stm32h7 ethernet tcp connection lwip

 /* add the network interface (IPv4/IPv6) with RTOS */
  netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &tcpip_input);

  /* Registers the default network interface */
  netif_set_default(&gnetif);

  if (netif_is_link_up(&gnetif))
  {
    /* When the netif is fully configured this function must be called */
    netif_set_up(&gnetif);
  }
  else
  {
    /* When the netif link is down this function must be called */
    netif_set_down(&gnetif);
  }

  /* Set the link callback function, this function is called on change of link status*/
  netif_set_link_callback(&gnetif, ethernet_link_status_updated);

I am using open source lwip.c and I realized my ethernet connection breaks and reconnects time to time. I was wondering if it is okey or expected behaviour in ethernet connections or it shouldnt be disconnecting at the first place.

Hello @tugbaozcan,

Ethernet connections are generally stable and should not disconnect frequently. To ensure the stability of your connection, please verify that your application performs a periodic check of the link. This involves ensuring that a function is regularly called to monitor the Ethernet link status and appropriately handle any changes.

With Regards,
