Edit3: Finally the things have worked. What I did based on @jasonlitka post on another thread. I open up the cli to check the running config file on the ports 3 and 36. I have cleaned all the configurations on each port. So the configurations are below: Switch01 Core(config)#do show running-config interface GigabitEthernet1/0/03 interface gigabitethernet1/0/3 description "Live Esquerda" switchport access vlan 10 ! Switch01 Core(config)#do show running-config interface GigabitEthernet1/0/36 interface gigabitethernet1/0/36 switchport mode general switchport general allowed vlan add 10 tagged switchport general allowed vlan add 1 untagged ! And bang! Machine is addressed and working.
