more difficult it is to create a command than to log on to the system, because some system prompts will pop up from time to time (or continuously) on the configuration interface opened by the Super Terminal. At this time, command input wi

Cisco System Inc. identifies Cisco switch models in the network industry. With its IOS (Internet Operating System), Cisco is an absolute leader in the multi-protocol router market. Currently, nearly 80% of routers on the Internet come from Cisco. In fact, Cisco also has a full range of network devices, including hubs, switches, access servers, hardware and software firewalls, and network management software. Cisco pays great attention to the tracking of New Technologies. Through a series of coop

Typically, a network management switch can be configured in two ways: a local configuration and a remote network configuration, but note that the latter configuration method is only available after the previous configuration succeeds, as described below. First, local configuration mode Local Configuration The first thing we h

forwarding performance of the exchange engine. In view of the advantages of modular switches in modern networks. Modular switches are of course the first choice for building networks. The following describes several vswitches from the modular perspective. For your reference. Cisco Catalyst 4000 Series network switches The Catalyst 4000 Series provides powerful fundamental architecture advantages. Relying o

You can configure a vswitch in two ways: local configuration and remote network configuration, however, note that the latter configuration method is only available after the previous configuration is successful.1. Local Configuration For local configuration, we need to first encounter the physical connection mode, and then we need to face the software configuration, in terms of software configuration, let's take the most common Cisco "Catalyst 1900" s

With the help of today's advanced smart enterprise networks, enterprises can effectively deploy e-commerce and other applications, thus realizing the optimized combination of labor and the globalization of business. These powerful networks can connect many remote sites, branch offices, mobile employees, partners and customers to provide services for thousands of users. However, there is still a problem that all networks are increasingly threatened by the increasing number of security risks on En
