PPP Commands
XSR(config-if<S1>)#ppp timeout retry 20
username
This command adds or modifies a user who can manage the XSR.
This command specifies the password to be used in the PPP Challenge Handshake Authentication
Protocol (CHAP) caller identification and by the Password Authentication Protocol (PAP).
A username entry is required for each remote system that the XSR communicates with and from
which it seeks authentication for protocols such as CHAP and PAP or MSCHAP. When the XSR
receives CHAP and MSCHAP challenges, the received username is searched through the list of
usernames to find a password so it can send a response.
When the XSR receives responses to its challenges, the response name is searched through the list
of usernames and passwords and compared. When the XSR receives PAP responses it also
searches through its list of usernames to match passwords.
