Every access Ethernet port is associated, by default, with the default access ingress policy (policy-id 1) when the access-ingress-qos mode command is set to port-mode. You can replace the default policy with a user-defined policy. If the non-default access ingress policy is removed, the association reverts to default policy-id 1. A QoS policy cannot be deleted until it is removed from all access ports where it is applied.
*A:card-1>config>qos# no access-ingress 30
MINOR: CLI Could not remove Access ingress policy "30" because it is in use.
The access-ingress-qos-mode command can only be changed to sap-mode if access ingress policy 1 is attached to the port.
