MANAGEMENT PROTOCOLS
SNMP is used to configure system parameters, to monitor statistics, and to perform advanced
management tasks.
SNMP
This management protocol specifies how to send information between a network management
system (NMS) and managed devices on a network. Managed devices run a program called an
agent. The agent interprets SNMP requests and responds to them. The NMS communicates with
the agents in the managed devices to:
• set configuration
• get configuration
• get status
A Management Information Base (MIB) defines the configuration and status parameters. The
Internet Engineering Task Force (IETF) specifies standard MIBs for certain types of devices,
ensuring any NMS can manage them. Additionally, vendors can issue proprietary MIBs for their
devices to fit specific needs.
Megabit Modem 500L SNMP Agent
The Megabit Modem 500L provides an SNMP agent that supports several MIBs for
management of the system. The SNMP agent can process datagrams received from the Ethernet
interface. The agent and the protocol stack complies with the following Request for Comments
(RFCs):
• RFC 1155 Structure of Management Information (SMI)
• RFC 1157 Simple Network Management Protocol (SNMP)
• RFC 826 Address Resolution Protocol (ARP)
• RFC 792 Internet Control Message Protocol (ICMP)
• RFC 791 Internet Protocol (IP)
• RFC 768 User Datagram Protocol (UDP)
