120 RackSwitch G8000: Application Guide
Figure 11. Spanning Tree Restoring the Switch-to-Switch Link
In this example, port 10 on each G8000 is used for the switch-to-switch link. To
ensure that the G8000 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 G8000.
