B.2 SNAplus2 APPN SNMP Subagent
SNAplus2 implements an SNMP subagent to provide support for the APPN MIB defined in RFC 1593. The subagent
uses the services of the SNMPD daemon, which communicates with a management application using TCP/IP. The
subagent supports receiving SNMP Get requests for a subset of the objects contained in the APPN MIB.
The subagent does not support every object in the APPN MIB. Specifically, the APPN SNMP subagent does not
support receiving SNMP Set requests or sending traps to the SNMP manager. A list of supported objects is included
in Section B.3,
APPN Management Information Base (MIB).
The subagent requires that the SNMPD subsystem be configured and started in order to support APPN network
management requests. The subagent, when started, registers the objects it supports with the SNMPD daemon. If
SNMPD is not already running when the subagent is started, the subagent polls for SNMPD. When the subagent
detects that SNMPD has been started, it registers its objects with SNMPD. The SNMPD daemon is normally started
automatically by the operating system.
In a correctly configured system, the following processes should be running:
snasnmp and the SNMPD daemon.
The SNMPD subsystem uses TCP/IP as the network protocol for transporting SNMP requests to and from the
management application.
The SNMP subagent is automatically installed and configured when you install SNAplus2.
B.3 APPN Management Information Base (MIB)
The APPN MIB is defined by informational RFC 1593. The ASN.1 representation of the APPN MIB is located in
the file named /etc/opt/sna/mib/appn.my, which also provides a more detailed description of the APPN
MIB objects. This MIB definition should be used with your management application.
The SNAplus2 SNMP subagent supports all of the APPN MIB except for the following objects:
• APPN generic DLC trace table (ibmappnNodePortDlcTraceTable)
• TCP/IP specific link station table (ibmappnNodeLslpTable)
• Link error status table (ibmappnNodeLsStatusTable)
