What should I do if the switch is not connected to the network and the switch is not connected to th

Please describe the topology and configuration clearly, so that you can't see anything.

Although the switch is a layer 2 device, many large units are VLAN settings for each port of each switch, and the default is not set, at this time, so the devices are in a VLAN, that is to say, they are all in a network segment, and often the equipment under a switch has many network segments, at this time, it is necessary to configure multiple VLANs to distinguish, for example, the computer of VLAN10 and the computer of VLAN20 are accessed under a switch. However, they need to establish a connection through a gateway, which is a router, to communicate with each other.

In your case, there are several situations in which you have sent but not received, indicating that you have not been contacted by the gateway, that is, the router

1.Your unit has helped to define the IP+MAC address.

2.If the VLAN setting of your uplink port is incorrect, it is also possible that your IP segment is not configured correctly.

3.If all the devices under this switch cannot go out, then there may be a problem with the uplink part of this switch, if some of them can go out, then refer to situations 1 and 2

If you want to get an accurate answer, please send us the top image. Otherwise, you can only give you some advice, and you may not be practical when you take it.

Summary. 1.Check whether the switch ports are properly connected; 2.

Check whether the network cable is in good contact and whether the network cable is damaged; 3.Recheck the IP configuration and VLAN configuration of the switch; 4.Check whether the ARP table of the switch is correct. 5.

Check whether the OSPF configuration of the switch is correct and that all related routes are enabled. 6.Check whether the function of the port of the switch is correct, and whether the duplex and speed of the port are the same. 7.Try resetting or refreshing the switch; 8.

Try using a different network device to check if the network environment is normal; 9.Try contacting your network operator to check if the network service they provide is working.

What should I do if there is no network from switch to switch.

Dear for a long time, here for you to find the relevant information.

1.Check whether the switch ports are properly connected; 2.Check whether the network cable is in good contact and whether the network cable is damaged; 3.

Recheck the IP configuration and VLAN configuration of the switch; 4.Check whether the ARP table of the switch is correct. 5.Check whether the OSPF configuration of the switch is correct and that all related routes are enabled. 6.

Check whether the function of the port of the switch is correct, and whether the duplex and speed of the port are the same. 7.Try resetting or refreshing the switch; 8.Try using a different network device to check if the network environment is normal; 9.

Try contacting your network operator to check if the network service they provide is working.

Pro, this is for you to find out.

You take a look at it, I hope it helps you.

Are you still overwhelmed by the solution to not knowing that the computer connected to the switch can't access the Internet? The following is a solution that I have collected for you to not be able to access the Internet on the computer connected to the switch, welcome to read:

The solution to the problem that the computer connected to the switch cannot access the Internet.

Topology] Internet --- routers--- switches, --- PCs

Phenomenon] PC cannot access the Internet.

1) Check to ensure that the network topology is connected correctly and the device indicators are normal.

2) Check whether the computer network parameters are correct, and make sure that the computer is directly connected to the router and can access the Internet: this can eliminate the restriction of the router on the computer's Internet access.

3) Try to log in to the router management interface and check whether the management address of the switch conflicts with the router gateway.

4) Check whether the browser is set up with LAN**, try to ping the gateway and the external domain name, if not, continue to check.

If these are all right, then you can locate the problem at the PC and the switch, which can be located from the following steps:

5) Check whether the PC connection port on the switch can communicate with the router connection port, and exclude the restrictions such as the switch setting port learning code rubber, port and MAC address binding, VLAN (whether the port is in the same VLAN as the router cascade port), ACL settings, etc., if so, if it can communicate, then continue to check.

6) Check whether there is ARP spoofing in the intranet, and do a good job of two-way binding and arguing between the IP and MAC of the computer and router, for specific operations, please refer to: How to judge ARP spoofing?

7) If none of the above is set, the device reset is used as a fool switch, if you can't access the Internet, it is likely that there is a problem with the switch hardware, contact the office or dealer for detection.
