Does anyone know if Port 9980 is important?

Hi,

I noticed when I enter the following in CLI:

 

nmap --script ssl-enum-ciphers -p 9980 <IP Address here> (ie. 10.x.x.1)

 

it shows port 9980 is vulnerable to TLSv1.0. Is there a way to correct this? Is port 9980 important? Is there a way to close port 9980?

 

Thanks,
