Managing Table Rows From SNMP Managers
Managing Table Rows From SNMP Managers
The zagInEndpointTable, zagInTrapdestTable, and zagInProfileTable in the SNMP
agent’s private MIB contain entries that can be accessed by SNMP managers. The
presence of a RowStatus object (zagInEpRowStatus, zagInTdRowStatus, and
zagInPfRowStatus) with read-write access signifies that managers can add or delete
entries in these tables.
The table row algorithm described in this subsection is based on RFC 1443, Textual
Conventions for Version 2 of the Simple Network Management Protocol (SNMPv2), but
has been modified for SNMP version 1. Refer to RFC 1443 for a detailed description of
the SNMPv2 table row algorithm.
The RowStatus object is expressed as an integer having one of the six values
described in Table 3-6. The RowStatus value supplied by a manager dictates the table
row operation. The two classes of RowStatus values are action and state. Action
values are set by a manager to create and delete entries. State values describe the
availability of an entry for use by the SNMP agent and managers.
Note. The zagInProfileTable entries can only be accessed through SNMP requests received
though NonStop Kernel IPC calls if the Processor/Accessor ID (PAID) of the manager process
is compatible with that of the agent process. In Figure 2-5
, the authentication table permits the
SNMP agent to accept Get and GetNext requests from any SNMP manager belonging to the
“public” community, as well as Set requests sent under the “Private” community from the
SNMP manager whose address is 130.252.15.230. The zagInProfileTable objects are not
accessible through TCP/IP’s UDP transport protocol.
Table 3-6. RowStatus Value Definitions (page1of2)
RowStatus
Value Value Type and Access Effect of RowStatus Value
active (1) A state value that can be
read or written.
Makes the row available for use or
indicates that the row is already
available for use by the SNMP agent.
notInService (2) A state value that can be
read or written.
Makes the row unavailable for use or
indicates that the row exists and is
complete, but is administratively
unavailable to the SNMP agent.
notReady (3) A state value that can only be
read.
Indicates that the row exists but is
incomplete; therefore, the row is
unavailable to the SNMP agent.
