In an Ethernet network, switch 32
has received the following BPDUs from its neighbours :
[R=9,C=21,T=19.2]
on port 1[R=9,C=12,T=42.1]
on port 2[R=25,C=5,T=25.2]
on port 3[R=9,C=5,T=46.3]
on port 4
What is the state of each port of this switch if all the links attached to this switch have a cost of 1?
