IPアドレスを変更する。
「スタートメニュー」→「設定」(歯車マーク)→「ネットワークとイン
ターネット」→
「イーサネット」→「アダプターのオプションを変更する」→「イーサ
ネット」→
「インターネット プロトコル バージョン 4 (TCP/IPv4)」→「プロパ
ティ」→
「次の IPアドレスを使う」→「IPアドレス」を「192.168.10.100」に設
定「サブネットマスク」を「255.255.255.0」に設定
「デフォルトゲートウェイ」を「192.168.10.1」に設定
【Cisco】#8初期設定 ルータの設定1(共通)
FORSE
手順1
ルータは起動に時間がかかります
セットアップモードが起動したら、noと入力、もしくはcttl+c
手順2
メッセージが表示され、Enterキーを押します。Router>のプロンプトが
表示されます
手順3
特権モードに移行します。Router#のプロンプトが表示されます
手順4
グローバルコンフィグレーションモードに移行します。Router(config)#
が表示されます
手順5
ホスト名を設定します。設定後プロンプトがホスト名に変更された事を確認
します。ホスト名は講師が指示します
手順6
xxxx
手順7
リモートログイン許可の設定
