Etherchannel(LACP) configuration in Firepower(FTD w/ FMC) inline mode

[HWAN]

Hi Teams,

My customer is using FTD 2100 series inline mode like picture1.

In this situation, my customer want to extend one more interface like picture2.

In this situation, I will configure Etherchannel in 2 points(FTD's uplink and downlink).

Plus, FW&SW need Etherchannel configuration also, right?

I make sure that FPR-2100 can configure LACP interface in FMC.

Is there more configuration? Please give me some tips designing the topology.

Thank you.

When you move from a single link to LACP you need a maintenance window to convert to Port-channel: look at the below guide :

Hi

 That´s rgith, if you configure Etherchannel in one side, you need to do the same on the other side. Aside from configuring both sides, you probably need to configure as a trunk and add the approprated vlans if that is the case.

Hi,

Thanks for your solution.

Let me set the LACP configuration on the FMC.
