Table 1–1 (Cont.) SNMP Component Files

File	Location	Function
TCPIP$SNMP_TRAPRCV.EXE	SYS$SYSTEM	Utility for receiving trap
		messages.
TCPIP$ESNMP_SHR.EXE	SYS$SHARE	Image file containing eSNMP
		application programming
		interface (API) routines.
TCPIP$SNMP_STARTUP.COM	SYS$STARTUP	Command procedure
		that installs master and
		subagent images and runs
		TCPIP$SNMP_RUN.COM.
TCPIP$SNMP_SYSTARTUP.COM	SYS$STARTUP	Command procedure
		initiated by TCPIP$SNMP_
		STARTUP.COM. Provided for
		site-specific customizations,
		such as parameter settings.
TCPIP$SNMP_RUN.COM	TCPIP$SYSTEM	Command procedure that
		starts the master agent and
		subagents.

		stops the master agent and
		subagents.
TCPIP$SNMP_SYSHUTDOWN.COM	SYS$STARTUP	Command procedure
		initiated by TCPIP$SNMP_
		SHUTDOWN.COM.
		Provided for site-specific
		customization, such as
		parameter settings.
TCPIP$EXTENSION_MIB_STARTUP.COM SYS$SYSDEVICE:[TCPIP$SNMP]
		Command procedure
		invoked by TCPIP$SNMP_
		SYSTARTUP.COM to start
		custom subagents.
TCPIP$EXTENSION_MIB_	SYS$SYSDEVICE:[TCPIP$SNMP]
SHUTDOWN.COM
		Command procedure
		invoked by TCPIP$SNMP_
		SYSHUTDOWN.COM to
		stop custom subagents.
TCPIP$EXTENSION_MIB_RUN.COM	SYS$SYSDEVICE:[TCPIP$SNMP]
		Command procedure
		invoked by TCPIP$SNMP_

SYSTARTUP.COM when the service is enabled and starts detached processes to run subagents.

1.4 Writing an eSNMP Subagent

Table 1–2 lists the files that are available to help you develop MIBs and subagents. Except where noted, the files are located in the directory pointed to by
