8 out of 16 ports are disabled. From what can be?

Question

network hardware

Hello

, in the office there is a Ubiquiti 16-150W switch,
all ports are used, only every minute the top row of ports is turned off, then after a while it starts working again and so on endlessly.
The people though approximately from what it can be? Is this a marriage or did I set it up wrong?

thanks in advance

Answer 1

normally, ports can be disabled in cases provided by the specifications/protocols supported by the switch. this is usually:
- protection against dhcp/ip/mac spoofing;
- loopback detection;
- commands to administrative down via management protocols (snmp/telnet/ssh/something else).
so I suggest first of all to make sure that the specified features are disabled for these ports and there are no loops in the network.

Answer 2

Switch ports POE? If yes, check the power overload and whether the wires are damaged
