Alive, Not classified

[nk_dubey1]

Hi,

While Discovery bunch of my IP returning this error. I checked the log and it indicates that IP is not Active but it's Alive. I can see refusal on many ports. I have below questions in the discovery:

(1) What is the difference between Active and Alive. Does

(2) What Discovery use for fetching information TCP or UDP? Also in which order.

(3) Alive, Not classified (Does this means Discovery was able to ping IP, but it received negative response from port?)

Any easy way to solve these kind of issue.

Ssh 22, wmi 135, and snmp 161 are the classifier ports. ...and WBEM - SLP 427, CIM 5989 and 5988. Generally, classification is a function of which of these ports is open.
