vlan下配置的acl失效原因

```
锐捷：接口acl  vlan下acl  全局acl

故障现象：vlan下配置的acl失效

配置的acl规则
ip access-list extended deny_by_8
 20 permit ip host 192.168.8.22 192.168.10.0 0.0.0.255
 60 permit ip 192.168.8.0 0.0.0.255 host 192.168.20.18
 90 permit tcp 192.168.8.0 0.0.0.255 192.168.9.0 0.0.0.255 eq 9999
 1001 deny ip 192.168.8.0 0.0.0.255 192.168.0.0 0.0.255.255
 1002 deny ip 192.168.8.0 0.0.0.255 172.16.0.0 0.15.255.255
 1003 deny ip 192.168.8.0 0.0.0.255 10.0.0.0 0.255.255.255
 
 vlan接口下引用acl
 !
interface VLAN 8
 description onesec
 ip access-group deny_by_8 in
 ip address 192.168.8.10 255.255.255.0
!
 
查看到的原因，是接口下遗留名为jishu的历史acl，删掉就好了
