Hi Team,

We are using NMAP version 7.7 for port scanning while doing UDP scan using the below command we observed port 161 
skipped we never faced that kind of issue, are we missing anything.

<!-- Nmap 7.70 scan initiated Thu May 14 18:05:01 2020 as: nmap -sU -sV -p- -Pn -&#45;max-retries 1 
-&#45;version-intensity 0 -&#45;min-hostgroup 32 -&#45;max-scan-delay 10ms -vvv -&#45;reason -&#45;webxml -oA 
20.5_cloud_csd_deploy_udp_report 10.15.166.108 -->

<port protocol="udp" portid="159"><state state="open|filtered" reason="no-response" reason_ttl="0"/><service 
name="tcpwrapped" method="probed" conf="8"/></port>
<port protocol="udp" portid="160"><state state="open|filtered" reason="no-response" reason_ttl="0"/><service 
name="tcpwrapped" method="probed" conf="8"/></port>
<port protocol="udp" portid="162"><state state="open|filtered" reason="no-response" reason_ttl="0"/><service 
name="tcpwrapped" method="probed" conf="8"/></port>
<port protocol="udp" portid="163"><state state="open|filtered" reason="no-response" reason_ttl="0"/><service 
name="tcpwrapped" method="probed" conf="8"/></port>

Also in Nmap_IP_Discovery scan using below command we found port id 1,6,17 are as open, does it mean the target machine 
supported communication over ICMP, TCP, and UDP if my understanding  correct so what should be ideal input for a 
machine where product allowed only TCP traffic.

<port protocol="ip" portid="1"><state state="open" reason="port-unreach" reason_ttl="60" reason_ip="10.15.166.112"/>
Service name="icmp" conf="8" method="table"/></port>
<port protocol="ip" portid="6"><state state="open" reason="proto-response" reason_ttl="60"/>
<service name="tcp" conf="8" method="table"/></port>
<port protocol="ip" portid="17"><state state="open" reason="port-unreach" reason_ttl="60"/>
<service name="udp" conf="8" method="table"/></port>

Thanks in advance !

Thanks and Regards,
