Figure 9
Spanning Tree Blocking a Switch-to-Switch Link
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
G8124 uplinks or the Enterprise switch trunk.

During operation, if one G8124 experiences an uplink failure, STP will activate the BLADE
switch-to-switch link so that server traffic on the affected G8124 may pass through to the active
uplink on the other G8124, as shown in
