A network administrator is configuring an EtherChannel trunk link to add additional allowed VLANs to pass the link. Which statement describes the process of this change?

• The change should be made on the port channel interface at both sides.
• The change should be made on each physical interface of the EtherChannel.
• The change only needs to be made on one side of the EtherChannel link, because it will automatically propagate to the other side.
• The change can be made on the port channel interface at one side and the change will be negotiated to the other side.

Explanation: If a configuration change needs to be made after an EtherChannel is established, the change should be made in port channel interface configuration mode. After the port channel interface is configured, any configuration that is applied to the port channel interface also affects individual interfaces. However, configurations that are applied to the individual interfaces do not affect the port channel interface. Also, an EtherChannel trunk link is established if the parameter (in this case, allowed range of VLANs) matches.
