概要

ほとんどの環境では、非同期および ISDN の両方のユーザから着信コールを受けられるようにアクセスサーバを設定しておく必要があります。アクセスサーバが設定されていると、どちらのユーザも物理的に接続されているかのようにスムーズにネットワークに接続できます。このような設定は、移動中のユーザや在宅勤務のユーザ、Small Office-Home Office（SOHO）サイトがネットワークに接続する場合にもよく使用します。

この文書では、着信の非同期および ISDN のコールを ISDN T1 PRI 回線で受信できるようにアクセスサーバを設定する方法を説明します。設定には、コール受信のために最小限必要なネットワークアクセスサーバ（NAS）のセットアップが含まれています。必要に応じて、この設定に機能を追加できます。

確認

ここでは、設定が正しく機能していることを確認するために使用する情報を示します。

一部の show コマンドはアウトプットインタープリタツールによってサポートされています（登録ユーザ専用）。このツールを使用することによって、show コマンド出力の分析結果を表示できます。

show isdn status：ルータが ISDN スイッチと正常に通信していることを確認します。出力で、レイヤ 1 ステータスが ACTIVE、レイヤ 2 ステータスが state = MULTIPLE_FRAME_ESTABLISHED となっていることを確認します。このコマンドは、通信中のコールの数も表示します。詳細については、「 show isdn status コマンドを使用した BRI のトラブルシューティング」を参照してください。
show ppp multilink：通信中のマルチリンクのバンドルに関する情報を表示します。このコマンドを使用して、マルチリンク接続を検証します。
show dialer [interface type number]：DDR に設定されたインターフェイスの一般的な診断情報を表示します。ダイヤラが正常に始動すると、「Dialer state is data link layer up」というメッセージが表示されます。physical layer up が表示される場合、回線プロトコルは起動しましたが、ネットワーク制御プロトコル（NCP）は起動していないと推測されます。ダイヤリングを開始したパケットのソースアドレスと宛先アドレスが、「Dial reason line」の行に表示されます。この show コマンドでは、タイマーの設定と接続がタイムアウトするまでの時間も表示されます。
show caller user username detail ：特定ユーザのパラメータ（たとえば割り当てられている IP アドレス、PPP および PPP バンドルパラメータ）を表示します。所有している Cisco IOS ソフトウェアがこのコマンドをサポートしない場合には、show user コマンドを使用します。
show dialer map：設定したダイナミックおよびスタティックのダイヤラマップを表示します。このコマンドを使用して、ダイナミックダイヤラマップが作成されているか確認できます。ダイヤラマップがないと、パケットを送信できません。

show のサンプル出力

次に、成功したコールに対する show コマンドの出力を示します。太字で書かれている部分とコメントに注意してください。自分が得た出力と、ここに示される出力とを比べてください。

T1/56K回線のループバックテスト：このドキュメントを使用して、ルータのT1ポートが正しく機能していることを確認します。

トラブルシューティングのためのコマンド

注：debug コマンドを使用する前に、「debug コマンドに関する重要な情報」を参照してください。

debug dialer：ダイヤラインターフェイスで受信されたパケットに関する DDR デバッグ情報を表示します。この情報により、ダイヤラインターフェイスを使用する対象トラフィックが存在することを確認できます。
debug isdn q931:ISDNネットワーク接続（レイヤ3）のコールセットアップと切断を表示します。
debug modem：アクセスサーバ上のモデム回線動作を表示します。モデム回線の状態が変化すると出力が表示されます。
debug modem csm：内部デジタルモデムを搭載するルータ上で発生した、コールスイッチングモジュール（CSM）の問題をトラブルシューティングすることができます。このコマンドを使用すると、着信および発信のコールのスイッチングについて、完全なシーケンスをトレースできます。
debug ppp negotiation：PPP トラフィックと交換に関する情報を表示して、Link Control Protocol LCP）、認証、および Network Control Protocol（NCP）のネゴシエーションを行います。PPP ネゴシエーションが成功すると、最初に LCP ステートが開き、次に認証が行われ、そして最後に NCP のネゴシエーションが行われます。Maximum Receive Reconstructed Unit（MRRU）などのマルチリンクパラメータは、LCP ネゴシエーションの間に確立されます。
debug ppp authentication：CHAP パケット交換および Password Authentication Protocol（PAP）交換などを含む、PPP 認証のプロトコルメッセージが表示されます。
debug ppp error ：PPP 接続のネゴシエーションと操作に関するプロトコルエラーとエラー統計情報を表示します。
