Chapter 44 Configuring Quality of Service
Configuring Auto-QoS on a Standalone Supervisor Engine 6-E/6L-E or Supervisor Engine 7-E/7L-E/8-E
Note
The previous section listing defines the AutoQoS macros for defining QoS guidelines prior to
Solution
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
match qos-group 32
class-map match-all AutoQos-4.0-Control-Mgmt-Queue
match qos-group 16
class-map match-all AutoQos-4.0-Multimedia-Conf-Queue
match qos-group 34
class-map match-all AutoQos-4.0-Multimedia-Stream-Queue
match qos-group 26
class-map match-all AutoQos-4.0-Trans-Data-Queue
match qos-group 18
class-map match-all AutoQos-4.0-Bulk-Data-Queue
match qos-group 10
class-map match-any AutoQos-4.0-Scavenger-Queue
match qos-group 8
match dscp cs1
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.
