@Ganeshm1 - You should be able manage multiple snmp agents with a single trap listener. Make sure snmp agents are configured to send the trap events to the same Mid Server on the same port. 
You should be able to differentiate the messages from these agents using the "Source" and "Node" field in the event table. 

Please note that if the agent implementation is based on more generic net-snmp, then the enterprise id (8072) might be shared with multiple agents.
