*ToF
54. SNMP is a standards-based network management protocol widely used on TCP/IP networks. It provides a method for managing NEs through a central computer that runs network management software, that is, a network management station (NMS). An SNMP NMS and SNMP agent communicate with each other through the TCP protocol.
