Hurry, hurry! Switch problem, switch problem! 100 points! Come on

The broadband network cable of the telecom is directly connected to the switch (if it is ADSL, it is also the same to connect the modem to the switch), and the host IP setting method for dial-up Internet access first: see the local connection in the network connection, click on the right health selection properties, and click the Internet Protocol (ICP IP) attribute before the icon in the notification area after the connection, and click to use the following IP address: IP address to fill in:

Subnet Mask:, Default Gateway:, Preferred DNS Server:

Point OK. Then establish an ADSL connection on this machine, and then click on the ADSL connection to select the attribute Advanced: will allow other network users to connect through the Internet connection of this computer.

Other machines also use the right health point local connection attribute in the network connection, except for the first IP address to fill in: the latter number is filled in except 1 2 255 which number is OK), the rest is the same as the first machine.

In this way, the first to establish a connection enters the account password to connect to the Internet, and after dialing in to connect, the other machines will naturally connect.

Other machines can also be the host, other machines to be the host also establish the same dial-up account and password on the line, in fact, there is no need to set up each one like this, with one or two management personnel with the machine to set up this way, just say that this method can work, in addition to these connected computers in the LAN are set up with a solid IP, but also easy to manage).

This method only uses a switch instead of a router to share the Internet, does not use a server, and only needs a network card on the host used for dial-up, and there is no need to add another network card or anything, which is simple and convenient.

Yes, both of your computers are set to dial-up, and whichever one is turned on first will use to dial-up the Internet.

Model should support two computers to dial at the same time, you can build an adsl to try, if it doesn't work There are two ways: one, buy a router, two, buy a network card, and access the Internet through sharing.

No, the switch is a network device running on the second layer, which can only recognize the MAC address, and two computers dial at the same time, there will be a preemption situation, and one will not be able to log in to the other.

TP-Link SF1005+ 5-port small home switch, this kind of thing is easy to break, and there are many fakes, borrow a small switch to try it, first eliminate the fault of the network cable crystal head, etc.,

In this case, it is best to find another switch to replace it, because the switch has poor heat dissipation or the power transformer has poor power supply.

Hello, the general switch light flashing wildly is caused by the following situations:

1.There are symptoms of loops, such as network cables, internal short circuits in network modules2Virus data traffic is too large, ARP attack, broadcast packet 3If the hardware failure of the switch is just 9-16 ports as you said, it cannot be repaired by power-off and restart, while 1-8 ports and 17-24 ports are no problem.

Then most likely it is 3Switch hardware failure.

If you want to confirm, unplug all 24 network cables, power off the switch for a few minutes, and then turn on the switch to check and clear all configurations, such as VLANs and ACLs, if possible.

It is common for the internal circuit module or network port module of the switch to be damaged, and Jinlang is not a good brand.

It may be a network cable problem or these ports are configured on them, and the lights are on and off, which should be due to the working state, and the privileged mode sh run to see what the situation is.

Let's see if there's something wrong with the network cable. Usually not.

Based on the description of the landlord, I gave the landlord a requirement for the switch: first, it is simple and easy to use, not too complicated; Secondly, because you have some IP** and AP equipment, it is recommended to consider switches with PoE functions, which simplifies deployment and saves power, and should have capabilities such as QoS to ensure that the bandwidth and resources of IP voice are sufficient; Third, it needs to have its own characteristics in terms of security, such as supporting VLAN, port authentication, etc.; Fourth, the landlord unit should not be of the IT type, so it is necessary to focus on the services attached to the product.

What to say about the Cisco 300 series manageable switches, I personally think that the following aspects are incomparable to other homes.

First, it is very competitive, you can rest assured, it is definitely cheaper than HP and 3com;

Second, the 300 series switches definitely surpass other competitors in terms of the number of gigabit ports and poE ports, supporting up to 52 gigabit ports, while the others are estimated to be more than 40, right? On the PoE port, 300 is up to 48 100 Gigabit PoE ports, I believe that your enterprise will be able to connect more PoE devices in the future!

Thirdly, the 300 series all have built-in QoS intelligence, which can definitely support your voice applications;

Fourth, in terms of simplicity and ease of use, I personally think that the 300 series has done a very good job - based on the web interface for configuration, and also supports SNMP remote configuration;

In terms of security, I have the impression that the 300 series supports three-layer switching, supports VLAN establishment and inter-VLAN data**, this function seems to be not available in other products of the same grade, and it also supports guest VLAN, which can realize the requirements you said for visitors, of course, it also supports port authentication and ACL and other functions, in short, it is very comprehensive;

First, the switch Chinese meaning, role advantages disadvantages.

1. Basic configuration console -- is to use the console line to log in to configure.

2. Telnet configuration --- remote telnet login, you need to enable this function.

3. Layer 2 VLAN: - Layer 2 virtual network.

4. Layer 3 inter-VLAN routing--- communication between VLANs through routing.

5. The --- of single-arm routing VLAN is similar to that of Layer 3 inter-VLAN routing, that is, a router is used to realize the communication between various VLANs.

6. RSTP --- fast spanning tree protocol, which is used to prevent Layer 2 loops.

7. Port aggregation --- is mainly used for connection between switches. If there are multiple redundant links between two switches, STP shuts down several of the links and keeps only one of them, so as to avoid Layer 2 loops. However, the advantage of path redundancy is lost, as the link switching of STP will be slow, around 50s.

If you use an Ethernet channel, the switch will unite a group of physical ports as a logical channel, that is, a channel group, so that the switch will consider the logical channel to be a port.

Second, the router.

1. The basic configuration of the console --- the same as above.

2. Configure telnet --- as above.

3. Static route configuration--- Configure static route, which is the source address mask and destination network segment mask.

4. RIP route configuration --- the simplest dynamic route, with version 1 and version 2

Buy a few for your own experiments, it's not expensive now.

After two years of working in a company that sells machines, I understand that optics are useless.

These are all moves, the important thing is the internal force, and it is good to integrate it.

Circles have to be built on their own.

First of all, routers do not occupy each other's bandwidth when surfing the Internet, for example, if you have 1m of bandwidth, then if one person accounts for 600k, then the other three people can only occupy a total of 400k, that is, although the routers occupy each other's bandwidth, they are allocated on demand, which will also affect the network speed.

Secondly, the router Internet is the same as the switch Internet access, because the router is more than the switch is the routing function, if you turn off the routing function, then it is a switch, and it is also working as a switch while it works as a router.

I don't know if you understand this, good luck.

Whether you use a switch or a router to share the Internet, your network speed will be divided equally, and if there is no route, your network speed will not be equalized. Just use the route to use the average network speed of several of your computers, if you use the setting computer host (that is, ** server) to surf the Internet, the network speed of the host and other auxiliary machines is not the same.

To correct your understanding of routing, in fact, whether it is a switch or a router, the common higher-level network resources are shared. Other words. Even if you use a router in your dormitory, when you connect to the campus network or the extranet, all computers in your dormitory that access this route will share this bandwidth.

As for the function of the router, it is much more advanced than the switch. If the switch is a bicycle, then an ordinary home router can be considered a motorcycle. The function of the router is mainly reflected in the fact that it can provide various network management for administrators.

At the same time, routers can provide DHCP services, which is why there is no need to go through the hassle of LAN setup with routing.

Your understanding was wrong before. Bandwidth increases with the number of Internet connections, regardless of the switch or router. The reason why you use a switch environment, your host is set up to share the Internet, and you feel slow, because your host is processing other people's network requests, if you use a router instead, then these processes are all handled by the router, and you feel that the computer is just as fast.

By the way, the performance of the Intenet shared connection that comes with Windows is really poor. There is no professional shareware, or router hardware to deal with

Almost good router porphyry.

If there are three people on it, the Internet speed is good, buy a good router, it will be better, broadband occupation, you don't need anything. Half of the broadband fee is paid for each person.

If you use a switch, you can share, but the router cannot, and the Internet speed of the router will be divided equally between you! The switch is copied to everyone on you, and the speed of Internet access is the speed that is pulled back.

These are fixed and there is nothing to bargain about.

You already have so much bandwidth, and if you want to do it without occupying each other, you can only limit their bandwidth through the router!
