20.4 Egress QoS Examples
 Not all equipments support Egress QoS presently, so please make sure the current device supports
this function.
 If the policy configured cannot bind to the port or VLAN, please check whether the match option in
classification table is supported by the current device.
 If terminal printing suggests lack of resource, please make sure there is enough resource to send the
current policy.
 If the policy with match acl configured cannot bind to the port or VLAN, please make sure rules
including permit exist in ACL.
 If modifying QoS attribute is invalid by Egress QoS remark, please ensure whether ingress sets the
correspondsing QoS attribute with trust.
 If egress set QoS attributes (set cos/ip dscp) for modifying all packets, and it uses Egress remark to
modify QoS attributes for packets of different colors, previous modification is preferential for modifying
packets.
