The F5 will insert a new HTTP Header to the back end node. You should see in the packet:
SSLClientCipher EDH-RSA-DES-CBC3-SHA, version=TLS1.2|TLS1.1|TLS1.0|SSLv3, bits=256|128|40
You can use this info to analyse what your clients are using to connect in via your webserver logs.(Assuming you parse and log that http header in your w3c logs)
