Port Commands
Load Sharing
Load sharing with Switch 9000 Switches allows you to increase
bandwidth and resilience by using a group of ports to carry traffic in
parallel between Switches. The sharing algorithm allows the Switch to
use multiple ports as a single logical port. For example, VLANs see the
load-sharing group as a single virtual port. The algorithm also
guarantees packet sequencing between clients.

If a port in a load-sharing group fails, traffic is redistributed to the
remaining ports in the load-sharing group. If the failed port becomes
active again, traffic is redistributed to include that port.
