SNMP_Sample

1. Examine the details in the first packet. What transport layer protocol is being used?
2. What is the first packets destination port number? What is the significance, if any, of this port number?
3. What is the first packets source port number? What is the significance, if any, of this port number?
4. Consider all 8 packets in this pcap file. Taken together, are they part of a connection-oriented message between two endpoints? Why or why not?

This is wiresharks. I need explanations more than anything.
