Quality of Service 473
Only a single mode can be active at a time. When the system is configured to
work in QoS Advanced mode, settings for QoS Basic mode are not active and
vice versa.
When the QoS mode is changed, the following occurs:
• When changing from Advanced mode to any other mode, policy profile
definitions and class maps are deleted. ACLs, which are bonded directly to
interfaces, remain bonded.
• When changing from Basic mode to Advanced mode, the QoS Trust mode
configuration in Basic mode is not retained.
• When disabling QoS, the shaper and queue setting (WRR/SP bandwidth
settings) are reset to default values.
All other user configurations remain intact.
