configuring cisco router 877

[alsolaih]

hi;

I've a cisco router 877 and I configured every thing by using copy from text file that I've already taken from another router.
there's one thing that I couldn't do it:
ppp chap 7 password xxxx
ppp pap sent-username xxxx password 7 xxxx
How to change the password ?
because i've copied the configurations from another router, the passwords will be saved in the new router, and I need to change the passwords.

Thanks

To reset Cisco 877 password, follow these steps:

Step 1: Enter the configure terminal command to enter global configuration mode:

Router# configure terminal

Step 2: Enter the enable secret command to reset the enable secret password in the router:

Router(config)# enable secret password

Step 3: Enter exit to exit global configuration mode:

Router(config)# exit

Step 4: Save your configuration changes:

Router# copy running-config startup-config

thank you for your kind reply, but this is not what I need.
I need to configure the ADSL user name and the password
(Ex: aaa@512.bb.com) like what I've in the old router:

ppp authentication chap pap callin
ppp chap hostname aaa@512.bb.com
ppp chap password 7 1218095A000A060C2378717F66
ppp pap sent-user name aaa@512.bb.com password 7 15130741162B212C21606

I've copied these 4 lines from the old router and I want to configure the same configurations in the new one with another user name and password.

You can try to change or set the enable password to PaSsWoRd:

config t
enable secret PaSsWoRd

The enable pasword PaSsWoRd command will also set the enable password, but will leave the password in plain text and visible in the router configuration. This is not affected by the service password-encryption setting.
