I wanted to get more info on this, Currently SNMP D-Bus service on the 
BMC does the validation for whether the IP is reachable or not as part 
of configuration.

Suppose if admin configures the hostname/ip which is valid end 
point(pingable hostname/ip) but not the SNMP trapdaemon, In this 
scenario what is customer expectation?

SNMP trapdaemon works on UDP, and the trapdaemon(162) listens only the 
trap messages not the SNMP agent messages.

*BMC uses the SNMP for sending the trap messages to the SNMP trapdaemon.*

Below link seems useful if BMC would have been SNMP client(sending 
messages to port 161) and SNMP agent is sitting outside the BMC and on 
BMC I run the command SNMPwalk to find that the configured IP address is 
SNMP agent or not which is not the case here.
