Load sharing with Summit switches allows you to increase bandwidth and resilience
between switches 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 logical 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.
Load sharing is most useful in cases where the traffic transmitted from the switch to the
load-sharing group is sourced from an equal or greater number of ports on the switch.
For example, traffic transmitted to a 2-port load-sharing group should originate from a
minimum of two other ports on the same switch.
This feature is supported between Summit switches only, but may be compatible with
third-party “trunking” or sharing algorithms. Check with an Extreme Networks
technical representative for more information.
