SR8808-X qos policy 添加preorder后匹配不到流量

现场接口下发qos policy xx preorder ，对匹配的流量做重定向操作。具体配置如下，下发后发现流量未按qos配置转发，但是将qos策略的preorder删去后，流量就能正常重定向。

接口配置：

#

interface GigabitEthernet5/1/15

port link-mode route

ip address 109.1.1.1 255.255.255.0

qos apply policy 1 inbound preorder 1

 qos apply policy test1 inbound

#

traffic classifier 1 operator and

if-match acl 3888

#

traffic behavior 1

redirect next-hop 24.1.1.1

#

qos policy 1

classifier 1 behavior 1

#

traffic classifier test1 operator and

if-match acl 3999

#

traffic behavior test1

redirect next-hop 100.120.130.1

#

qos policy test1

classifier test1 behavior test1

看接口的qos策略下发情况，发现preorder1的qos策略下发失败。所以重定向未生效。

经确认，preorder1能提供qos优先级，但是高优先级的qos policy中的动作不支持重定向，remark，以及CBQ(即queue xx)。
