Port Speed Change - Cisco ASR 9000 Series Configuration Manual

QoS Policy Inconsistency on an Interface: Example
Bandwidth: 0 kbps, BW sum for Level 1: 200000 kbps, Excess Ratio: 1
----------------------------------------------------------------------
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.
If the ANCP rate has been configured to a value less than the shape rate, the inconsistency is not
Note
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.

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
