Exchange 2010 CAS Array Logging
My organization is planning to implement an RPC Client Access Pool on our F5 LTMs to support the new architecture employed by Exchange 2010 with regard to the CAS array. My question is in regards to logging client IP addresses for each client that connects through the LTMs for RPC access. What options exist on the LTMs to log the client IP addresses for each email client that connects through our LTMs for Exchange client access? Ideally we would be able to log this perhaps to a file outside of the LTM itself so that support staff could use this information foir client access troubleshooting.

- Joel_MosesNimbostratusBe careful to avoid burying your troubleshooters in data; Outlook will typically initiate between 4-12 RPC sessions to the CAS server per Outlook client. These connections are related to each other but the F5 will have really no way of knowing that and will log the connection details for each independent TCP session. I'm not sure what real value the information would have, as you'll see the logged-in usernames and remote workstation name (all part of the RPC and Kerberos/NTLM transactions) in your Exchange logging just fine. From those two pieces of information, it's just a quick jump to the true source IP.
