Nothing to be worried about. The names of the ports are named according to their name in /etc/services. The names mentioned there are of the first/official services using a specific port, but in practice port assignment may differ. In my Centos 6 /etc/services file, the following assignments are present:

eli 2087/tcp # ELI - Event Logging Integration radsec 2083/tcp # Secure Radius Service rockwell-csp2 2222/tcp # Rockwell CSP2
