请教一个关于MPLS QoS的问题

k8l3n6

在路由器7600上，设置了如下的class-map和policy-map<br /><br />class-map match-any EXP567<br /> match mpls experimental topmost 5<br /> match mpls experimental topmost 6<br /> match mpls experimental topmost 7<br /><br />class-map match-any EXP243<br /> match mpls experimental topmost 5<br /> match mpls experimental topmost 6<br /> match mpls experimental topmost 7<br /><br /> <br />policy-map POLICY<br /> Class EXP567<br />priority<br />police cir percent 10 conform-action transmit exceed-action set-mpls-exp-topmost-transmit 3 <br />violate-action set-mpls-exp-topmost-transmit 3<br /><br /> Class EXP234<br />bandwidth percent 60<br />queue-limit 2048<br />police cir percent 10 conform-action transmit exceed-action set-mpls-exp-topmost-transmit 3 <br />violate-action set-mpls-exp-topmost-transmit 3<br /><br />奇怪的是，当把如上的policy-map应用到接口时，会出现如下的错误提示：<br /><br />Router(config-if)#service-policy output POLICY<br />exceed action: set-mpls-exp-transmit cannot be configured for this interface<br />Configuration failed!<br /><br />下面是借口的配置，不知道问题出在哪里？<br /><br />interface GigabitEthernet3/0/0<br /> mtu 9000<br /> ip address 172.24.2.150 255.255.255.252<br /> ip ospf message-digest-key 200 md5 7 110B0C1C3742087425<br /> ip ospf network point-to-point<br /> ip ospf dead-interval minimal hello-multiplier 3<br /> load-interval 30<br /> speed nonegotiate<br /> mls qos trust cos<br /> mpls ip<br /> no clns route-cache<br />end<br /><br />我也曾试过，把topmost该成imposition，但是出现同样的错误，不知道有没有那位有类似的经历？如何解决的？
