예:
class-map match-any realtime
class-map match-any priority
class-map match-any missioncritical
class-map match-any transactional
class-map match-any scavenger
또는
policy-map Edge-QoS
class realtime
class priority
class missioncritical

제한:
해결 방법:
예:
int range Gi1/0/1 - 24
service-policy input queueing
% Range command terminated because it failed on GigabitEthernet1/0/1
제한:없음
해결 방법:
예:
access-list 150 permit ip 172.16.2.0 0.0.0.255 172.16.1.0 0.0.0.255
class-map match-any SAN_TRAFFIC
match access-group 150
!
policy-map SAN_POLICY
class SAN_TRAFFIC
bandwidth remaining ratio 10
class class-default
shape average percent 10
제한:오류 메시지와 동일
해결 방법:
- DSCP/CoS/IPP/QoS 그룹 표시를 ACL과 일치하는 인그레스 트래픽으로 설정하려면 입력 정책을 생성합니다. 또는
- 큐잉 대신 정책 속도 기능을 사용합니다.

해결 방법:
예:
3850(config-if)#auto qos voip trust
% Cannot be deleted. Tablemap being used in policy maps.
AutoQoS Error while generating commands on Gi1/0/3.
