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 stand-alone switch
has to consist of ports from the same switch. In contrast, a static
trunk on a stack may consist of ports from different switches in the
same stack.
The slots for the stacking transceivers are SFP+ slots 51 and 52.
Note
If you use the switch as a stand-alone device, you can use the slots
with regular SFP and SFP+ transceivers by disabling the VCStack
feature. See Chapter 5, “Configuring the Switch for Stand-alone
Operations” on page 77 for instructions.
You can stack any combination of the following switches, up to a total of
four switches:
