Bond with Cisco Switch Catalyst 9300L

[MF76]

Does anyone have an idea how to connect a Check Point Appliance 1800 and a Cisco Catalyst Switch 9300L? We have configured a bond (802.3ad) LACP with hashpolicy Layer2+3 on the firewall and a portchannel(Etherchannel) in active mode on the switch. Unfortunately we can't get a connection.

Does anyone have a solution to our problem?

If you are truly stating "portchannel(Etherchannel)" on the Cisco side, that's the issue.   Since you configured the 1800 as LACP, you need to do the same on the Cisco side 😉       If you want to stick with etherchannel, I believe you need to use XOR on the Checkpoint side.  

Either way, both sides don't sound like they match based off your initial statement.

Are you able to share the Cisco port-channel / interface config?

Which firmware version / JHF is used?
