We have two stack of 3750-X switchs interconnected through LACP, and a CheckPoint Firewall connected to one of the stack. The Firewall use a LACP bond to connect to the 3750-X Stack. On the Cisco switches we don't use any Layer3 functionality.
Since the switch are used in Layer2 mode, can we define the a load balancing method that use IP informations ?
For example Can we change the load balancing method from src-mac to src-dst-ip ?

As far as i know. Yes we can configure loadbalancing based on source & destination IP. The switch can understand it in though in layer2 mode.

Hi,
yes you can choose the method of Load balancing in LACP:
port-channel load-balance {dst-ip | dst-mac | src-dst-ip | src-dst-mac | src-ip | src-mac}
Configure an EtherChannel load-balancing method.
The default is src-mac.
Select one of these load-distribution methods:
•dst-ip—Load distribution is based on the destination-host IP address.
•dst-mac—Load distribution is based on the destination-host MAC address of the incoming packet.
•src-dst-ip—Load distribution is based on the source-and-destination host-IP address.
•src-dst-mac—Load distribution is based on the source-and-destination host-MAC address.
•src-ip—Load distribution is based on the source-host IP address.
•src-mac—Load distribution is based on the source-MAC address of the incoming packet.

Hello, It's completed in these mechanisms (Q1 2023):

BTW, LB defaults and choices can vary per platform.

Yup, as also noted by other posters.
3750 series can work with L3 info even in L2 mode.
