READWRITE
READWRITE. An access mode that lets SNMP managers associated with a particular
community both retrieve and modify the values of MIB objects. MIB objects that have
read-write access can be modified. MIB objects that have read-only or read-write
access can be read.
Request for Comments. A document in a series containing surveys, measurements, ideas,
techniques, and observations, as well as proposed and accepted standards for the
Internet suite of protocols, such as TCP/IP and SNMP.
request message. An SNMP message that initiates data flow between the SNMP manager
and the SNMP agent. A request message may contain a SetRequest PDU, a
GetRequest PDU, or a GetNextRequest PDU.
response message. An SNMP message that contains a GetResponse PDU with the reply
to a request message.
Response operation. An SNMP operation that returns a response to the originator of a
Get, GetNext, or Set request. It contains identifiers that associate it with the previous
PDU and provide information about the status of the response (error codes, error
status, and a list of additional information).
RFC. See Request for Comments.
RMS. See Rule Management Services.
root. The unlabeled top of an object tree.
routing distributor filter. An event filter used by the EMS Trap Subagent to specify where
to route trap messages. The filter contains a destination statement that identifies the
SNMP agent as the routing destination. The filter can also contain specifications for
selecting events to convert traps.
RowStatus object. A MIB table variable that is used to manage the creation and deletion of
conceptual rows, and is used as the value of the SYNTAX cause for the status column
of a conceptual row.
RowStatus values. The values of the status column of a conceptual row. These values are:
active Indicates that the conceptual row is available for use by the managed
device.
notInService Indicates that the conceptual row exists in the agent, but is unavailable for
use by the managed device.
notReady Indicates that the conceptual row exists in the agent, but is missing
information necessary in order to be available for use by the managed
device.
