What to Do if the PPP Link Disconnects

Regularly

If the device at the other end of the PPP link is not an ATR router or switch but is supplied by another vendor turn LQR (Link Quality Reporting) off on PPP links (LQR=OFF) and instead use LCP Echo Request and Echo Reply messages to determine link quality (ECHO=ON). Enter the command:

SET PPP=ppp-interface ECHO=ON LQR=OFF

What to Do if Passwords are Lost

If a user forgets their password, to reset the password from an account with

MANAGER privilege, enter the command:

SET USER=login-name PASSWORD=password

You can reset passwords for accounts with MANAGER privilege with the same command, provided the manager can login to at least one account with MANAGER privilege.
