You can use the switches as stand-alone units or join up to four units with
the VCStack feature. The switches of a VCStack act as a single virtual
unit. They synchronize their actions so that switching operations (such as
spanning tree protocols, virtual LANs, and static port trunks) span across
all of the units and ports. Two 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 stand-alone switch
can consist of ports from the same switch. In contrast, a static
trunk on a stack can have ports from different switches in the same
stack.
