Question 859

Refer to the exhibit. An engineer ts building a new Layer 2 LACP EtherChannel between SW1 and SW2, and they executed the given show commands to verify the work. Which additional task must be performed so that the switches successfully bundle the second member in the LACP port-channel?

    Correct Answer: C

    To ensure that the EtherChannel can properly bundle all the specified VLANs, you must add VLAN 300 to the allowed VLAN list on the port-channel interface. This ensures consistency across both member interfaces of the EtherChannel, rather than configuring it on individual interfaces, which could lead to inconsistencies and potential misconfigurations. Therefore, the correct command is to configure the 'switchport trunk allowed vlan add 300' on SW1 port-channel 1 to include this VLAN without overriding the existing VLANs.

Wrong, if we do switchport trunk allowed vlan 300 that replaces the previous allowed vlans so they are no longer allowed. You have to "add" vlan 300

You always update the information within the Portchannel information..

C is correct

RynurrOption: C

I agree with oatmealturkey, so "C" is the correct answer.

geweOption: C

I was thinking about option B, but it is on SW2 which is configured correctly, so in this case we can add vlan 300 to po1, which makes C best choice

Configure the switchport trunk allowed vlan 300 command on interface Fa0/2 on SW1: This would only configure VLAN 300 on a single physical interface (Fa0/2) and wouldn't include it in the EtherChannel (port-channel 1). By adding VLAN 300 to the allowed VLANs on SW1's port-channel 1, both members of the EtherChannel will be able to carry traffic for that VLAN, allowing it to participate in the LACP bundle. C. Configure the switchport trunk allowed vlan add 300 command on SW1 port-channel 1. The show run interface commands reveal that both switches (SW1 and SW2) have LACP configured on their respective interfaces (FastEthernet 0/1 and 0/2) and are assigned to channel-group 1. The allowed VLANs on SW1's port-channel 1 are currently 100 and 200, but not 300. VLAN 300 is missing from the allowed VLANs on the port-channel interface. By issuing the switchport trunk allowed vlan add 300 command on SW1's port-channel 1, you'll enable that port-channel to carry traffic for VLAN 300 in addition to the already allowed VLANs 100 and 200
