ports 1 and 2.
4. Status Results
After you connect the uplink port 1 on IES-2000 to port 2 on the ES-4024, the state of
port 2 becomes BLOCKING.
To test the RSTP/STP mechanism, disconnect the Ethernet cable between uplink port
1 on the IES-5000 and port 1 on the ES-4024. The computers can still access the
network through the CPE devices since traffic now goes through IES-2000.
Check the state of port 2 on the ES-4024. It has become FORWARDING.
