{"Image DocumentName": "Advanced QoS Interface Groups", "Image ImageDescription": "Interface groups are used in the creation of role-based policies. Role-based policies differ from port-based policies in the fact that role-based policies group ports together to apply a common set of rules to them. Each port can belong to only one interface group. When you move a port to another interface group (role combination), the classification elements associated with the previous interface group are removed and the classifications elements associated with the new interface group are installed on the port. At factory default, ports are assigned to the default interface group (role combination), which is named allQoSPolicyIfcs. All ports must be removed from an interface group before it is deleted. An interface group cannot be deleted when it is referenced by a policy.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
