Solution:

Make sure the server IP where you are running the snmpwalk command from has been added as an snmp client and it's IP allowed on the router/switch that you are trying to query.

for my case am trying to query a juniper switch, so i added the line below:

# set snmp community public clients 10.0.43.18/32  

# commit 

configuration check succeeds

commit complete

Trying the snmpwalk command again: problem solved
