回退配置：
[edit]
[email protected]# set chassis alarm sonet pll red
[edit]
[email protected]# show chassis alarm sonet
pll red;

[email protected]# rollback

配置文件存放位置：
root@junos1% cd /config/
root@junos1% ls
.snap juniper.conf.2.gz juniper.conf.gz
juniper.conf.1.gz juniper.conf.3.gz juniper.conf.md5
root@junos1% pwd
/config
root@junos1%
這是前3個配置文件所在位置
其他的在如下目錄中：
root@junos1% cd /var/db/config/
root@junos1% ls
juniper.conf.4.gz juniper.conf.6.gz
juniper.conf.5.gz juniper.conf.7.gz
root@junos1% pwd
/var/db/config
root@junos1%
rollback原則是：當前保存的配置文件是0，然後配置其他再度保存後前一次保存的配置文件由0變成1而剛剛保存的配置則是0以此類推，所以可以通過rollback+配置文件編號來實現各種回退
注：文件編號的範圍是0-49
保存配置文件到其他機器上：
以下例子是SSH
[email protected]# save [email protected]:/var/tmp/1
The authenticity of host '10.13.114.158 (10.13.114.158)' can't be established.
RSA key fingerprint is 51:55:8a:aa:64:9f:91:24:32:31:a1:92:80:90:bc:59.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '10.13.114.158' (RSA) to the list of known hosts.

也可以FTP TFTP等配置。
[edit]
[email protected]# save terminal \\等同於IOS的show run
加載配置文件到路由器上：
1.合併配置：
原有配置
[edit]
[email protected]# show chassis alarm sonet
lol yellow;
pll red;
加載配置
chassis {
alarm {
sonet {
pll red;
}
}
}
採用合併加載以後
[email protected]# load merge [email protected]:/var/tmp/1
[email protected]'s password:
1 100% 888 0.9KB/s 00:00
load complete
lol yellow依然存在
[edit]
[email protected]# show chassis alarm sonet
lol yellow;
pll red;
2.覆蓋加載：
而採用覆蓋加載
[edit]
[email protected]# load override [email protected]:/var/tmp/1
[email protected]'s password:
1 100% 888 0.9KB/s 00:00
load complete
發現lol yellow;不見了
[edit]
[email protected]# show chassis alarm sonet
pll red;
說明：合併是合併兩個配置將不同的覆蓋雙方沒有的合併，而覆蓋是不同的覆蓋自己沒有的刪除別人沒有的添加。
replace則是替換，也就是自己有的對方沒有的不改，對方有的自己沒有的也不改，只改自己有的對方也有的但是配置不同的部分。
運行：
[edit]
[email protected]# ping
^
unknown command.
想要直接運行ping是不成功的
需要這樣：
[email protected]# run ping 10.13.114.158

說明：JUNOS是運行在FREEBSD上的一個特殊的應用程序而已與cisco的IOS不同。
