Once the ANCP rate returns to the configured value, the inconsistency is automatically cleared, which
can be confirmed by issuing the show qos interface command.
Note If the ANCP rate has been configured to a value less than the shape rate, the inconsistency is not
automatically cleared, and the policy must be modified and reapplied. To prevent this from occurring,
be sure to configure the policy-map shape rate to the minimum value of all ANCP rates for a given
service level.
Port Speed Change
If the port speed is configured to less than the QoS parent shaper rate for example to 100 Mbps (100000
kbps), the requirement is no longer met since the port speed is no longer greater than the QoS parent
shaper rate of 800000 kbps.

LC/0/0/CPU0:Nov 4 05:36:55.041 : qos_ma_ea[197]: %QOS-QOS_EA_MODIFY_FAIL-3-ERROR :
inconsistency detected due to ANCP or Bandwidth modification. Execute show qos
inconsistency, to obtain information. Policy resolution failure
RP/0/RSP0/CPU0:ro-node1(config-if)#end
This causes the QoS policy on the interface to be placed in the inconsistency state as shown by the
following show qos interface command output:
RP/0/RSP0/CPU0:ro-node1#sh qos int gigabitEthernet 0/0/0/1.1 output
Interface: GigabitEthernet0_0_0_1.1 output Bandwidth: 1000000 kbps ANCP: 0 kbps
