Router configuration Components : 1 - Hardware : · Interfaces. · DRAM: running configuration. · NVRAM : start up configuration. · CPU. · PCMCIA ( flash memory ). 2 - Software ( IOS ). Dr. Faisal Alzyoud Router’s Functions : 1 - IP addressing. 2 - Routing. Router configuration modes : 1 - User mode ( router> ). 2 - Privilege mode ( router # ). 3 - Global configuration ( router (config)#). 1
Dr. Faisal Alzyoud • Now we are in the user mode : • To know the commands in user mode we use (? ) : 2
Dr. Faisal Alzyoud To enter the privilege mode we use ( enable ) : 3
Dr. Faisal Alzyoud To see the commands in privilege mode we use (? ) : 4
Dr. Faisal Alzyoud 5 To manage the system clock we use ( clock ) :
Dr. Faisal Alzyoud 6 To see the time we use ( show clock ) :
Dr. Faisal Alzyoud To see what inside DRAM: running configuration we use ( show ) : 7
Dr. Faisal Alzyoud 8 To see what inside NVRAM : start up configuration we use ( show ) :
Dr. Faisal Alzyoud To see content of flash memory we use ( show ) : 9
Dr. Faisal Alzyoud To go to global configuration we use ( conf t ) : Passwords : 10 Passwords : 1 - Lone console password to protect the user mode :
Dr. Faisal Alzyoud 2 - Enable password to protect the privilage mode : 3 - Secret password for more protection of privilage mode ( more priority than enable pass and it's encrypted pass. 11
Dr. Faisal Alzyoud • Now we try the passwords set : We notice that only secret pass is encrypted : 12
Dr. Faisal Alzyoud To save the configuration we did in the NVRAM we use (wr or copy commands) 13
Dr. Faisal Alzyoud • To restart we use the command (reload) : 14
