Which two LACP modes can be used with EtherChannel configuration?

In an EtherChannel configuration, Link Aggregation Control Protocol (LACP) operates using two specific modes: Active and Passive. The Active mode actively negotiates the formation of an EtherChannel with other LACP-enabled interfaces, sending out LACP packets to learn about remote links. When a port is set to Active mode, it tries to establish a bundled link as a priority and will send its capabilities to create an EtherChannel.

On the other hand, the Passive mode allows the port to receive and respond to LACP packets from other Active ports but does not initiate its own negotiations. If both ends of an EtherChannel configuration are set to Passive, it will not form a successful link bundle, since no LACP packets will be sent from either side.

This dynamic between the Active and Passive modes enables flexible setups in network configurations, ensuring that devices can either initiate or respond to LACP negotiations effectively, thus forming reliable and redundant link bundles for increased bandwidth and fault tolerance.
