In the network can sometimes appear this kind of circumstance: part of the network, as is caused by a computer, the computer caused by its TPLINK tl - sf1005 + switch all the computer can't get to the Internet, can penetrate many layers of tl - sf1005 + switch, end to the other type switch, if the exception computer directly to the SF1008 + switch, can only lead to six other computers on the switch can't surf the Internet! Doesn't affect the switch of the computer, at the next higher level if abnormal computer received smart switches (such as H3C S3100), the effect is less than other computers, in SF1005 + can't catch any package, if the power will be affected by the switch to restart, can be normal for a few seconds, if pull out abnormal computer cable, network back to normal immediately,

The phenomenon to appear from time to time, sometimes abnormal state of computer is crashed, sometimes no crashes, it affects only 5 to 8 opening fool switches, for smart switch, such as H3C S3100 without any influence, this is how to return a responsibility excuse me everybody, I have determined not ARP attack,

CodePudding user response:

Can only fools and switch from the difference of features; Mainly on the characteristics of the port security,
Such as intelligent switch control loop, prevent DHCP deception, MAC address binding, etc.,

CodePudding user response:

Intelligent switch without any setting, when ordinary switches use! Failure after the restart the computer, the network is normal, no physical loop,
The strange thing is: can affect many layers of TL - SF1005 + switch, but can only influence a layer of TL + or - SF1008 H3C S1008A switches, eight switches a layer is not affected.
I met many times this kind of problem, didn't understand is how to return a responsibility, also hold the bag in the switch,

CodePudding user response:

Also can rule out step by step, the first computer heavy do system, no, directly to switch; No, in Ethernet card

CodePudding user response:

This problem is not met, do mirror port and then caught analysis results? , redo system or tried in Ethernet card?

CodePudding user response:

I've put the company's network again, because I installed the DHCP server on your computer, and address the and company provids the same network segment, the company of people can't get to the Internet,,, because they were from my computer for IP, and then my computer that is the question
