TCP/IP Subagent
The TCP/IP Subagent supports the MIB-II groups that allow TCP/IP resources
(including Parallel Library TCP/IP, and NonStop TCP/IPv6) on NonStop systems to be
managed from SNMP managers. It also supports additional private MIB objects
defined by HP that let you monitor and manage the subagent itself. This section
describes the TCP/IP Subagent and the MIBs it supports.
Architectural Overview
The TCP/IP Subagent supports management of HP TCP/IP resources and the
subagent in the following ways:
•
The TCP/IP Subagent implements five of the MIB-II groups defined in RFC 1213
that describe TCP/IP resources.
•
Additional private objects in the TCP/IP Subagent’s MIB defined by HP allow the
TCP/IP Subagent to be monitored and managed through SNMP.
•
The TCP/IP Subagent also includes the set of private MIB objects which provides
information about the subnets associated with the TCP/IP subsystems.
The following interaction between the SNMP agent, the TCP/IP Subagent, and the
managed TCP/IP resources is illustrated in
Figure 8-1, Architectural Overview of the
TCP/IP Subagent,
on page 8-2:
•
The SNMP agent receives and authenticates SNMP request messages regarding
HP TCP/IP resources and forwards authenticated requests to the TCP/IP
Subagent with which it is communicating.
•
The TCP/IP Subagent translates the request, retrieves the requested objects from
a cache of MIB-II object values, and returns them in an SNMP response to the
SNMP agent.
•
Independent of SNMP requests, the TCP/IP Subagent periodically updates the
MIB-II object cache using the Subsystem Programmatic Interface (SPI) to
exchange messages with the Subsystem Control Point (SCP) process or the LAN
Management Library (ZLANSMRL).
Requests are forwarded to the subsystem processes that manage the HP TCP/IP
resources for which the TCP/IP Subagent is responsible. When the TCP/IP
Subagent receives a response, it uses the contents to update the values for MIB-II
cache objects.
•
The SNMP agent sends response messages to the SNMP manager from which
the request originated.
Note.
The TCP/IP Subagent performs no further authentication of SNMP requests
forwarded to it by the SNMP agent.
