Check open TCP/UDP ports with SNMP

Question

I need to find an OID that can be used with "snmpwalk" that describes which TCP/UDP ports that are open and available on my machine (localhost)

A similar post(here) about this was to use:

snmpwalk -v2c -c public localhost tcpConnState
snmpwalk -v2c -c public localhost udpLocalAddress

But as i understand it this only show open connections right now? Anyhow my lab was corrected wrong for using these ones.

Is there any other OID that can show available TCP/UDP ports?

(I am using terminal in Ubuntu)

Here you go!

snmpwalk -v2c -c public localhost tcpConnLocalPort
snmpwalk -v2c -c public localhost1.3.6.1.2.1.6.13.1.3

snmpwalk -v2c -c public localhost udpLocalPort
snmpwalk -v2c -c public localhost 1.3.6.1.2.1.7.5.1.2
