CHAP challenges a client/device at regular intervals to validate itself with a username and a response, based on a hash of the ‘secret’ (password). A timer operates during which successful authentication must take place. If the timer expires before the remote end has been authenticated successfully the link will be terminated.

With both PAP and CHAP make sure the unit and the remote client/device have the same setting. e.g. if the unit is set to PAP but the remote end is set to CHAP the connection shall be refused.

In the cli, to turn on PAP (for example) the syntax would be: set ppp li 7 security pap

If you have selected a line service of ‘cslogin’, PAP or CHAP will not take place since the user will have already been authenticated. In this case setting security to PAP or CHAP will have no effect.
