  1. The ports have disabled auto-negotiation.
  2. One port is supporting auto-negotiation, while auto-negotiation is disabled on the port of the other switch.
  3. The port of one switch is operating using half duplex mode, while the port of the other switch is using full duplex mode.
  4. A Fast Ethernet port cannot communicate directly with a Gigabit Ethernet port.
