现场在int valn 口下下发包过滤，测试发现未生效

interface Vlan-interface1400

 description JRJG

 packet-filter name JRJG inbound

排查发现底层包过滤都有正常下发：

继续排查流量进来的物理口，发现物理口也有下发包过滤：

interface GigabitEthernet1/0/28

 port link-mode bridge

 description to_HF-CB-17F-S1_XGE1/0/49

 port link-type trunk

 undo port trunk permit vlan 1

 port trunk permit vlan 2 to 4094

 packet-filter name deny-CO_To_CB inbound // 物理端口也有下发，而且对应的acl，最后一条配置为permit ip 放通所有，而 物理口下的包过滤优先级高于int vlan 口，所以int vlan 口下的包过滤无法生效

 mirroring-group 1 mirroring-port both

调整物理接口下的包过滤后，测试正常生效
