Router configuration Router Router’s Functions : 1- IP addressing . 2- Routing . Components : 1- Hardware : · Interfaces . · DRAM: running configuration . · NVRAM : start up configuration . · CPU . · PCMCIA ( flash memory ) . 2- Software ( IOS ) . Router configuration modes : 1- User mode ( router> ). 2- Privilege mode ( router # ). 3- Global configuration ( router (config)#) . Dr.Faisal Alzyoud

Now we are in the user mode : To know the commands in user mode we use (?) : Dr.Faisal Alzyoud

To enter the privilege mode we use ( enable ) : Dr.Faisal Alzyoud To enter the privilege mode we use ( enable ) :

To see the commands in privilege mode we use (?) : Dr.Faisal Alzyoud

To manage the system clock we use ( clock ) : Dr.Faisal Alzyoud

To see the time we use ( show clock ) : Dr.Faisal Alzyoud

To see what inside DRAM: running configuration we use ( show ) : Dr.Faisal Alzyoud

To see what inside NVRAM : start up configuration we use ( show ) : Dr.Faisal Alzyoud

To see content of flash memory we use ( show ) : Dr.Faisal Alzyoud

To go to global configuration we use ( conf t ) : Passwords : Dr.Faisal Alzyoud Passwords : 1- Lone console password to protect the user mode :

2- Enable password to protect the privilage mode : Dr.Faisal Alzyoud 3- Secret password for more protection of privilage mode ( more priority than enable pass and it's encrypted pass .

Now we try the passwords set : Dr.Faisal Alzyoud We notice that only secret pass is encrypted :

To save the configuration we did in the NVRAM we use (wr or copy commands) Dr.Faisal Alzyoud

To restart we use the command (reload) : Dr.Faisal Alzyoud
