Refer to the exhibit. An engineer is building a new Layer 2 LACP EtherChannel between SW1 and SW2 and runs the shown show commands to verify the configuration.

Which additional task must be completed so the switches successfully bundle the second member into the LACP port-channel?

  • A Configure the switchport trunk allowed vlan 300 command on SW1 port-channel 1.
  • B Configure the switchport trunk allowed vlan add 300 command on interface Fa0/2 on SW2.
  • C Configure the switchport trunk allowed vlan add 300 command on SW1 port-channel 1.
  • D Configure the switchport trunk allowed vlan 300 command on interface Fa0/2 on SW1.
Explanation

All physical interfaces in a Layer 2 EtherChannel must have identical trunk parameters, including allowed VLAN lists. The second member interface on SW1 allows only VLANs 100–200, while the bundled links allow 100–300. Adding VLAN 300 to the SW1 port-channel with add appends to the existing list, ensuring LACP can bundle the second interface.
