(2) Checking whether communication with the relevant destination address is possible

Use the ping <IPv4 Address> specific-route source <Source Address> command at each interface of the Switch used for load balancing to confirm that the interface can communicate with the remote system. As <Source Address> of the ping command, specify the local IPv4 address on the Switch of the interface performing load balancing.
