Introduction:
It seems that the Spectrum gateway probe is utilizing the Java Remote Debug protocol, using port 4321. Is this intended? Security scans have picked up on this, and isn't generally allowed on many sites.
Question:
How is port 4321 used by the spectrumgtw probe?  Is it needed for the probe to function properly?
Environment:
UIM 8.51
Spectrum 10.2.3
spectrumgtw 8.65HF3
java_jre  1.80
Answer:
Port 4321 is used by the development team for debugging the spectrumgtw probe.  This port is not mandatory for the correct operation of this probe.
