GNS3でアクセスVLANの設定が不安定

GNS3でアクセスVLANが特定のインターフェースだけ入らない。

g1/0の先の設備のみ、pingが飛ばない。
show runでコンフィグを見ると入っている。

S32を再起動、GNSの再起動を行うも事象変わらず。
ふとshow vlanで確認するとvlan 30にg1/0が入っていない。。。

g1/0を一度shutdownして再度vlan 30を設定するも事象変わらず。
仕方なくg1/1にvlan 30を設定したところ反映されpingも通った。

ブログにメモを残し始めたところ、再びping NG。
show vlanを見てみると、g1/0にvlanが設定されていてg1/1が消えている。
