See article for "Diagnosing IPsec Tunnel Issues" as from what you say the F5 device does not add the traffic from the switch to the tunnel, if you dont see issues and a tcpdump also show that F5 is sedning the traffic to the other device in the VPN tunnel then see why the replies don't come back as the issue could be not from the F5 config but the Firewall VPN config.
