Controller # ap capwap backup primary WLAN-Controller-A
選択したアクセス ポイントの第 1 コントローラを設定します。
ステップ 3
ap capwap backup secondary
例:
Controller # ap capwap backup secondary WLAN-Controller-B
選択したアクセス ポイントの第 2 コントローラを設定します。
ステップ 4
ap capwap backup tertiary
例:
Controller # ap capwap backup tertiary WLAN-Controller-C
選択したアクセス ポイントの第 3 コントローラを設定します。
次の作業
選択したアクセス ポイントの第 1、第 2、および第 3 コントローラの設定が完了したら、show ap name AP-NAME コマンドを使用して設定を確認する必要があります。show ap name AP-NAME コマンドの詳細については、『Lightweight Access Point Configuration Guide for Cisco Wireless LAN Controller』を参照してください。

ハイ アベイラビリティ用の EtherChannel の設定
LAG または EtherChannel は、スタンバイ装置とアクティブ装置の両方の既存のポートすべてを単一の論理ポートにバンドルし、60 Gbps の集約帯域幅を実現します。EtherChannel の作成は、障害に対する保護を可能にします。作成された Etherchannel または LAG は、アクセス ポイントのハイ アベイラビリティを確保するための冗長リンクに使用されます。
