Does the CAS9855I message reference a port to be permitted when using SSL?

OMWV 11.5. We have are testing OMWV SSL. We are seeing the CAS9855I message below, which looks normal. My question is... after the server name and IP address is listed I see /59080. The number is looks like it changes from on each access to a report. I'm assuming this number is a port number? If so, where is the port number range defined and is it changed dynamically? 13:27:31 CAS9855I Task 0003 has SSLV3 session with CCIPC mcaldtsgoweb01t(134.187.120.37)/59080. <=== port ?? 13:27:31 CAS9855I Task 0003 and CCIPC using 256-bit AES, SHA-1, RSA ("35").

That part of the CAS9855I message doesn't necessarily refer to a port, though that may be a part of it. That particular message argument is a CCI code that CCI uses to distinguish one user from another. It is not something a customer may interpret or use. It's also nothing you should have to allow for.
