Remove the first row of the switch can continue to use the Internet? The said a little don't understand, you pull the switch, will take the following each screening good ah,CodePudding user response:
Possible reasons are:1. The switch has a loop,
2. The switches on a device in the virus, timing outbreak of cyber attacks, lead to slow,
You can install a network monitoring software, look at the flow of what is normal, such as WFilter, there is also a "network health detection plug-in", can detect the arp deception, network loop network problems, such as,

You that pull the switch running light is what the state of the state to look at the first light is a what state, if it is a flash, most of the time a cable that two heads are inserted in the switch on, if it is a single port lights flash, that means the corresponding data block the port terminal, it is ok to inspect the terminalCodePudding user response:
Each segment is the limit of speed, you take this 100 m points to see, I feel, this time in the afternoon, where did you squeeze on the switch, switch performance is bad, and is not uniform distribution load, loop, should can't,CodePudding user response:
Several methods for reference,1, since there is only one found a switch, the further step, the partial time switch on the terminal access, if received a terminal, network found abnormal, focus on trying to identify the terminal, (have the interval between batches)
2, network ARP monitoring software to check whether there are abnormal flow IP,
3, if they are managed switches, landing port utilization, high shielding of the port, the terminal,
4, replace the switch,
