To prevent a network loop among the switches, STP must block one of the links
between them. In this case, it is desired that STP block the link between the BLADE
switches, and not one of the G8000 uplinks or the Enterprise switch trunk.
During operation, if one G8000 experiences an uplink failure, STP will activate the
BLADE switch-to-switch link so that server traffic on the affected G8000 may pass
through to the active uplink on the other G8000, as shown in
