S6805接口区分ipv4和ipv6流量大小

在接口下开启 statistics l3-packet enable 后，通过display interface 下的IPv4 traffic statistics和IPv6 traffic statistics 读取。但是接口报文流量过大时，开启statistics l3-packet enable功能会造成设备CPU占用率高，影响转发性能。

因此，当用户不需要单独统计接口接收的IPv6报文数量时，不建议开启这个功能。

另外在开启了statistics l3-packet enable可以通过如下节点读取route接口的ipv4和ipv6 统计数目。

ipIfStatsInReceives (1.3.6.1.2.1.4.31.3.1.3)

ipIfStatsOutTransmits (1.3.6.1.2.1.4.31.3.1.30)

hh3cifPortProtocolStatTable（1.3.6.1.4.1.25506.8.35.5.1.13）下的节点可以读取到二层ip报文数目(pkts)和字节数(octets) 

eg:

可分别读取ipv4/ipv6的报文，比如如下的1.195的 1 表示ipv4，2.195的 2 表示ipv6，195（端口的index）可在dis system internal ifmgr list中查询或者通过读取接口和索引对应关系的OID来读取。

【使用指导】

开启本功能后，设备会统计接口接收或发送的IPv6报文的数量，该统计信息可通过display interface命令查看。接口报文流量过大时，开启本功能会造成设备CPU占用率高，影响转发性能。因此，当用户不需要统计接口接收的IPv6报文数量时，建议关闭本功能。
