juniper SRX 保存文档报错如下：
[edit interfaces ge-0/0/1 unit 0]
‘family’
When ethernet-switching family is configured on an interface, no other family type can be configured on the same interface.
error: configuration check-out failed
解决办法:
在配置三层接口的时候，要先删除二层接口：
edit interfaces ge-0/0/0 unit 0
delete family ethernet-switching
再去：commit
