Figure 10 Spanning Tree Restoring the Switch-to-Switch Link
In this example, port 10 on each G8124 is used for the switch-to-switch link. To ensure that the
G8124 switch-to-switch link is blocked during normal operation, the port path cost is set to a higher
value than other paths in the network. To configure the port path cost on the switch-to-switch links
in this example, use the following commands on each G8124.
