Load Sharing on the Switch
Summit24e3 Switch Installation and User Guide 73
Load Sharing on the Switch
Load sharing with switches allows you to increase bandwidth and resiliency 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.
Most load-sharing algorithms guarantee 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.
NOTE
Load sharing must be enabled on both ends of the link or a network loop may result. The load-sharing
algorithms do not need to be the same on both ends.
This feature is supported between Extreme Networks switches only, but may be compatible with
third-party trunking or link-aggregation algorithms. Check with an Extreme Networks technical
representative for more information.
Load-Sharing Algorithms
Load-sharing algorithms allow you to select the distribution technique used by the load-sharing group
to determine the output port selection. Algorithm selection is not intended for use in predictive traffic
engineering.
You can configure the address-based load-sharing algorithm on the Summit24e3 switch.
restart ports <portlist> Resets autonegotiation for one or more ports by
resetting the physical link.
show ports {<portlist>} collisions Displays real-time collision statistics.
show ports {<portlist>} configuration Displays the port configuration.
show ports {<portlist>} info {detail} Displays detailed system-related information.
show ports {<portlist>} packet Displays a histogram of packet statistics.
show ports {<portlist>} rxerrors Displays real-time receive error statistics.
show ports {<portlist>} stats Displays real-time port statistics.
show ports {<portlist>} txerrors Displays real-time transmit error statistics.
show ports {<portlist>} utilization Displays real-time port utilization information. Use
the [Spacebar] to toggle between packet, byte,
and bandwidth utilization information.
show sharing address-based Displays the address-based load sharing
configuration.
unconfig ports <portlist> display-string
<string> Clears the user-defined display string from a port.
