Refer to the exhibit. In the Access layer, which switch port will take a discarding state after the RSTP election process is finished?
Switch SW3s port fa0/7
Switch SW3s port fa0/6
Switch SW3s port fa1/4
Switch SW3s port fa1/1
Switch SW7s port fa1/7
Switch SW7s port fa1/6
In this scenario there are two switches in the Access layer SW7 and SW3. According to the information provided on the exhibit, SW3 has a lower Bridge ID than SW7, because the MAC address is numerically smaller. However there are two ports on SW7, one must be in discarding state and the other in alternate state. Both switches will forward BPDUs and compare their information; the BPDU is superior to the other if it has the following qualities: 1. A lower Root Bridge ID 2. A lower path cost to the Root 3. A lower Sending Bridge ID 4. A lower Sending Port ID On SW7, there are two possible ports f1/7 and f1/6. Being f1/7 higher than f1/6, the port 1/7 remains in discarding state, while the port 1/6 remains as alternate.
