SNMP Management Stations

An SNMP Network Management Station is a dedicated or shared network
device that is the client in the client-server model. The management
station can run an application specifically written for the RA 6300 (or
other Remote Annexes) and its MIBs (e.g., Annex Manager), or a generic
application that communicates with other non-Bay Networks devices
(e.g. SunNet Manager, , HP/OpenView,
generic application must include the definitions of the MIBs supported
by the RA 6300.
The SNMP agent
processes get, set, get-next commands, returns a response
indicating the command's success or failure, and returns the requested data for
get and get-next comm
the
these commands in greater detail).

Message Delivery

SNMP messages are encapsulated in UDP datagrams. The UDP layer
does not guarantee delivery. The RA 6300 uses a time-out and retry
mechanism to guarantee the SNMP command's delivery. If a time-out
occurs, the RA 6300 does not know if the agent did not receive the
command or if the agent's response was lost.
The SNMP agent can generate an unsolicited trap command and send it
to one or more network addresses. Receivers of traps, i.e., trap hosts, do
not respond to the SNMP agent (for more details, see
and Traps on page 2-60).
The RA 6300 supports only the cold-start, link-up, and
link-down traps defined in MIB-II.
