I personally do not want to be a CA network expert ;-)
But I have CA errors reported by my IOCs, I hope ethereal could help me
here.

Yes, by default.
But you can decode packets coming and leaving from non default ports
with a specific protocol.
You can definitely do this through the ethereal GUI. I am not sure if it
is possible from the command line or a config file.

I use different ports for several iocs running on same computer.
This is particularly convenient in R&D mode, where you can have 1 IOC
per connected device (or rather 1 IOC per small group of devices).
They are issues with port usage. I believe some records needs to have
linked PVs in the same IOC (IN_DBLINK? such as INP of CALC record?).
