hello I would like to have your understanding on this problem solving
I don't speak much English but I'll try to explain
I have two subnets here and two vlan that happens I know very well the STP ptotocolo but I observe that there are no loops and I have redudancia in the network and I see this and I say and because there is a blocked port
data I have the interfaces in trunk and native mode because the one that is not colored is a vlan 99 for native traffic
then what would be the cause of this problem that there are no loops

STP is a network loop prevention protocol. this port will unblock when there is a change in topology that favors this path the the root bridge.
