Tag VLAN
スイッチ同士をTag接続して、Tagリンクを複数のVLANに所属させる
複数のスイッチを介してVLANが構築できることを確認する
ネットワーク構成
複数のVLANが所属するポートのことをTag ポートと呼びます。
複数のスイッチを介してVLANを構成する場合は、スイッチ同士がつながるポートをTagポートにします。
Untag ポートでは、一つのVLANにしか所属できません。
しかし、１個のポートに複数のVLANのデータが行う場合もあります。
その場合、そのポートをTagポートに設定します。
ポートをTagポートに設定すると、そのポートでMACフレームにVLAN情報を加えて送り出すようになります。
