一般情况下使用show run命令
这个文件存储在flash中的system文件夹里
R3#dir system:
Directory of system:/
2 dr-x 0 <no date> memory
1 -rw- 516 <no date> running-config11 dr-x 0 <no date> vfiles
No space information available
也可以使用以下命令查看
R3#more system:/running-config
!
version 12.3
service timestamps debug datetime msec
R3#show star
可以查看保存后的配置文件，这个文件也叫启动配置文件
这个文件保存在nvram中
可以通过以下命令查看
R3#dir nvram:
Directory of nvram:/
30 -rw- 516 <no date> startup-config
31 ---- 5 <no date> private-config
1 -rw- 0 <no date> ifIndex-table
32762 bytes total (31167 bytes free)
这个文件是否被调用是基于寄存器的值来确定的，可以通过show ver命令来查看
R3#show version
