Which statement is true about SW2's Gi0/1 interface configuration in relation to SW1's Dynamic EtherChannel?

In the context of configuring EtherChannel between switches, specifically a Dynamic EtherChannel, it's important to understand the roles of the different modes available—active and passive, particularly in relation to the Link Aggregation Control Protocol (LACP).

When dealing with LACP and the establishment of a Dynamic EtherChannel, one switch can operate in "active" mode while the other operates in "passive" mode. The correct configuration requires that if one switch is set to actively initiate the negotiation for an EtherChannel by sending LACP packets (which is what happens when the switch is set to active), the counterpart must be configured in passive mode. In passive mode, the switch will respond to LACP packets but will not actively initiate the negotiation.

Thus, when SW1 is configured to use a Dynamic EtherChannel and is in active mode, SW2's Gi0/1 interface must be configured as passive to successfully form the EtherChannel. This relationship allows SW2 to negotiate the aggregation of its interfaces successfully while relying on SW1 to initiate the LACP communication.

In this configuration scenario, the statement that the interface must be configured as passive is correct because it ensures that SW2 can join the existing LACP negotiation initiated by SW1 without causing conflicts or failing to
