路由器 QOS限速及带宽保证配置

公司路由器WAN口上已经配有端口限速，限制公司所有IP上下行速度最大为5M，现在想对公司一些特殊IP地址的流量优先转发，请问这样做是否可行（即同一接口下，是否可以同时配置限速和带宽保证），实施后，如何来验证带宽保证是否生效。

公司路由器上的限速配置：

qos carl 1 source-ip-address range 172.16.20.1 to 172.16.20.255 per-address

 qos carl 2 source-ip-address range 172.16.30.1 to 172.16.30.255 per-address

 qos carl 3 destination-ip-address range 172.16.20.1 to 172.16.20.255 per-address

 qos carl 4 destination-ip-address range 172.16.30.1 to 172.16.30.255 per-address

interface GigabitEthernet1/0/2

 qos car outbound carl 1 cir 5000 cbs 312500 ebs 0 green pass red discard yellow pass

 qos car outbound carl 2 cir 5000 cbs 312500 ebs 0 green pass red discard yellow pass

 qos car inbound carl 3 cir 5000 cbs 312500 ebs 0 green pass red discard yellow pass

 qos car inbound carl 4 cir 5000 cbs 312500 ebs 0 green pass red discard yellow pass

需要新加的流量优先转发的配置：

acl number 2000

 rule 0 permit source 172.16.20.100 0.0.0.0

acl number 2001

  rule 0 permit source 172.16.30.100 0.0.0.0

acl number 2002

  rule 0 permit source any 

qos pql test protocol ip acl 2000 queue top

qos pql test protocol ip acl 2001 queue top

qos pql test protocol ip acl 2002 queue tottom

interface GigabitEthernet1/0/2

  qos pq pql test
