Introducing SNAplus2

Beneﬁts Provided by SNAplus2

SNMP-MIB, which is adapted for APPN networks from

TCP/IP, is a distributed management service based on

an agent-manager architecture. This management

scheme uses several components: one or more SNMP

agents, a manager, and a MIB database, all of which

typically reside on different nodes. The manager and

agent communicate with each other by using the

SNMP protocol.

• An SNMP agent is a process that runs on and

monitors the status of the system being managed.

The agent maintains a MIB database for that

system.

• The manager (an application) queries the agent for

MIB information and processes the response. The

manager can also receive unsolicited data (SNMP

traps) from the agent.

• APPN network managers can use APPN

SNMP-MIB to gather information to analyze the

network and correct problems. SNAplus2 uses

agent software that supports the APPN MIB. For

more information about the APPN MIB, refer to

HP-UX SNAplus2 Administration Guide.

Service point command facility (SPCF)

A NetView operator can use SPCF to issue SNAplus2

conﬁguration and administration commands from the

NetView terminal, to control the SNAplus2 node

remotely.

UNIX command facility (UCF)

A NetView operator can use UCF to issue HP-UX

commands on the SNAplus2 computer from the

NetView terminal.
