что такое 172.17.0.2 ? другой хост ?

Все пингуется и сам интерфейс и сеть к которому он подключем, судя во всему у тебя он тоже поднялся и работает раз ты его пингуешь, а вот почему дальше не идут пинги это другой вопрос, смотри и вообще потрасируй посмотри де умирает..
и сделай
sh int vlan15
sh int FastEthernet0/2/0
