Cisco 6509 QOS配置
1. 分类：
class-map match-any dscp32
match ip dscp 32
class-map match-any dscp48
match ip dscp 48
class-map match-any dscp8-26
match ip dscp 8 16 24
class-map match-any dscp40-56
match ip dscp 40 56
class-map match-any dscp0
match ip dscp 0
2. 定义队列及调度
policy-map my-qos
class dscp32
priority percent 20
class dscp48
bandwidth percent 5
random-detect
random-detect precedence 6 1498 9690 1
class dscp40-56
bandwidth percent 25
random-detect
random-detect precedence 6 1498 9690 1
class dscp8-26
bandwidth percent 20
random-detect
random-detect precedence 6 1498 9690 1
class dscp0
bandwidth percent 29
random-detect
random-detect precedence 6 1498 9690 1
3. 二层端口应用QoS
interface GigabitEthernetx/x
wrr-queue bandwidth 30 70
wrr-queue cos-map 1 1 6
wrr-queue cos-map 1 2 5 7
wrr-queue cos-map 2 1 1 2 3
wrr-queue cos-map 2 2 0
priority-queue cos-map 1 4
rcv-queue cos-map 1 3 6
4. 三层端口应用QoS
interface Gx/x 或 Vlan xx
service-policy output my-qos
