JUNOS的基本操作
重启：
[email protected]> request system reboot ?
Possible completions:
<[Enter]> Execute this command
at Time at which to perform the operation
in Number of minutes to delay before operation
media Boot media for next boot
message Message to display to all users
| Pipe through a command
关机：
[email protected]> request system power-off
或
[email protected]> request system halt
日志查看：
[email protected]> show log messages | match fail
保存配置：
[edit]
[email protected]# commit
commit complete
[edit]
回退配置：
[edit]
[email protected]# set chassis alarm sonet pll red
[edit]
[email protected]# show chassis alarm sonet
pll red;
[edit]
[email protected]# rollback
load complete
[edit]
[email protected]# show chassis alarm sonet
[edit]
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%
这是前3个配置文件所在位置
其他的在如下目录中：
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原则是：当前保存的配置文件是0，然后配置其他再度保存后前一次保存的配置文件由0变成1而刚刚保存的配置则是0以此类推，所以可以通过rollback+配置文件编号来实现各种回退
注：文件编号的范围是0-49
保存配置文件到其他机器上：
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.
[email protected]'s password:
tempfile 100% 888 0.9KB/s 00:00
Wrote 49 lines of configuration to '[email protected]:/var/tmp/1'
[edit]
也可以FTP TFTP等配置。
[edit]
[email protected]# save terminal \\等同于IOS的show run
加载配置文件到路由器上：
1.合并配置：
原有配置
[edit]
[email protected]# show chassis alarm sonet
lol yellow;
pll red;
加载配置
chassis {
alarm {
sonet {
pll red;
}
}
}
采用合并加载以后
[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.覆盖加载：
而采用覆盖加载
[edit]
[email protected]# load override [email protected]:/var/tmp/1
[email protected]'s password:
1 100% 888 0.9KB/s 00:00
load complete
发现lol yellow;不见了
[edit]
[email protected]# show chassis alarm sonet
pll red;
说明：合并是合并两个配置将不同的覆盖双方没有的合并，而覆盖是不同的覆盖自己没有的删除别人没有的添加。
replace则是替换，也就是自己有的对方没有的不改，对方有的自己没有的也不改，只改自己有的对方也有的但是配置不同的部分。
运行：
[edit]
[email protected]# ping
^
unknown command.
想要直接运行ping是不成功的
需要这样：
[email protected]# run ping 10.13.114.158
PING 10.13.114.158 (10.13.114.158): 56 data bytes

64 bytes from 10.13.114.158: icmp_seq=1 ttl=64 time=0.428 ms
^C

说明：JUNOS是运行在FREEBSD上的一个特殊的应用程序而已与cisco的IOS不同。
