Private MIB Objects Supported by the TCP/IP Subagent
The TCP/IP Subagent also supports private MIB objects that:
•
Provide information about the subagent process itself, such as:
°
The name of the subagent process
°
The processor in which subagent’s primary process is running
°
The name of the TCP/IP process controlling the managed TCP/IP subsystem
•
Allow you to control certain aspects of the subagent’s behavior, such as:
°
Causing a backup process to take over and a new backup process to be
created
°
Controlling the rate at which MIB-II object values are updated
°
Requesting that the subagent refresh MIB-II object values on demand
•
Allow you to monitor information about the subnets associated with the TCP/IP
subsystems:
°
Name of the TCP/IP subsystem being monitored
°
Status of the TCP/IP subsystem
°
Name of the subnets associated with the TCP/IP subsystem
°
Status of the subnets
°
IP address of the subnets
These private MIB objects are defined by HP and reside in the ztsa subtree within the
nonstopsystems subtree registered to HP:
iso (1)
identified-organization (3)
dod (6)
internet (1)
private (4)
enterprises (1)
tandem (169)
nonstopsystems (3)
ztsa (202)
The ztsa objects supported by the TCP/IP Subagent are described in detail in
Table 8-3, Private (ZTSA) MIB Objects Supported by the TCP/IP Subagent, on
page 8-21.
MIB Value Derivation
The TCP/IP Subagent retrieves and alters the values of most MIB-II objects by
exchanging SPI buffers with the HP TCP/IP subsystem. Most values are retrieved from
a token, a field within a token, or a word offset within a field extracted from an SPI reply
buffer in response to various SPI commands.
If the MIB-II object has a directly corresponding SPI attribute, the TCP/IP Subagent
performs a simple SPI interaction with a single subsystem. The TCP/IP Subagent
