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

The comparison between a layer-3 Switch and a router is in a large LAN. This function is perfect and helpful for understanding the layer-3 Switch. However, some manufacturers' switches can also directly connect to the Internet to

when he cannot find the address, and the hub is only responsible for forwarding the email regardless of the Bounce Message. Vro A Router operates at the network layer, the third layer in the OSI Layer-7 network model. It works by removing the information of the second layer (data link

This article briefly introduces the composition of a layer-3 Switching Network and the responsibilities of each layer. Cisco layer-3 switch is a typical

of using Server Load balancer to improve the scalability, availability, and manageability of Server clusters. This chapter mainly discusses the deployment of Server Load balancer and several solutions for deploying Server Load balancer in the existing network. We will also discuss how to design highly available solutions to implement fault tolerance for different network components throughout the network, including Load balancer. Before discussing the network structure, we need to understa

Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidth. Three-tier competition

Experts tell you what a layer-3 switch is. Now every household has their own computer and understands what a layer-3 switch is. At that time, the layer-

know that in order to cope with the increasing data traffic, shared media networks have been replaced by switching networks.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

, as the core of the network, there is no substantial breakthrough in the router technology that acts as the interconnection between networks. Therefore, a new routing technology came into being-layer-3 switching technology, which is a routing technology because it works on the layer-3 network protocol, the two-

/100 Mpbs adaptive ports and 1 Gigabit expansion slot. You can purchase different types of Gigabit modules provided by youkang to achieve the function of connecting to a gigabit network. The UGS-7324RS has 15 Gbps non-blocking back-board bandwidth, in the layer-2 switch, the packet forwarding rate reaches the line speed value of Fast Ethernet; As a layer-

of G.703-ETH bridge converter for access, the price is equivalent to G/V converter, therefore, with the new network access solution, the larger the scale, the more nodes that are connected to the downlink, the more cost savings. When the center end of the uplink uses a layer-3 Switch for access, the downlink branch node does not need any grade router, only need

There are many things worth learning about security switches. Here we mainly introduce the meanings and new functions of the layer-3 security switch. Security Switch-the new darling of the network industry, the gatekeeper of the network entry, is aiming to raise a large knife to all insecure factors. With the advent of
