This section describes how to configure and manage link aggregation using the Command Line Interface (CLI), including Link Aggregation Control Protocol (LACP), to increase the link speed and redundancy for higher availability.
MultiLink Trunking (MLT) with LACP manages switch ports and port memberships to form a link aggregation group (LAG). Configure LACP to allow dynamic bundling of physical ports to form a single logical channel.
You can describe the LACP in terms of link aggregation operations within a single system. You can configure a single piece of equipment so it contains more than one system (from the point of view of the link aggregation operation).
Changes to LACP made at the global level overrides and resets all port level settings.
Important
After you globally configure the LACP system priority, it applies to all LACP-enabled aggregators and ports. After you enable the LACP on an aggregator or port, it uses the global system priority value.
After you make a timer change, restart the LACP (globally or on the port) so the changes are consistent across the link.
Important
Configuration changes to LACP timers are not reflected immediately. LACP timers are not reset until the next time LACP is restarted globally or on a port. This action ensures consistency with peer switches.
The switch does not support standby ports for LACP aggregation groups.
