エクストリーム・ネットワークス: LACP (XOS)

このポストでは、エクストリーム・スイッチ(XOS) のLACP (Link Aggregation Control Protocol) の設定方法について、ご紹介したいです。


まず今回のトポロジーを説明させてください。

+++++++++++[port 3] <-----> [port 3]+++++++++++
+   SwitchA   +                                      +   SwitchB   +
+++++++++++[port 4] <-----> [port 4]+++++++++++

SwitchA の Port 3 と Port 4 で LACP を実施します。


###### 実行事例 #######
// Switch A と Switch B で、下記のコマンドを実施する //

//Switch A//
* X480-24x(10G4X).4 # enable sharing 3 grouping 3, 4 algorithm address-based lacp

//Switch B//
* X480-24x(10G4X).4 # enable sharing 3 grouping 3, 4 algorithm address-based lacp

//Switch A//
* X480-24x(10G4X).6 # enable ports 3-4

//Switch B//
* X480-24x(10G4X).6 # enable ports 3-4

// 確認するコマンドSwitch A//
* X480-24x(10G4X).7 # show sharing
