a very important application, which will prompt the IT team to rethink the Network Design of San Jose headquarters. Network convergence-transmitting data and voice over the same network-will save Cisco's long-term expenditure and serve as a platform for future development. However, in the short term, it will put heavy pressure on a diverse platform that forms the Cisco network infrastructure. Cisco Catalys

Cisco's flagship Switch replaces the new brain with the new IOS software modularization to bridge the "operational gap" between IT talent and network service needs ". On April 9, August 29, Cisco Systems announced the launch of a number of software improvements based on Cisco Internet Operating System IOS. These improved IOS software is mainly used in the Catalys

any time. "-- Dave Rogers, senior IT network manager of American Century Investment "By using Cisco IOS software modularization and high availability features on our Catalyst 6500 switch, we can now use targeted software patches to reduce operating costs while improving network availability. Because we do not need to restart the

Today's recommendation: cisco switch module Ethernet application details, familiar with the following cisco switch module knowledge point, you only need to spend a few minutes to understand the cisco switch Module Settings. There

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the c

limited software upgrades, these switches cannot be expanded. The other type is modular switches, which mainly refer to 4000 or more models. network designers can meet network requirements, select different numbers and models of interface boards, power supply modules, and corresponding software. When choosing a device, many people have a headache for long product models. In fact, Cisco has a rule for product naming. For A Catalyst

What is the Cisco switch module? The advanced traffic management feature in the Cisco switch module simplifies deployment and optimization of large networks, which allows many developers and users to extensively learn and study the principles of the Cisco

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

There are many users who use Cisco switches. When selecting their products, it is a headache to see Cisco switch models. Here we mainly explain how to quickly understand these complex Cisco switch models. The product line of the 2900 series is very long. Some of them are com

the current market, any port with a transmission rate of Mbps is referred to as a cisco Gigabit Switch. For example, most mainstream products currently provide 10/100/100/1000 Mbps adaptive and 10/100 Mbps adaptive ports, Mbps ports are provided to desktop users, and Mbps ports are used for core switching. In fact, there are not many products with a single Mbps

switch with two 100M upstream ports. These switches cannot be extended except for limited software upgrades; The other is a modular switch, mainly refers to 4000 and more models, network designers can according to network requirements, select a number of different models of interface boards, power modules and the corresponding software. When choosing a device, many people have a headache for a long produ

MAC address on the switch. In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance. If you do not have this software

there are many cables on the switch. With the naked eye, it is difficult to accurately identify idle ports at once (if an error is accidentally pulled, the Network may fail). Therefore, we used to log on to the switch, run the following command: 3550 # show inter. At this time, the switch will display the details of each port in sequence, including the port disc

DDoS attacks. VLAN A virtual LAN is an essential security feature of cisco switches. A VLAN can implement a limited broadcast domain on a layer-2 or layer-3 switch. It can divide the network into independent areas and control whether these areas can communicate. A VLAN may span one or more switches. It is independent of their physical locations, and devices communicate with each other in the same network.

Cisco is the main force in the entire vswitch. Its products are doing very well in the market. The following article will detail some of the usage skills and precautions of Cisco switches, in many organizations, the core backbone switches are primarily Cisco. In the process of debugging and maintaining
