10.1 SNMP management
Introduction of SNMP
SNMP (Simple Network Management Protocol) is an internet-standard protocol
for managing devices on IP networks. It is used mostly in network management
systems to monitor network-attached devices for conditions that warrant
administrative attention.
Work Mechanism of SNMP
SNMP includes 2 parts: NMS and Agent:
NMS: Network Management Station. Software runs on the manager. The
common management platforms are "Quid View", "Sun Net Manager" and "IBM
Net View". Agent is the software of the server running in the network device.
NMS can send "Get Request", "Get Next Request" and "Set Request" message
to Agent. After Agent gets those messages, it will read or write according to the
message type to create Response message and send the Response message
back to NMS. Agent will also send Trap message to NMS when the device is
abnormal.
SNMP Version
Currently SNMP Agent of the device supports SNMP V3 and it is also compatible
with SNMP V1and SNMP V2C. It is authenticated by user name and password in
SNMP V3.
SNMP V1 and SNMP V2C adopt authentication of Community Name. The SNMP
message of the community name which is not authenticated will be discarded.
SNMP community name defines the relationship of SNMP NMS and SNMP Agent.
User can choose the following one or more features related to community name.
