cisco core layer switches

of network resources. the application layer switch is placed on the core layer or aggregation layer instead of close to the lower layer intervention layer, this allows network managers to allocate network resources at a lower cos

configuration, the MAC address can be acquired to the specified IP every time, and only the specified IP address can be networked. Configuring IP-MAC bindings on layer three switches is relatively complex to configure and maintain. In fact, there is a way to enable DHCP on the gateway to each VLAN. Ip-mac bindings are made directly on the gateway. Please continue reading:2. Three

The 10-ge core switch is still quite common. So I studied the perfect design concept of the 10-ge core switch and shared it with you here. I hope it will be useful to you. Quidway S8500 series 10-Gigabit core switches are a new generation of high-performance 10-Gigabit core

reliability, such as the layer-2 Spanning Tree mechanism, supporting 802.1W and 802.1 S, this enables faster and more efficient convergence, and implements a layer-2 structure of global load balancing. In Port redundancy, 802.3ad is supported to achieve load balancing between multiple physical ports, redundant backup mechanism for each other; supports VRRP-standard routing redundancy protocol on the third

Mainstream layer-3 switches support security level and virtual subnet division. Today we will mainly explain some comprehensive applications of layer-3 switches in TMIS networks. With the rapid development of China's economy, the transportation volume of Railways has increased significantly, requiring the transition fr

The Group was originally connected to a subsidiary using the SDH leased line of China Telecom, and now a new mobile leased line is added, which is actually a transparent link. The core switch of the group is cisco00009, and the core switch of the subsidiary is Huawei 3526, all of which are three layers. Therefore, the two cores are connected through routes.You can perform the following two steps:1. Find an

network transmission channel. Because the LAN contains a large number of computers and relies solely on anti-virus software to scan and kill one by one, the workload is huge and it is not conducive to efficiently solving network faults, therefore, I plan to test whether the communication speed between computers in the LAN is normal. I first pinged the IP address of one of the computers, and found that the ping command responded quickly. However, I was a little worried, as a result, I tried to s

, the lack of advanced control over network frames is not intelligent and secure, nor can it support switching ports with different rates; in contrast, the "Storage and forwarding" switch mode checks and controls the reading of network frames. Lenovo network products all adopt the "Storage forwarding" exchange method. Correct Interpretation and test of vswitch Port Summarize the market status of high-end Switches Resolve

Layer-3 route switches are still commonly used, so I have studied the solutions to soft faults in layer-3 route switches. I will share them with you here, hoping to help you. Two days ago, our company's network was upgraded, and the core device adopted the Intel550 series L3

control can be implemented at multiple layers of the network. For example, in a TCP/IP network environment, you can use the ICMP protocol to suppress the source on the Layer 3, that is, the network layer to implement traffic control. This mechanism is established between two sites on the point-to-point link. If the receiving site is congested, it can send a frame called a "paused frame" back to the Origin

Faults of a core switch are hard to be listed here. The best solution is to do a good job of daily protection, keep relevant logs, and provide a suitable working environment for the switch, in this way, the core switch can work normally. No matter how good the performance of a core switch device is, there will be potential faults. Just like a human, no matter how

With the development of China's exchange industry, various switches have been updated and upgraded. Here we analyze the comprehensive performance and Practical Application of Huawei's 10G core route switch, quidway S8500 series 10-Gigabit core route switch (S8500) is a new generation of high-performance core route swit

With the development of China's exchange industry, it also promotes the wide application of high-end core switches. After years of development, redundancy has become one of the mainstream design methods. At present, many industry users use a single device design for their network core and aggregation layer, such as a s
