某局点 S12508F-AF 流策略下发失败

1. 配置限制和指导

当ACL用于QoS策略的流分类或用于报文过滤功能时：

·     若报文过滤功能应用于出方向，规则不支持配置vpn-instance参数。

·     若QoS策略或报文过滤功能应用于出方向：

¡     对于上送CPU后的报文、进行二层转发的报文和进行三层转发的报文，IPv4基本ACL规则rule [ rule-id ] { deny | permit } { object-group address-group-name | source { source-address source-wildcard | any } | vpn-instance vpn-instance-name }仅支持匹配进行三层转发的报文。

2.      Bagg1应用的qos filter的第三个cb对中acl 3012下发了rule 5 deny ip，这条规则在底层会下发三条deny规则，一条用于deny ipv4_uc、即ipv4单播流量，一条deny ipv4_mc、即ipv4组播，一条ipv4_any、即任意ipv4流量；bagg1上来二层互访的39.136.10.X的流量，能够匹配上ipv4_any这一条，然后被deny掉，因此二层流量不通；

3.      Vlan-int下应用packet-filter acl 3011，最后有一条deny ip，这个deny在底层只会下一条ipv4_uc的规则，这个规则只能用于匹配三层单播流量，因此匹配不上39.136.10.X网段的二层互访流量；但是包过滤缺省是放通的，因此在vlan-int下应用报过没有deny掉二层互访的业务；
