Provides the means for performing a network dump.

Syntax

Description

The tokdump entry point provides support for six of the seven dump commands. The DUMPWRITE command is not supported for network dump. The tokdumpwrt entry point supports this write function.

The supported commands are:

DUMPINIT	Initializes the token-ring device handler as a dump device.
DUMPQUERY	Gets the information required for performing a network dump. The information is returned in the dmp_query structure in /usr/include/sys/dump.h file. It contains the following information: tokdumpwrt operation address Minimum data transfer size Maximum data transfer size
DUMPSTART	Starts the network dump processing.
DUMPREAD	Initiates a dump read request to the token-ring device handler.
DUMPEND	Terminates the network dump processing.
DUMPTERM	Terminates the token-ring device hander as a dump device.

The tokdump entry point functions with a Token-Ring High-Performance Network Adapter that has been correctly configured for use on a qualified network. Consult adapter specifications for more information on configuring the adapter and network qualifications.

Execution Environment

The DUMPINIT command can be called from the process environment only. DUMPQUERY, DUMPSTART, DUMPREAD, DUMPEND, and DUMPTERM commands can be called in both the process environment and the interrupt environment.
