Alcatel设备上的分类只能用其内部命名的8个,分别是:nc,h1,ef,h2,L1,af,l2,be,不能
更改这些命名,也不能定义其他转发类(sap端口可以定义转发子类,但不建议使用转发子类,因为network端口识别不了,配置会很复杂)。7750将
nc,h1,ef,h2四个FC作为高优先级考虑。L1,af,l2,be四个FC作为低优先级考虑。
转发的优先顺序如下(由高到低):
1.高优先级的Inprofile的包;
2.低优先级的Inprofile的包;
3.高优先级和低优先级的Outprofile的包。
注明:Inprofile,Outprofile是由每个FC映射的队列的CIR、PIR决定的。当流量速率小于或等于CIR的包标记上Inprofile;当流量速率大于CIR小于PIR的包标记上Outprofile;大于PIR的包丢弃。
1.1 配置队列调度
(1)网络口的分类和标记(网络口一般指设备的上联接口)

1.2 配置用户口的分类和标记(用户口是指接业务的逻辑端口)
注:每个sap的策略里都有一个queue1和queue11,这两个队列是自动创建的,queue1为单播队列,queue2为组播队列
(1)配置标记的策略,标记的是服务等级,而不是具体的数字
标记 服务等级
7 nc
6 h1
5 ef
4 h2
3 l1
2 af
1 l2
0 be
config qos
sap-ingress 111 create

exit
queue 11 multipoint create
exit
default-fc "l2"
exit
sap-ingress 122 create
description "sap_VIP_Remark"

exit

exit

exit
sap-ingress 133 create

exit

exit
sap-ingress 155 create
description "sap_NGN_Remark"
queue 1 create
exit
queue 11 multipoint create
exit
default-fc "ef"
exit
(2)将标记策略应用到sap端口上,例如接NGN的sap端口上
config service
vprnxxx
interface "GE1/2/9:20"
sap 1/2/9:20
ingress
qos 155
exit
1.3 配置网络口的出队列调度
(1)配置策略
config qos
network-queue "NetworkEgressQ"create
queue 1 create
rate 100 cir 18
mbs 50
cbs 1
high-prio-only 10
exit
queue 2 best-effort create
rate 100 cir 5
high-prio-only 10
exit
queue 3 best-effort create
rate 100 cir 15
high-prio-only 10
exit
queue 4 best-effort create
rate 100 cir 30
high-prio-only 10
exit
queue 5 expedite create
rate 100 cir 20
high-prio-only 10
exit
queue 6 expedite create
rate 10 cir 10
high-prio-only 10
exitqueue 7 expedite create
rate 2 cir 2
high-prio-only 10
exit
fc af create
multicast-queue 9
queue 3
exit
fc be create
multicast-queue 9
queue 1
exit
fc ef create
multicast-queue 9
queue 6
exit
fc h2 create
multicast-queue 9
queue 5
exit
fc l1 create
multicast-queue 9
queue 4
exit
fc l2 create
multicast-queue 9
queue 2
exit
exit
(2)将策略应用到上行口的出方向
port 1/2/1
ethernet
network
queue-policy "NetworkEgressQ"
exit
exit
exit
