Figure 12 shows an example configuration. In this example, the QSFP+
stacking ports labeled 49 and 61 on one member are connected to the
QSFP+ stacking ports labeled 49 and 61 on the other stack member,
respectively.

Where network connectivity uptime is a major criteria, you can use virtual
chassis stacking to create highly reliable network configurations. The
network shown in Figure 13 on page 39 employs redundant links and
switches to create a stacked network that offers extremely reliable user
connectivity.
Employing link aggregation, rather than spanning tree, to manage the
parallel paths enables the bandwidth of both data links to be utilized under
normal conditions while enabling a single data link to operate should its
partner link fail.
