letter, but I don't have enough scrubs. I knew it was not a warrior, and it was not a precursor, so I had so many scrubs and memories. I still remember that a student came to buy my books and put the money out of his pocket in my hand before March 13, year 34. This temperature marks my heart, and when I want to write text, I am afraid that this kind of young people will be poisoned. I am afraid I may not h

, we will see how to use the Catalyst function to meet these needs! Detects suspicious traffic Cat6500 and Catalyst 4500 (Sup IV, Sup V and Sup V-10 GE). It provides a hardware-based Netflow function to collect traffic information flowing through the network. The information collection and statistics are completed through the hardware ASCI, so there is no impact on the system performance. The

Article title: ATICatalyst has been updated to 8.10. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. AMD has updated the ATI Catalyst display driver for Linux to version 8.10. The new version introduces the amdtm cal (Computer Abstraction action Layer) runtime library and Red Hat Enterprise Linux 4.7 support, and

At present, the modular multi-layer switch is widely used. Many people may not understand the comprehensive explanation of the modular multi-layer switch. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. Cisco Systems, the world's leading network equipment vendor, recently announced the launch of a series of new multigigabit Network Security Services. The service is integrated into the Modular, multi-layer swi

efficiency and security, and limits the flexibility of the network to a large extent. If you need to separate a broadcast domain, then you need to purchase another switch and re-wiring it manually. Therefore, virtual network VLAN must be configured.In a large enterprise, its subordinates have multiple level 2 units. When the isolated networks of each unit are interconnected, to manage, secure, and operate the entire network in different functional departments, we divide VLAN.Step 1 subnet Analy

packets between subnets, use standard routing protocols such as OSPF, RIP, VPN, and IS-IS to make route selection. It also provides traffic statistics for ease of management.MLS consists of three parts:Multilayer Switching-Switching Engine (MLS-SE): Catalyst 5000 series switchWith the NFFC or nffc ii.Multilayer Switching-Route Processor (MLS-RP): The MLS-RP provides CiscoIOS-based multiprotocol routing, network services, and central configurationAnd

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 common 10/100 BaseTx Cisco switches, such as C2912 and C2924, some are with Optical Fiber interfaces, such as C2924C with two 100 BaseFx ports, and some are modular, for example, C 2924 M has two expansion slots. The expansion s

Such a person will help the team shape and unite, maintain the health and productivity of the team, and thus contribute to the project. Even if "Catalyst" does nothing (in fact, they usually do many o

point1. Cannot be modified after creation: Spark emphasizes immutability, and in most scenarios tends to create new objects instead of modifying old objects. 2. By viewing data manipulation records, you can efficiently recalculate lost data. 3. Support for the operation of distributed data. Both 4.DataFrame and RDD can be created from the following data sources: (1) A Python dataset for distributed storage. (2) Dataframe or other spark datasets in pandas. (3) files in HDFs or other file syste

A. About stacking technology: How does the 1.Catalyst 3500XL/2900XL stack be implemented? A. Special tiered cabling is required, 1 m long or 50 cm long (cab-gs-1m or cab-gs-50cm) and a dedicated gigabit stacked card Gigastack GBIC (WS-X3500-XL) (which already contains cab-gs-50cm stacked cables). B. There are 2 stacking methods available: Daisy Chain (providing 1G of bandwidth) or point-to-point method (2G bandwidth available). C. 2 ways to do back

It's classic. I use it.DeploymentsThe deployments in this document were implemented in an isolated lab environment. the deployments were cleared by issuing the write erase command on the routers, and the clear config all command on the switches to ensure that all devices have a default configuration. make sure you understand the potential impact of any configuration or command on your network before using it.Catalyst 6500 SwitchNote: The following screen captures show the commands that were ente
