Load-Sharing VLAN Traffic Over Parallel Trunks Example

Using spanning tree port-VLAN priorities, you can load-share VLAN traffic over parallel trunk ports so
that traffic from some VLANs travels over one trunk, while traffic from other VLANs travels over the
other trunk. This configuration allows traffic to be carried over both trunks simultaneously (instead of
keeping one trunk in blocking mode), which reduces the total traffic carried over each trunk while still
maintaining a fault-tolerant configuration.
