In-Place Policy Modification
The In-Place Policy Modification feature allows you to modify a QoS policy even when the QoS policy is
attached to one or more interfaces. When you modify the QoS policy attached to one or more interfaces, the
QoS policy is automatically modified on all the interfaces to which the QoS policy is attached. A modified
policy is subject to the same checks that a new policy is subject to when it is bound to an interface.
If the policy-modification is successful, the modified policy takes effect on all the interfaces to which the
policy is attached. The configuration session is blocked until the policy modification is complete.
However, if the policy modification fails on any one of the interfaces, an automatic rollback is initiated to
ensure that the pre-modification policy is in effect on all the interfaces. The configuration session is blocked
until the rollback is complete on all affected interfaces.
If unrecoverable errors occur during in-place policy modification, the policy is put into an inconsistent state
on target interfaces. Use the show qos inconsistency command to view inconsistency in each location. (This
