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）

#*/策略：ingress方向信任EXP，DSCP标记；egress方向重新标记*/

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

exit

exit
sap-ingress 122 create

exit

exit

exit
sap-ingress 155 create
description "sap_NGN_Remark"
queue 1 create
exit
queue 11 multipoint create
exit

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
