SNMP is an Application layer protocol. except few
application layer protocols all other protocols uses any of
the transport layer protocols.

SNMP basically uses UDP as the transport layer protocol. It
can also uses TCP as well.

Now the communication part:
SNMP basically uses two UDP ports 161 and 162 for
communications between SNMP MANAGER and AGENTs.
port 161 is user for REQUEST/REPLY kind of communications.

sending traps to SNMP Manager to inform about some fault in
SNMP Agent.
