LAN communication is completed through the "Hub" of the NIC. Therefore, the health status of the NIC directly affects the performance of the LAN network. This is not the case. When we carefully summarize a lot of lan network faults, we find that

Simple identification of whether the wireless network card supports the BT3 and BT4 methods:    Many brothers do not know their network card chip models, or are unable to determine whether they are supported.The following describes the

This economic crisis has severely hurt large enterprises. In addition to some domestic demand-oriented enterprises, companies have begun to make decisions in the cold winter. During this period, in order to successfully launch the award and reduce

There are seven Nic binding modes:1. mode = 0 round-robin2. mode = 1 active-backup3. mode = 2 load balancing (xor)4. mode = 3 fault-tolerance (broadcast)5. mode = 4 lacp6. mode = 5 transmit load balancing7. mode = 6 adaptive load balancing (1) Round-

1) Down status: the router does not exchange any OSPF messages with any other routers; 2) Init status: the receiver router has received the hello packet from the peer router, however, no route id is found in the hello packet of the Peer router .. In

I believe that all my friends in ubuntu have encountered this problem. When Thunderbird is used, garbled characters will appear in the address book. You can solve this problem by converting its encoding on the terminal first, then import the file.

  Lab Topology   Lab procedure 1: configure the basic address and enable the ISP to run OSPF in the middle so that the PES at both ends can communicate with each other. 2: BGP is built internally and MPLS is used to solve the black hole problem. 3:

The cascade port of Port 1 connects to an eight-gigabit telecom line;Ports 2, 3, 4, and 5 limit the maximum upstream and downstream bandwidth of each interface to 2 MB;The detailed configuration is as follows:Bytes -----------------------------------

  Let's test gre over ipsec. The test topology is as follows:     R2 serves as the internet, R1 and R3 serve as the company's headquarters and branches respectively, and the loopback port is used as the following test network segment R1 lo10 ip: 192.

  RT2 receives the route, saves it to LSDB, calculates the route, and installs the optimal route to the global route table: O * IA 0.0.0.0/0 [110/65] via 10.2.26.2, 00:07:10, Serial0/2 O * IA indicates the three default routes delivered Measurement

Network core considerationsThe term "network" can be applied to multiple fields from LAN to SAN and WAN. All these fields require a network core. Our discussion starts from here.The size of a unit determines the size and capability of the core

Tunnel VPN OSPF-- A combination of three muskeysVPN and OSPF do not seem to have much to do with each other. The former is a technology used for secure connection between a public site to a site or a business trip staff and a company, and the latter

The TCP and UDP protocols of the TCP/IP transport layer are two completely independent software modules, so their respective port numbers are also independent of each other. For example, if TCP has a port 255 and UDP can have a port 255, the two do

Configure logical PortA logical port is relative to a physical port. It refers to a port that can implement data exchange but does not exist physically and needs to be configured. Vrouters generally provide five types of logical ports: Loopback port,
