你好：

SDK的版本号为：04.02.00.09

内核版本号为：4.9.59

在/lib/systemd/network下设置静态IP地址，如下：

[Match]
Name=eth0

[Network]
Address=10.163.248.6/24
Broadcast=10.163.248.255
Netmask=255.255.0.0
Gateway=10.163.248.1

发现修改子网掩码Netmask不起作用，只有修改IP地址以后的数字（/24）才起作用，我怎么操作只修改Netmask才能让子网掩码生效？

请问使用的是自己的板子吗？您的意思只有IP地址改成0.163.248.24，Netmask才能生效？

能否发一下Log信息？

把子网掩码设置成255.255.0.0，在网口看还是255.255.255.0.

抱歉回复晚了，请看下面e2e工程师的回复。

Apologies for the delayed response. Do you still need assistance here? If so,

1) please help me understand what you are doing here. It looks like you are setting the netmask to a class B subnet, and then trying to change it to a class C subnet? Why?

2) Please show the process you are following to update the subnet

3) I assume this is CPSW Ethernet?

4) Please note that we can no longer support questions about kernel 4.9, since the last kernel 4.9 release was so many years ago. So the support we can offer here will be limited.
