This section provides information about relevant HP-UX IPQoS operating states including the state after initial boot and the state after reboots. It also describes how to start and stop HP-UX IPQoS without needing to reboot the system.
HP-UX IPQoS Operating States
HP-UX IPQoS operates in one of three possible states. Table 3-1 lists these states.
Table 3-1 | HP-UX IPQoS Operating States |

State During Normal Operations
During normal operation, HP-UX IPQoS is typically in the ENABLED and FILTERING state (when you have a configuration loaded) or possibly in the ENABLED but NOT FILTERING state (when you do not have a configuration loaded). In rare cases, you may want HP-UX IPQoS to be put into the DISABLED state or to be changed to an ENABLED state from the DISABLED state. See “Administering HP-UX IPQoS Operating States” on page 83, for information about how to change HP-UX IPQoS operating states.
State at Initial Boot after Installation
By default, HP-UX IPQoS comes up in the ENABLED but NOT FILTERING state during the initial system boot process. This is a result of the start-up parameter IPQOS in the /etc/rc.config.d/ipqos file being set to 1 by default. When IPQOS=1 HP-UX IPQoS is automatically enabled at boot time. (When IPQOS=0, HP-UX IPQoS comes up in the DISABLED state.)
