備忘録。

要望も頂いていましたが、新しい機種についてもEtherChannel(Port-Channel)の最大数をまとめてみました。

○最大Port-Channel数
※OSベースのConfiguration Guideでの確認なのでOSのバージョンが変わるとちょっと違うかも
・Catalyst2960-X : 24 (FlexStack Plusも同じ)
・Catalyst2960-XR : 24 (FlexStack Plusも同じ)
・Catalyst3650 : 128 (StackWise-160も同じ)
・Catalyst3850 : 128 (StackWise-480も同じ)
・Catalyst4500系(Standalone): 64
・Catalyst4500系(VSS) : 256
・Catalyst6500系(Sup720/Standalone): 128
・Catalyst6500系(Sup720/VSS) : 512
・Catalyst6500/6800系(Sup2T/Standalone): 128
・Catalyst6500/6800系(Sup2T/VSS) : 512
 ※Cat6500とCat6800は今のところ同じSup2Tで同じIOSを使っていますので。


前回記載の内容
※設定できる値も 1 から 最大数の値 まで
・Catalyst2960 : 6(FlexStackも同じ)
・Catalyst3560 : 48
・Catalyst3560-E : 48
・Catalyst3560-X : 48
・Catalyst3750 : 48(Cross-Stack EtherChannelも同じ)
・Catalyst3750-E : 48(Cross-Stack EtherChannelも同じ)
・Catalyst3750-X : 48(Cross-Stack EtherChannelも同じ)
・Catalyst4500 : 64
・Catalyst4900 : 64
・Catalyst6500(SX) : 128
・Catalyst6500(SXI) : 512(VSSの場合だけ?)

追記。

ふと、
「Cat2960PlusやCat2960SFについては書いてないな」
と思い調べたらコンフィギュレーションガイド上では
15.2(2)E
以降ではCat2960,Cat2960S,Cat2960Plus,Cat2960SFもEtherChannelの最大数は
24
になっているようです。

---------------------------------------------------------------------------------
Do not try to configure more than 24 EtherChannels on the switch.
---------------------------------------------------------------------------------

では
「Cat3560XやCat3750Xも 15.2(2)E 以降で増えているかな?」
と思って調べてみたら前と変わらず
48
のままでした。

---------------------------------------------------------------------------------
Do not try to configure more than 48 EtherChannels on the switch or switch stack.
---------------------------------------------------------------------------------

ただCat2960SのRelease Noteを見てもEtherChannelの最大数が増えたというような記載もちょっと見つけられなかったので一回試してみたいな~とも思いました。
