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

Some friends who are new to ACL (access control lists) may be unfamiliar with vacl. This article will provide a comprehensive description of the use of vacl on Cisco COs and iOS vswitches.The same as the regular access list, dynamic access list, and self-reverse access list, vacl is a part of the ACL extension application. It defines information traffic based on three layers or more, the corresponding parameters are used for two-layer VLANs. Vacls are mostly used in hardware, and are much faster

{ Code; } } The running time of this Code is O (n2) (you can refer to the above method ). If instance 2 is added to the Return Statement in Example 1, the running time is n + N2, and the O (n2) is the general o representation ). As you can see, the big O notation does not have a plus sign, and all these are ignored. There is no constant and only the number of iterations. Many students with poor math, like me, will be confused when they encounter log numbers such as O (logn). In fact, it is not

= 3932160000 bytes, approximately 3750 MB. Therefore, if you set the size of the Undo space to 703 MB, you can check the change that occurred before 900 seconds, or, for an SQL statement that does not run for more than 900 seconds, it is not likely to encounter the "ORA-01555 snapshot is too old" error. If the size of the Undo space is set to 3750 MB, it can basically be changed before 2400 seconds (the m

Protocol) is a public protocol that can be used either on Cisco devices or on H3C devices. Figure 23 Thermal Backup deployment mode for layer network devices The following is an example of the three-layer switch Cisco 3750, which describes the application of the HSRP protocol in the network device hot backup function. As shown in Figure 2, the network structure diagram is the same as the network structure in "one", except that the network device is

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
