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.
