— 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 -load fails, 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
