Junos 11.2 平台上面开启引入protect这个小feature，下面我们来看看如何使用

SRX中，我们通常会单独拿一个接口出来做网管接口，并且划入到管理zone中。
set interfaces ge-0/0/0 unit 0 family inet address 192.168.102.75/24set security zones functional-zone management interfaces ge-0/0/0.0set security zones functional-zone management host-inbound-traffic system-services telnetset security zones functional-zone management host-inbound-traffic system-services httpsset security zones functional-zone management description "OOB Management Interface"

为了防止误操作，删除网管接口或者网管zone，我们可以将配置保护起来。
protect interfaces ge-0/0/0protect security zones functional-zone management

我们试着删除接口配置，发现删除不了。

itaa@SRX240# delete interfaces ge-0/0/0
warning: [interfaces ge-0/0/0] is protected, 'interfaces ge-0/0/0' cannot be deleted

如果操作一下，会把除了网管接口之外的其他接口配置删除

itaa@SRX240# delete interfaces
warning: [interfaces ge-0/0/0] is protected, 'interfaces ge-0/0/0' cannot be deleted

一起学习~！
