many resources on the Internet for your reference. You can also look at the companies that have done well in this area and learn from them. For example, a recent article describes how Telekom Malaysia adopts the internal and external Method for migrating to IPv6, and IPv6 supporters need to be prepared to persuade the management to understand the advantages of IPv6, these advantages are not very obvious and easy to see. In addition to pointing out IPv6 Security Issues, Neetha Edwin also talked

Practice of setting a route table to restrict Website accessThe website that received this experiment: for short, "website", PING the website domain name and obtain the IP address. The IP address ends with. 69 www.2cto.com. Then, we can find out how many hops the route goes through under tracert.Www.2cto.com uses SolarWinds. Engineers to scan the IP address segment of the website. We know that there is a Cisco router in the website CIDR block, which t

user data packet protocol on port 1900. Within 24 hours, 539 matching modes appear. This indicates that the attacker exists.Because forwarding traffic data is only a feature of some routers and switches, you need to find a way to capture and view the data. You can use VPC analysis tools from companies such as SolarWinds, NetScout, or lanw.cn, or use the aforementioned log management tools. I chose 21 Ct's LYNXeon tool because it not only analyzes the

capacity is taken into account, and iops, latency, throughput, and other factors that affect performance are not fully taken into account. For example, an application requires a capacity of 10 TB and may need to purchase 20 TB or even many other storage to meet performance requirements. A reasonable solution and details should be fully discussed with the storage vendor. For example, what raid is used by the hacker, the number of diskspindle in the array, and what type of storage hard disk is us

information appears continuously on the screen, note that it appears quickly. If it is not occasional, it indicates that there must be a loop. If no debug arp occurs, it can be switched off, then, check the ARP information displayed on the screen. The information will certainly include interfaces. Then, check these interfaces and finally confirm. We recommend that you use the last one. Technical support: 1. If a loop occurs in the access layer, for example, if the HUB is short-circuited, the sw

a response rate of 20%. Study the company you are interviewing. Does it comply with industry regulations? Do they value agility and customer acquisition? Or are they focused on maintaining a small group of high-quality long-term customers? Make these preparations before the interview so that you can answer the questions you want to discuss. 2. If you want to control the data center, let's talk about change management. The change Administrator provides a single administrator with a way to contr

The transmission monitoring system includes FactFinder of BlueStripe, ApplicationManager of ManageEngine, Web Application Monitor of SolarWinds and related components, as well as cloud computing-based platforms such as Boundary and Monitis. A cloud management stack (such

needs. Pay attention to whether the stack link can achieve full duplex, stacking unit and uplink redundancy, and whether there is a single fault point. The star stack structure usually has a single fault point. Network traffic statistics and monitoring capabilities Network traffic statistics and monitoring capabilities are an important feature of edge stack switches. There are many ways to implement traffic management, from simple SNMP, RMON to complex RMONII, Netflow, and

current vswitch, or using a new hardware module to insert it into the existing system, so as to enhance the forwarding performance of IPv4/IPv6; or a brand-new IPv6 10-ge switch. Security and Traffic Management Security and network traffic management are currently the most important topics for users. As a backbone device, you not only need to consider the security of the device itself, but also provide user prevention. That is to say, you must be immune and provide powerful blocking measures to

As an inbound or outbound QoS site, edge switches play a very important role, especially in small and medium enterprises, if the edge devices of the network integrate QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3, therefore, the end-to-end smart network can be carried out on a large scale, so that the entire network not only has global

In addition to connecting to the same type of network, edge switches can also interconnect different types of networks, such as Ethernet and Fast Ethernet. I hope this article will help you. With the development of the communication industry, people have higher requirements for intelligence. As a representative of smart exchange devices, edge switches are gradually increasing in market demand. If the edge devices of the network integrate QoS, rate limit, ACL, PBR, and
