目次

マルチキャリア対応 SIM を使用した LTE 接続設定


MA-S1xx v5.4.0, MA-E3xx v5.3.0, MA-X3xx v6.0.0 から、マルチキャリア対応 SIM (SORACOM planX1, planX3 など) での自動キャリア変更機能に対応しました。

[参考] マルチキャリアに対応する SIM のキャリア切り替えの実装例 - SORACOM 公式ブログ


設定

WebUI にメインとして使用するキャリアと、バックアップに使用するキャリア 2 つの PLMN を設定します。

Setup Primary-PLMN, Secondary-PLMN

※ キャリア切替のトリガーとして使用する、ICMP による Peer 1)への疎通確認機能は強制的に有効化されます。


動作確認

疎通確認2) NG が 3 回連続すると、PPP 接続を切断してメイン回線からバックアップ回線への切替が行われます。

※ 意図的に疎通確認 NG を発生させるため、今回は PPP 接続完了後に iptables で ppp0 からのパケットを落とす設定をしています。

  • PPP 受信パケットを全部落とす
iptables -I INPUT -i ppp0 -j DROP
  • 上記フィルター設定を消して元に戻す
iptables -D INPUT 1
