Cisco 7206 router with ATM interface

7206 with ATM cards

General router config

Lets set a password and a hostname. Without a password, the router will not allow any network based access. This sets up a password on telnet (vty) and the console serial port (con). Additionally and enable secret is set to allow higher level of access for configuration.

Router(config-line)# line con 0
Router(config-line)# password yourpassword
Router(config-line)# login

Router(config-line)# line aux 0
Router(config-line)# line vty 0 4
Router(config-line)# password yourpassword
Router(config-line)# login
Router(config-line)# exit
!
Router(config)#enable secret 5 yourenablepw

! encrypt saved passwords
Router(config)#service password-encryption
!
Router(config)#hostname cisco7206
cisco7206(config)#

Lets set NTP to synchronise time, this sets the running system clock but does not affect the hardware clock.

cisco7206(config)#ntp clock-period 17175169
cisco7206(config)#ntp server 192.168.1.1  
cisco7206(config)#exit
cisco7206#

discuss show cal and setting ntp to cal.

7200 router has nvram for storing startup configs etc. and flash memory for storing IOS images. Also there are two PCMCIA slots which can use flash modules FIXME.

ATM

Test circuit on the Cisco router.

For the purposes of this exercise, the router will have IP address 192.168.0.1 and the linux machine will have the IP address 192.168.0.2.
