snmpwalk shows no response but another SNMP client & Wireshark works fine

I am not getting SNMP traps using snmpwalk. However another SNMP client ("ManageEngine") on the same Windows PC, easily gets all the traps. Also the Wireshark shows that the traps are arriving quite fine.

Please guide me, am I doing something wrong?.

the command:

snmpwalk.exe -v 2c -c public -t 10 IP:Port

Timeout: No Response from IP:Port

You are able to receive trap because your manager on local machine is listening to traps send by remote machine , at port 162.

This does not mean snmpwalk will work. Because in that you are client and sending snmp query to remote host at port 161.

Reason for not responding May be access control list at remote end. Wrong community string.. Please check at very first that your server is actively listening for query

Check can be done by nmap for listening

Nmap -sU ip -p 161

snmpwalk is not suppose to receive any traps by design. It is used to traverse the MIB tree using GET-NEXT, GET-BULK requests.

Instead you should be using snmptrapd to receive traps.
