What’s so strange about that?
The DHCP server has a short reservation time set (eg in mikrotik is 10 minutes). The system must renew the IP address according to the information from the DHCP server
we check cable length and connection with switch port ,
speed set to 100Mbps and half duplex , and observe this issue not reported.
still waiting for our team to replace cable and then check with speed 1000Gb : Full Duplex.
update shortly.
