Customizing PPP
115391-A Rev. A 11-11
Allowing PAP Rejection
Some peers do not use PAP. If you set the Allow PAP Reject parameter to Enable,
your router accepts the Reject message from such a peer and removes PAP from
the LCP Configure-Request.
The default value is Disable.
Customizing CHAP
The Challenge Handshake Authentication Protocol imposes network security by
requiring that the peers share a plain-text secret. You specify that secret, as well as
other CHAP parameters, by configuring the parameters described in the next
sections. If you have not enabled CHAP, ignore these parameters.
Specifying the CHAP Secret
The function of the CHAP secret is similar to a password, but its use is slightly
different. Both peers on a link must have the same secret to correctly calculate
responses to challenges either one of them may send to the other during the
authentication process and network-layer negotiation phase. You can assign a text
string up to 20 characters long as the CHAP secret for this interface.
If you have enabled CHAP, specify the secret. There is no default value.

Note: For dial services that use CHAP, you must configure the CHAP secret
and the CHAP local name through the Dial menu. See Configuring Dial
Services for details.
