Catalyst 2960x堆疊是Cisco用戶非常普遍的問題。您對Catalyst2960-X和Catalyst2960-XR系列的關鍵堆疊模塊瞭解多少？2960-X和Catalyst 2960-XR上可以使用多少種類型的堆疊模塊？在下麵的部分中，我們將分享三個2960-X/Catalyst 2960-XR堆疊模塊的主要比較和功能。
Cisco Catalyst 2960-X和Catalyst 2960-XR系列交換機提供三種類型的堆疊模塊：
C2960X-Stack:Cisco Catalyst 2960-X FlexStack Plus堆棧模塊
c2960x-fiber-stk:Catalyst 2960-x FlexStack擴展堆棧模塊
C2960X-Hybrid-STK:FlexStack擴展混合動力模塊
閱讀堆疊模塊的詳細功能： C2960X-STACK, C2960X-FIBER-STK, C2960X-HYBRID-STK
堆棧模塊插槽位置:
FlexStack Plus模塊（C2960X-Stack）：
FlexStack Plus模塊允許在銅纜上堆疊，並在短距離（高達3米[10英尺]）內提供高達80 Gbps的高頻寬。模塊支持0.5 m、1 m或3 m長（1.5 ft、3 ft或10 ft）的堆疊電纜。
CAB-STK-E-0.5M= (0.5-m [1.5-ft] cable)
CAB-STK-E-1M= (1-m [3-ft] cable)
CAB-STK-E-3M= (3-m [10-ft] cable)
FlexStack Plus模塊
1.1 具有flexstack plus模塊的堆疊拓撲
在一個配線櫃中最多可以有八個Cisco Catalyst 2960-X或2960-XR系列交換機，它們可以堆疊在帶有FlexStack Plus模塊和電纜的環形拓撲中。環形拓撲結構有助於確保堆疊的冗餘。
短程高頻寬疊加
Cisco FlexStack擴展光纖模塊 (C2960X-FIBER-STK):
該模塊允許在SFP+埠上堆疊，並在更長的距離內提供高達40 gpb的堆疊頻寬。它可以用於在建築物不同樓層的配線間或校園內不同建築物之間堆疊交換機。
FlexStack擴展光纖模塊有兩個SFP+埠。相容性矩陣中列出了這些埠上支持的SFP+收發器。根據交換機之間所需的距離選擇合適的SFP+收發器。
FlexStack擴展光纖模塊
2.1 使用FlexStack擴展光纖模塊的堆疊拓撲
單個Cisco Catalyst 2960-X或2960-XR系列交換機分佈在建築物不同樓層或校園不同建築的多個配線間中，可以使用FlexStack擴展光纖模塊進行堆疊。最多可以將八個開關堆疊在一起。堆疊頻寬為40 Gbps。
在建築物的多個樓層堆疊
在校園內跨多個樓層和多個建築物堆放
FlexStack擴展混合動力模塊（C2960X-Hybrid-STK）：
FlexStack擴展混合模塊有一個SFP+埠和一個銅質FlexStack+埠。
光纖埠允許您長距離擴展堆疊。相容性矩陣中列出了這些埠上支持的SFP+收發器。根據交換機之間的距離選擇合適的SFP+收發器。
銅質flexstack plus埠允許交換機與flexstack plus堆棧堆疊。此埠支持銅FlexStack Plus電纜：
CAB-STK-E-0.5M= (0.5-m [1.5-ft] cable)
CAB-STK-E-1M= (1-m [3-ft] cable)
CAB-STK-E-3M= (3-m [10-ft] cable)
FlexStack擴展混合模塊
3.1 使用FlexStack擴展混合模塊的堆疊拓撲
FlexStack擴展混合模塊允許您將現有的交換機堆棧和分佈在建築物不同樓層或校園多個建築物的多個配線間的新交換機組合在一起。
flexstack擴展混合模塊上的銅flexstack plus埠應連接到c2960x堆棧模塊上的flexstack plus埠。
FlexStack擴展混合模塊上的光纖埠可用於遠距離連接交換機。
