Administering HP-UX IPQoS
Administering HP-UX IPQoS Operating States
—change state from ENABLED but NOT FILTERING to ENABLED and FILTERING
—or keep state in ENABLED and FILTERING (while replacing the active configuration with the newly loaded file)
(If -loadfails, state is not changed.)
•-unload can:
—change state from ENABLED and FILTERING to ENABLED but NOT FILTERING
(removing the active configuration)
—or keep state in ENABLED but NOT FILTERING (if there was not an active configuration to remove)
Disabling/Re-Enabling HP-UX IPQoS
For some scenarios you may want to disable HP-UX IPQoS. For example, as part of a troubleshooting effort. Or for example, in the case where you want to temporarily prohibit applications that create/modify HP-UX IPQoS configurations from being able to do so (since in some cases it is simpler to stop HP-UX IPQoS than to modify the application/scripts).
This section describes how to disable and re-enable HP-UX IPQoS.
Disable: To disable HP-UX IPQoS, run the following command:
#/sbin/init.d/ipqos stop
This accomplishes the following (assuming the command is successful):
—Puts HP-UX IPQoS in the DISABLED state.
—Only works ephemerally, will not propagate across reboots.
—Effectively (though not completely) disables HP-UX IPQoS.
Specifically, it isolates HP-UX IPQoS since it disables the HP-UX IPQoS Filtering module, however it does not remove the HP-UX IPQoS module that is part of the HP-UX networking STREAMS stack. For a brief description and graphical overview of the architecture of these modules, see “HP-UX IPQoS Architecture” on page 27.
If the command fails, examine the displayed error messages to determine the next steps.
Re-Enabling:If you had previously placed HP-UX IPQoS in the DISABLED state (by running /sbin/init.d/ipqos stop) and want to re-enable HP-UX IPQOS, run the following command:
#/sbin/init.d/ipqos start
