maintains the previously defined features. For terminals moving in different VLANs, the terminals can obtain new VLAN definitions. * Control communication activities A VLAN can consist of the same or different switch ports. The broadcast information is restricted in VLAN. This feature limits that only the ports in the VLAN can have broadcast and multicast communication. Management domain) is a collection of multiple VLANs with only one manager. * Working Group and network security Dividing netw

A large number of expert Advisors are currently circulating in the market , but 99% 's use of the EA does not make them profitable for me. What's the best way to get the EA to make a profit? This article will explain how the expert Advisor is profitable in STP mode, before first stating what an eais. ea ' all called Expert Advisors (Expert Adv

(portfast is typically usedon ports in Access mode)Root guard: The purpose of root protection

STP: Spanning tree Protocol, in order to prevent broadcast storms in a ring-switched network, logically disconnect a backup line, and when there is a problem with a line, the blocked port will automatically open and continue to work.Root bridge: In a switched network there must be a root bridge, which controls the stability of the entire LAN, security, it is very important.pvst+: A VLAN-enabled STP switchin

However, if you select the Java item below SCA, an error message is displayed: the current page contain invalid value .: This is caused by a bug in STP. Solution:You can download the corrected

The smaller the priority value, the higher the priority. 0 is the highest, and 61440 is the lowest. When oneVswitchWhen the root port or blocked port of receives the inferior BPDUs package, it indicates that the indirect link from the switch to the root bridge is faulty, and the link between the switch and the root

Using C # For secondary development of AutoCAD (1) As we all know, the main tools used for secondary development of AutoCAD are ObjectARX, VBA, and vlisp. But their advantages and disadvantages are obvious: ObjectARX has powerful functions and high programming efficiency, but its disadvantage is that programmers must master VC ++, which is very difficult to learn; although VBA and vlisp are simple and eas

STP Definition 1. STP Spanning Tree Protocol) is a layer-2 link management protocol. Its main function is to provide redundant paths in Layer 2 links to ensure reliable and stable network operation on the basis of ensuring that there is no loop in the network. 2. The loop will cause infinite data loops in the loop, and the terminal site will receive duplicate information,VswitchObtain the MAC address of the

One, STP overviewSTP (Spanning tree Protocol, Spanning Tree Protocol) is a ring-proof application that is applied to the switch. function is used for anti-ring.Basic principle:By passing a special protocol message between the switches, the Bridge Protocol Data Unit (BPDU) is adopted to determine the topology of the network. There are two types of bpdus, one of which is configuration BPDUs (configuration BPDUs) and one TC BPDU (topology change BPDUs).T

Build tree initialization and Convergence STP establishes a root node, called the root bridge, and constructs a topology in which each node in the network can arrive at only one path, the final generated tree originated from the root node. redundant links that are not part of the shortest path tree will be blocked because such paths are blocked, therefore, it is possible to implement a non-loop topology. When a data frame is received on the blocked li

STP protocol and working process STP protocol (Spanning Tree Protocol) is a layer-2 management protocol with the standard of 802.1d. IEEE 802.1d is the earliest STPS standard. It provides a dynamic redundancy switching mechanism for the network. The STP protocol can deploy backup lines in the network design and ensure that * the backup line is closed when the mas

CCNA Experiment 13 STP the Load Balancer Environment: Windows XP , GNS3.0.7 Purpose: Learn how to Achieve load balancing in STP Description: The load balancing of STP is actually the use of another blocking link in the loop to share the load in the network steps: Open the GNS to build the project with the following topology:650) this.width=650; "src=" Http://

The implementation analysis of STP in Linux Network Bridge This article turns from: http://blog.sina.com.cn/s/blog_a3eacdb2010158hn.html I. The framework structure of STPSTP sends the BPDU package, which has two types: Configuration and TCN (topology change notification);There are two kinds of processing for BPDU packages: Receive and send (nonsense),For the configuration type of the BPDU packet sent, it is done by the timer, parameter BPDU packet of

I have mentioned in the previous article that if an enterprise only uses one vswitch for networking, there will be a single point of failure. If the switch is broken, then several modules cannot work normally at this time, A client cannot access the server, connect to the internet, or access the printer. In other words, if a fault occurs, the entire network cannot work normally. Therefore, in a general switched network, we all need to perform redundancy on the switch, but introducing redundancy

STP protocol ParsingIntroduction: a switch is also known as a bridge. In a bridge LAN, a redundant path is usually established to enhance the reliability. The network segment is connected by a redundant bridge. However, because the bridge does not isolate broadcast, the bridge loop is fatal to a LAN.Description of the STP Protocol www.2cto.com STP-Spanning Tree P

1. BPDU Message FormatThe switches use BPDUs (Bridge Protocol data units) to Exchange STP (Spanning Tree Protocol) information, and the BPDU messages are divided into two scenarios (STP working at the data Link layer) that are two classes of configuration BPDUs and TCN BPDUs respectively. BPDU Frame Frame Header Data (BPDU message) Fcs Configure BPDUs (con

as we all know, the main tools used to develop AutoCAD for two times are: Objectarx,vba,vlisp. But their advantages and disadvantages are obvious: Objectarx powerful, high programming efficiency, but its disadvantage is that programmers must master VC + +, and the language is very difficult to learn; VBA and Vlisp are easy to get started with, but they seem powerless to develop large programs. Is there a language that can combine their merits and try

floors are interconnected with the core, which is environmentally friendly with MDF switches. IDF also has one UTP to MDF for backup.When a fault occurs, green means that all workstations connected to MDF are correct, but red means that all workstations connected to IDF cannot connect to the server. Based on the previous line rectification, it is determined that the floor backbone is interrupted between MDF and IDF. However, because the LAN has become environmentally friendly,
