Configuring Auto-QoS on a Standalone Supervisor Engine 6-E/6L-E or Supervisor Engine 7-E/7L-E/8-E
The previous section listing defines the AutoQoS macros for defining QoS guidelines prior to Solution
Note
Reference Network Design 4.0 (SRND4). Starting with Cisco Release XE 3.3.0(SG) and 15.1(1)SG, the
Catalyst 4500 series switch supports the auto qos srnd4 command.
The following classes are required and generated by all SRND4 CLIs.
class-map match-all AutoQos-4.0-Priority-Queue
class-map match-all AutoQos-4.0-Control-Mgmt-Queue
class-map match-all AutoQos-4.0-Multimedia-Conf-Queue
class-map match-all AutoQos-4.0-Multimedia-Stream-Queue
class-map match-all AutoQos-4.0-Trans-Data-Queue
class-map match-all AutoQos-4.0-Bulk-Data-Queue
class-map match-any AutoQos-4.0-Scavenger-Queue
The output policy maps are as follows:
! Each class maps to a different qos-group with
! class-default taking any traffic not assigned to a qos-group
! Note: in this example, the outbound policy map drops voice packets when the priority
queue exceeds 33% utilization of the link. Each deployment must establish their own upper
bound for voice packets.
