tokdump Token-Ring Device Handler Entry Point


Provides the means for performing a network dump.


Refer to the dddump entry point for the complete syntax of the dump entry point.


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.

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.

Implementation Specifics

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.
