Stacking SFP+ Slots
Two of the four SFP+ slots on the front panel of the switch can be used with stacking transceivers to create a VCStack of up to four switches. The switches of a VCStack act as a single virtual unit. They synchronize their actions so that switching operations, like spanning tree protocols, virtual LANs, and static port trunks, span across all the units and ports. The two main advantages of stacks are:
You can manage multiple units simultaneously, which can simplify network management.
You have more flexibility in how you configure some of the features. For instance, a static port trunk on a
The slots for the stacking transceivers are SFP+ slots 51 and 52.
Note
If you use the switch as a
You can stack any combination of the following switches, up to a total of four switches:
