Getting Started with HP-UX IPQoS

System Operation

If this is the first time you are starting HP-UX IPQoS after an initial install the expected state is ENABLED BUT NOT FILTERING.

If this starting of HP-UX IPQoS follows a previous stopping of HP-UX IPQoS without a reboot, the state is restored to whatever it was when HP-UX IPQoS was stopped (that is either ENABLED but NOT FILTERING or ENABLED and FILTERING).

If this is after an update or re-installation, HP-UX IPQoS uses the standard HP-UX “newconfig” method of preserving the original files by not overwriting them, but rather by creating files under “newconfig” directories for new information. Thus, the HP-UX IPQoS /opt/ipqos/db/ipqosdb.db (the active configuration database) and the /etc/rc.config.d/ipqos files remain unchanged. New information is placed into /usr/newconfig/opt/ipqos/db/ipqosdb.db and /usr/newconfig/etc/rc.config.d/ipqos respectively.

Stopping HP-UX IPQoS - Without a Reboot

This section describes how to stop HP-UX IPQoS without rebooting the system.

Scenarios where you may want to do this include the following:

You do not want to reboot the system and:

you are updating the software, on a system already running HP-UX IPQoS and you first must stop HP-UX IPQoS before you can install the update software.

you want to completely stop (isolate) HP-UX IPQoS, including remove the Packet Capturing module from your networking stack.

you want to remove HP-UX IPQoS (using swremove) and you must first completely stop (isolate) HP-UX IPQoS.

To stop HP-UX IPQoS without needing to reboot, perform the following steps:

CAUTION You must have experience manually configuring HP-UX networks to use this procedure.

Step 1. Run the following command:

#/sbin/init.d/ipqos stop

Step 2. Stop the current networking configuration using ifconfig to down and unplumb all the IPv4 and IPv6 interfaces. First down any secondary interfaces, then down the primary interfaces. Then unplumb the interfaces.
