Basic information of the network The network topology is: The central switch uses Cisco Catalyst 4006-s3,supervisor Engine III G engine in the 1th slot, for three-layer exchange, 1 24-Port 1000base-t module in the 2nd slot, for connecting to the network server; The 1 Block 6 Port 1000base-x module is located in the 3rd slot for connecting 6 backbone switches. One switch uses Cisco Catalyst 3550-24-emi and

LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series 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, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch can provide exchange access to workstations, servers, network segments

Follow the performance competitions of several Cisco smart switches. Many companies now have their own switches to learn about the performance of Cisco smart switches and provide objective references for your selection, select a Cisco smart switch that suits your company. Cisco is the only company in the enterprise, service provider, and commercial SMB that provides a comprehensive range of LAN switching solutions for all core and edge branches in the customer field. Cisco is the only company th

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,

network architecture and firewall deploymentI. network architecture and firewall deploymentThe network structure of the organization is shown in Figure 1. To ensure the stability and redundancy of important devices, the core layer switch uses two ipv9-e switches to connect through the Trunk line. Multiple Cisco 2960 switches are used in the access layer of the office area. The figure below shows only two switches for simplicity. On the core layer swi

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

If we want to communicate between VLANs, we usually use the three layer switch or router sub-interface mode. Linux on the VLAN with Cisco switch relay connection, also can realize their communication with each other.Environment: RHEL 5.2 Minimized installation, physical NIC Eth1, trunk port connected as VLAN switch connected to 2960 GIGABITETHERNET0/1. Another physical NIC Eth0 as an upstream port, connecting to other networks.Cisco

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

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

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

: • Traffic and Protocol ACLs or filters • QoS tags and priority levels (control protocols are differentiated by corresponding service levels or DSCP values) • Selectively disable Layer 2 protocols on untrusted ports (for example, disabling DTP on access ports) • Configure the in-band Management port only on the dedicated VLAN • Avoid using VLAN 1 to transmit any data traffic Command example: Catalyst Operating System (CatOS) software Cisco IOS o Sof

How to back up configuration files for Cisco, ruijie, And Juniper Devices For a company of a certain scale, network device configuration file backup is also a task that cannot be ignored, to prevent one day after your network device fails, you can recover in the shortest time, reduces losses for the company. The following describes the backup operations for several devices: I. Specific ideas: 1. Download ftp software and TFTP Software 2. Configure the ftp software user name, password, and config

layer-2 packets, they will be simply discarded without any port security violation. The IP source protection function cannot prevent ARP attacks on the client PC. ARP attacks must be solved by the DAI function. If you want to support the IP source protection function, it must be a 35 series or above switch. 2960 currently, this function is not supported.

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

CISCO has become a leader in the switch industry, so I have studied the comprehensive performance of CISCO switch 2950. I would like to share it with you here, hoping it will be useful to you. Fixed installation of wire speed fast Ethernet desktop CISCO switch 2950, can provide excellent performance and functionality for LAN. These independent, 10/100 adaptive CISCO switches provide enhanced service quality QoS) and multicast management features. All of these are managed by the easy-to-use, Web-

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

Cisco System Inc. 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 cooperation and mergers, Cisco has successfully intervened i
