Administering HP-UX IPQoS Operating States
Administering HP-UX IPQoS Operating States
HP-UX IPQoS has three operating states:
•DISABLED
•ENABLED but NOT FILTERING
•ENABLED and FILTERING
During normal operations HP-UX IPQoS is typically in one of the two ENABLED states. In rare cases, you may want HP-UX IPQoS to be put in the DISABLED state or to be changed to an ENABLED state from the DISABLED state. This section explains how to administer HP-UX IPQoS operating states for both the more and less common scenarios.
Using ipqosadmin to Change States
HP-UX IPQoS is in the ENABLED but NOT FILTERING state, until the first configuration is successfully loaded. Once this occurs, HP-UX IPQoS is in the ENABLED and FILTERING state.
The active configuration does not need to be unloaded before loading a new configuration file.
When a new configuration file is loaded, it replaces the existing configuration file, The state remains ENABLED and FILTERING. Thus, typically HP-UX IPQoS remains in the ENABLED and FILTERING state for as long as you are using active configurations.
If you want to unload the active configuration, and thus effectively run with no HP-UX IPQoS configuration controls, run the following command:
#ipqosadmin -unload
This puts HP-UX IPQoS into the ENABLED but NOT FILTERING state.
If you decide you want to load a configuration file, run the following command:
#ipqosadmin -load -f filename -verbose
This puts HP-UX IPQoS (assuming the load was successful) into the ENABLED and FILTERING state.
The only ipqosadmin options that can affect the state of HP-UX IPQoS are -loadand
-unload. The -stateoption displays the state, but cannot change the state. The other options (-verify, -showconfig, -showstatsand -loglevel) have no effect on the operating state.
The -loadand -unloadeffects on the state of HP-UX IPQoS can be summarized as follows:
